BACKGROUND

[0002] High-altitude balloons are generally unmanned balloons, usually filled with helium or hydrogen, that are released into the stratosphere, generally attaining an altitude of about 60,000 feet (18 km) to 120,000 feet (37 km). Conditions in the stratosphere can subject the materials in the balloon to severe physical stresses at low temperatures. However, to maximize carrying capacity, lightweight high altitude balloon materials are desirable.

[0027] In various embodiments, the multilayered structure of the present invention has certain advantages over other multilayered structures, at least some of which are unexpected. In various embodiments, the present invention provides a multilayered structure having a higher strength than other films, such as a higher strength (e.g., greater tensile strength) at lower temperatures than other films. In various embodiments, the present invention provides a multilayered structure having a higher strength to weight ratio than other films. In various embodiments, the present invention provides a multilayered structure having greater dimensional stability than other films, such as higher dimensional stability at different temperatures (e.g., low temperatures) than other films. In various embodiments, the present invention provides a multilayered structure having a longer lifetime than other films. In various embodiments, the present invention provides a multilayered structure having better properties at low temperatures, such as better strength and less brittleness, than other films. In various embodiments, the present invention provides a multilayered structure having better heat scalability than other films. In various embodiments, the present invention provides a multilayered structure that is more easily recycled than other films. In various embodiments, the present invention provides a multilayered structure having greater optical clarity than other films. In various embodiments, the present invention provides a multilayered structure having better electrostatic properties than other films (e.g., less prone to static build-up). In various embodiments, the present invention provides a multilayered structure that is easier to store than other films,

[0028] In various embodiments, the multilayered structure of the present invention can have superior physical and mechanical properties as compared to other multilayered materials. In various embodiments, the multilayered structures of the present invention can be less expensive to manufacture than other films. Tie layers can be weak aspects of other multilayered structures, as seam failures often start as delamination between a strength layer (such as nylon) and a polyethylene layer, especially at cold temperatures. In various embodiments, the multilayered structures of the present invention can be free of expensive tie layers, providing a multilayered structure having improved performance over tie layer-containing multilayered structures, such as nylon-polyethylene structures. [0029] In contrast to typical polymer materials where hydrogen bonds and Van der Waals attractions between molecules provide the primary material strength, in various embodiments the multilayered structure of the present invention includes a molecular network where the molecules have been aligned to a greater degree via extrusion of multiple thinner layers, allowing the strength of chemical bonds to significantly enhance the strength of the multilayered structure. For example, in various embodiments, the greater alignment of polymer molecules can allow a larger proportion of the carbon-carbon bonds in the polymer backbone to enhance the strength of the multilayered structure, such that the strength of the film is greater that a corresponding multilayered structure having the same composition but a lower proportion of aligned polymer molecules. In various embodiments, the multilayered structure of the present invention can have better tensile strength, less low temperature brittleness, greater elongation before deformation, or a combination thereof, as compared to other multilayered structures. While some multilayered structures require a tradeoff between elongation and strength, for example ultrahigh molecular weight polyethylene has high tensile strength but poor elongation prior to yield performance, in various embodiments the multilayered structure of the present invention provides multilayered structures that are strong, flexible and elastic over a wide temperature range.

[0030] Low temperature performance can suffer from materials that become glassy or crystalline at low temperatures, causing brittleness of the material. In various embodiments, the multilayered structure of the present invention includes layers formed from a polymer blend that is miscible over a broad range of temperatures to maintain flexibility at low temperatures, such as a broader temperature range than the polymer blends used to form other multilayered structures. In various embodiments, the multilayered structure of the present invention includes layers formed from a polymer blend that is miscible over a wide temperature range from far below freezing to oven temperatures and over the range of pressures seen in a film extruder. In various embodiments, the multilayered structure of the present invention can become stronger, more elastic, and have greater elongation at yield as the temperature drops from room

temperature to about -60 °C or lower. In various embodiments, the multilayered structure of the present invention can have a greater elongation at yield than other multilayered structures, such as at -20 °C, -40 °C, or -60 °C, of equal to or greater than 6%, 7%, 8%, or equal to or greater than 9% or more, which can be advantageous for high altitude balloon use. [0031] In various embodiments, the flexibility and elongation before yield of the multilayered structure of the present invention can reduce the concentration of stress and allows the film load to be distributed over a larger area allowing for the construction of "'super- pressure" balloons. These balloons are strong and light providing for large payloads to be carried for long periods of time. The super pressure balloons can operate at a pressure of approximately 2000 Pascals for 50 foot diameter balloons. This can lead to very high loads on the films amounting to thousands of pounds per gore for a film that is between 1.3 and 2 mils in thickness.

Multilayered structure.

[0074] In various embodiments, the present invention provides a multilayered structure.

The multilayered structure can include at least one A layer (a) including an olefin polymer or copolymer, at least one B layer (b) including a cyclic olefin polymer or copolymer, and at least one A layer (c) including an olefin polymer or copolymer. In various embodiments, the present invention provides a multilayered structure having multiple layers that each include a cyclic olefin polymer or copolymer. For example, in various embodiments, the present invention provides a multilayered structure having more than one B layer. In various embodiments, the present invention provides a multilayered structure including a layer (a) including a cyclic olefin polymer or copolymer and an olefin polymer or copolymer, and a layer (b) including a cyclic olefin polymer or copolymer and an olefin polymer or copolymer. Layer (a) can be substantially in contact with layer (b). In some embodiments, one or both of layer (a) and layer (b) can be a B layer. The olefin polymer or copolymer can be a mixture of linear low-density polyethylene (LLDPE) and ultra low-density polyethylene (ULDPE). The multilayered structure is a multilayered film that can be suitable for use as a balloon skin, such as for high-altitude balloons, [0075] Each layer can be partially or fully in contact with the one or more adjacent layers. For one layer to contact the other layer, the surface of one layer can be fused to the other, such that the planar distributions of material in each layer are adjacent to the another. In some examples, contacting can include at least some mixing of the materials in one layer with the other layer. In some examples, contacting can include a different material at the interface between layers due to a chemical reaction at the time of fusing or later, due to the application of adhesive between the layers, or a combination thereof. Two contacting layers having

substantially all of the major side of at least one layer contacting at least part of the major side of another layer can be fully contacting one another. In another example, two layers can be fully contacting one another when substantially all of one major side of one layer is contacting substantially all of one major side of the other layer. Two layers can be partially contacting one another when a major side from one layer contacts the a major side of another layer, but less than all of a major side of one layer is contacting less than all of a major side of the other layer.

When a group of similar layers (e.g., at least one B layer (b) including layers (bl) and (b2)) is referred to at being at least partially in contact with another layer, each member of the group need not be in partial contact with the other layer; however, at least one member of the group contacts the other layer (e.g., at least partially, or fully).

[0076] Each A layer can include one more olefin polymers or copolymers. Each B layer can include one or more cyclic olefin polymers or copolymers. The multilayered structure can include A layers (e.g., olefin polymer or copolymer-containing layers that include at least one olefin polymer or copolymer) alternating with B layers (e.g., cyclic olefin polymer or copolymer- containing layers that include at least one cyclic olefin polymer or copolymer). For example, the multilayered structure can have the structure A-B-A, A-A-B-A, AA--BB-A, or AA-BB-AA, wherein each example structure includes A layers alternating with B layers. In some examples, each A layer alternates with each B layer, such as A-B-A, A-B-A-B, A-B-A-B-A, and the like.

[0077] The multilayered structure can include A layers on one or more major external surface thereof (e.g., wherein the multilayered structure has two major external surfaces: the top surface and the bottom surface). The multilayered structure can include an A layer on one major external surface. The multilayered structure can include an A layer on each major external surface. Each B layer can include either a B layer or an A layer on each major surface thereof. Each major surface of each A layer in the multilayered structure can have either a B layer thereon, an A layer thereon, or is an external surface on the multilayered structure.

[0078] In various embodiments, the multilayered structure includes is free of layers other than A layers and B layers. The total thickness of the multilayered structure can be substantially the same as the total thickness of all of the A layers in the multilayered structure and all of the B layers in the multilayered structure. Each A layer can be at least partially in contact with (e.g., partially or fully in contact with) one or more B layers. Each B layer can be at least partially in contact with (e.g., partially or fully in contact with) one or more A layers.

[0079] In some embodiments, one or more layers farther from an external surface of the multilayered structure can include a lower percentage of olefin polymer or copolymer than one or more layers that are closer to a major external surface of the multilayered structure. In some embodiments, one or more layers further from an external surface of the multilayered structure can include a higher percentage of cyclic olefin polymer or copolymer than one or more layers that are closer to a major external surface of the multilayered structure.

[0080] In various embodiments, the multilayered structure can be free of adhesive between one or more layers. In various embodiments, the multilayered structure can be free of tie layers between one or more layers.

[0081] The multilayered structure can have any suitable total olefin polymer or copolymer content, such as about 1 wt% to about 99 wt%, about 30 wt% to about 99 wt%, or about 1 wt% or less, or less than, equal to, or greater than about 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 86, 88, 90, 92, 94, 95, 96, 97, 98, or about 99 wt% or more of the multilayered structure.

Multilayered structure including COC polymer or copolymer in layers (a) and (b).

[00113] In various embodiments, the present invention provides a multilayered structure having multiple layers that each include a cyclic olefin polymer or copolymer. For example, in various embodiments, the present invention provides a multilayered structure having more than one B layer. In various embodiments, the present invention provides a multilayered structure including a layer (a) including a cyclic olefin polymer or copolymer and an olefin polymer or copolymer, and a layer (b) including a cyclic olefin polymer or copolymer and an olefin polymer or copolymer. Layer (a) can be substantially in contact with layer (b). In some embodiments, one or both of layer (a) and layer (b) can be a B layer, as described herein. The olefin polymer or copolymer can be any suitable one or more olefin polymers or copolymers, such linear low- density polyethylene (LLDPE), ultra low-density polyethylene (ULDPE), or a mixture thereof.

[00114] The multilayered structure can include layer (a) and layer (b). Layer (a) can be substantially in contact with layer (b). Layers (a) and (b) can each be external surface layers or internal layers. Layers (a) and (b) can each independently include a cyclic olefin polymer or copolymer and an olefin polymer or copolymer. In various embodiments, the machine direction of layer (a) and layer (b) can be substantially parallel to one another. In various embodiments, the machine direction of each of layers (a), (b), (c), (d), (e), (f), (g), (h), (i), (j), (k), (1), (m), (n), and (o), or any number of layers, if the layer is present, can be substantially parallel to one another.

[00115] Embodiments of the multilayered structure including layers that independently include a cyclic olefin polymer or copolymer and an olefin polymer or copolymer, wherein each layer substantially contacts the adjacent layer, can have superior mechanical properties (e.g., tensile stress at yield, elongation at yield, and the like) as compared to a single layer having about the same overall thickness as the multilayered structure and having about the same composition including the cyclic olefin polymer or copolymer and the olefin polymer or copolymer. For example, by extruding multiple thin layers and fusing the thin layers to form the multilayered structure, a greater proportion of the molecules of the cyclic olefin poly mer or copolymer, the olefin polymer or copolymer, or a combination thereof, are substantially aligned with the machine direction than an extruded single layer having an overall thickness about equal to the overall thickness of the multilayered structure. In addition, a single layered structure is vulnerable to defects that occur during extrusion, such as gels or other imperfections in the polymer resin which can cause holes or weak points in the structure. In contrast, if a defect occurs during the extrusion of one or more layers of the multilayered structure, the other layers can help to prevent the defect from substantially affecting the mechanical and physical properties of the resulting multilayered structure.

[00116] In various embodiments of the multilayered structure, any suitable proportion of the polymers in each layer can independently be substantially aligned with the machine direction (e.g., the direction of extrusion). For example, independently in a given layer (e.g., layer (a), (b), (c), (d), (e), (f), (g), (h), (i), (j), (k), (1), (m), (n), (o), or any layer, if the layer is present), about 0.01 mol% to about 100 mol% of the cyclic olefin polymer or copolymer, the olefin polymer or copolymer, or a combination thereof, can be substantially aligned with the machine direction of the given (e.g., respective) layer, or about 10 mol to about 100 mol%, about 20 mol% to about 100 mol%, about 30 mol% to about 100 mol%, about 40 mol% to about 100 mol%, about 50 mol to about 100 mol%, about 60 mol% to about 100 mol , about 70 mol% to about 100 mol%, about 80 mol% to about 100 mol%, about 90 mol to about 100 mol , or about 0.01 mol% or less, or less than, equal to, or greater than about 0.1 mol , 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, 18, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 82, 84, 86, 88, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 99.9 mol%, or about 99.99 mol% or more. The direction a polymer is aligned with can be determined as an average direction, for example, such that a polymer with 80% of the length thereof at 10 degrees and 20% of the length thereof at 90 degrees has an average direction of 0.8*10 + 0.2*90 = 26 degrees. A polymer can be aligned with a machine direction (e.g., substantially aligned) if the average direction of the polymer is within about 0-45 degrees of the machine direction, or about 0-30 degrees, 0-20 degrees, 0-10 degrees, 0-5 degrees, or within about 45 degrees or more, or less than, equal to, or greater tha 40 degrees, 35, 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, or about 0 degrees.

[00117] The polymer chain alignment can be controlled by process settings in the extruders and the blown film die. This molecular alignment can also be impacted by the molecular structure of polymer; for example, a linear low density polyethylene can have long side chains that can align with the flow direction during extrusion followed by expansion into a star topology as the bubble is expanded during the blowing process. The molecular alignment can be seen visually as striations in the machine direction, as seen in FIG. 11. The polymer composition and chain alignment can be adjusted to tailor the properties of the film to the needs of a particular desired application. For example, a pumpkin- shaped super pressure balloon can have greater stresses in the vertical direction of the gore and can benefit from greater film strength in the machine direction. By correctly setting the extruder process conditions for each of the film layers, the polymer chain alignment can be controlled allowing customization of the film properties in the machine and transverse film directions, such as the viscoelastic properties at different temperatures. The proportion of molecular alignment can be determined from the distribution of striations seen in cross polarized light. Process settings used in the film blowing process can control the amount of chain alignment quantitatively from near zero to near complete alignment.

Layer (a) can be substantially in contact with layer (b), and layer (b) can be substantially in contact with layer (c). Layers (a) and (c) can each be external surface layers.

[00144] In various embodiments, the multila ered structure can include one or more compatibilization agents, such as within one or more layers, between layers, or a combination thereof; in some embodiments, the multilavered structure can be free of compatibilization agents, such as within one or more layers, between layers, or a combination thereof. A compatibilization agent can increase compatibility between two or more polymers, such as bonding strength or miscibility. For example, a compatibilization agent can be a tie layer between layers including the cyclic olefin polymer or copolymer and the one or more olefin polymers or copolymers that can increase the bonding strength between the layers, or can be an agent added to the layer to increase miscibility of the other components of the layer (e.g., to increase miscibility of the cyclic olefin polymer or copolymer and the one or more olefin polymers or copolymers). A compatibilization agent can be passive (e.g., does not react with other components of the layers) or reactive (e.g., reacts with other components of the layers, such as to form crosslinks or grafting). Examples of compatibilization agents can include sila e coupling agents, titanate coupling agnets, silane adhesion promoters, phenolic adhesion promotors, titanate adhesion pro motors, zirconate adhesion promotors, modified polyolefins (e.g., modified to include one or more polar groups, such as a copolymer including polyethylene repeating units and polyolefm repeating units including one or more polar- functional groups, such as a copolymer including polyethylene and repeating units formed from maleic anhydride or maieic acid, such as Bynel® 4157, or a polyethylene-co-vinyl acetate such as Polysciences Cat.

One or more compatibilization agents can independently form any suitable proportion of one or more layers of the multilayered structure including a cyclic olefin polymer or copolymer and one or more olefin polymers or copolymers, can form any suitable proportion of a tie layer in-between layers including cyclic olefin polymer or copolymer and one or more olefin polymer or copolymer, and can form any suitable proportion of the multilayered structure overall (e.g., as a component within the layers including the cyclic olefin polymer or copolymer and the one or more olefin polymers or copolymers, or between these layers), such as about 0.001 wt% to about 50 wt of the layer or of the overall structure, 0.00.1 wt% to about. 30 wt%, 0.001 wt% to about 10 wt%, 0.001 wt% to about 5 wt%, or about 0 wt% (e.g., a layer, all the layers, a tie layer in-between layers including cyclic olefin polymer or copolymer and one or more olefin polymer or copolymer, or the entire multilayered structure, can be substantially free of compatibilization agents), or about 0.001 wt or less, or less than, equal to, or greater than about 0.01 wt%, 0.1, 1, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 25, 30, 35, 40, 45, or about 50 wt% or more. If located inside a layer, the compatibilizer can form a homogeneous mixture with the other components of the layer.

[00145] Each layer of the multilayered structure can have any suitable thickness.

Each layer of the multilayered structure can be any suitable proportion of the total weight of the multilayered structure. For example, layers (a), (b), (c), (d), (e), (f), (g), (h), (i), (j), (k), (1), (m), (n), and (o), if the layer is present, can eac be independently about 0.01 wt% to about 99.99 wt% of the multilayered structure, about 10 wt% to about 90 wt%, about 1 wt% to about 40 wt%, about 5 wt% to about 25 wt%, about 0.01 wt% or less, or less than, equal to, or greater than about 0.1 wt%, 1, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85 wt%, or about 90 wt% or more.

[00150] The multilayered structure can have any suitable cold brittleness temperature

(e.g., the temperature at which failure occurs on impact, such as total or partial breaks and visible cracks, as per ASTM D-746). For example, the multilayered structure can have a cold brittleness temperature of about -60 °C to about -120 °C, about -65 °C to about -80 °C, or about -60 ^CC or more, or less than, equal to, or greater than about -65 °C, -66, -67, -68, -69, -70, -71, -72, -73, - 74, -75, -76, -77, -78, -79, -80, -82, -84, -86, -88, -90, -95, - 100, -105, -110, -115, or about -120 °C or less.

[00152] The multilayered structure can be formed in any suitable way. The multilayered structure cars be extruded using at least one of cast sheet extrusion, cast film extrusion, blown sheet extrusion, and blown film extrusion.

[00153] Various embodiments provide a balloon including the multilayered structure.

Balloon.

[00154] In various embodiments, the present invention provides a balloon including at least one embodiment of the multilayered structure described herein, wherein the multilayered structure includes the gas-enclosing portion of the balloon (e.g., the skin). The balloon can be any suitable balloon. The balloon can be a high-altitude balloon that can be filled with a suitable gas such as helium or hydrogen and can be released into the stratosphere, generally attaining an altitude from about 0 feet to about 60,000 feet (18 km) or to about 120,000 feet (37 km). The balloon can be a pumpkin balloon or a lobed balloon. Lobed balloons can be constructed with a lightweight material that is provided in diamond shaped panels of material (a gore pattern) that extend from top end to a bottom end and taper from near a midpoint toward the top and bottom ends. The diamond shaped panels can be bonded to one another along their respective longitudinal edges to form the balloon. The balloon accordingly can have a plurality of longitudinal seams extending from the top to the bottom of the balloon (one seam for each of the diamond shaped panels). The wider midpoint of each of the diamond shaped panels provides the outwardly curving shape of the balloon with respect to the narrower top and bottom ends. Optionally, a balloon can be constructed with an upper and a lower panel coupled together along an edge. In other examples a nested inner balloon (e.g., a ballonet) is provided within a larger balloon (e.g., a balloon within a balloon). The ballonet is coupled at an end of the larger balloon, for instance the bottom end of the larger balloon, and has a roughly spherical shape that fills at least a portion of the larger balloon. The ballonet (inner balloon) is inflated within the larger balloon. Inflation and deflation of the ballonet with atmospheric air provides ballast to the larger balloon by minimizing the remaining volume of the larger balloon dedicated to a lighter than air gas that provides buoyancy. The balloon, the ballonet, or both, can include the multilayered structure. The balloon can optionally include a payload, such as instruments, communications equipment, and the like, coupled with or suspended from the balloon.

[00155] In various embodiments, the present invention provides a method of using an embodiment of the balloon. In various embodiments, the present invention provides a method of making a balloon, including making a balloon that includes the multilayered structure.

Method of making the multilayered structure.

[00157] In various embodiments, the present invention provides a method of making a multilayered structure. The method can be any suitable method that forms an embodiment of the multilayered structure described herein. For example, the method can include extruding an embodiment of the multilayered structure described herein, such as a multilayered structure including at least one A layer (a) including an olefin polymer or copolymer; at least one B layer (b) including a cyclic olefin polymer or copolymer; and at least one A layer (c) including an olefin polymer or copolymer.

[00158] In some embodiments, the method can include extruding a multilayered structure, such as using blown film extrusion wherein each layer is independently extruded from separate dies, the hot extruded layers are fused together, and then the hot fused layers are stretched using air (e.g., the fused layers form a tube that is inflated with air) and cooled to form the multilayered structure, which can then be flattened and rolled onto a spindle for storage. Optional treatment steps can occur after stretching and cooling. The multilayered structure can include a layer (a) including a cyclic olefin polymer or copolymer and an olefin polymer or copolymer. The multilayered structure can include a layer (b) including a cyclic olefin polymer or copolymer and an olefin polymer or copolymer. Layer (a) can be substantially in contact with layer (b).

[00159] The method can include extruding (e.g. coextruding) one or more resins. The extrusion can be conducted with any suitable equipment. The extrusion can be, for example, at least one of cast sheet extrusion, cast film extrusion, blown sheet extrusion, and blown film extrusion. In some examples, the method can include extruding a plurality of resins, wherein each layer is extruded from at least one of the resins. The resin can include any suitable material, including any optional ingredients described herein. The method can include extruding a resin including an olefin polymer or copolymer. The method can also include extruding a resin including at least one cyclic olefin copolymer or cyclic olefin polymer. The extruded resins form any multilayered structure described herein. For example, the extruded resins form a

multilayered structure including at least one first layer including an olefin polymer or copolymer, and including at least one second layer including at least one cyclic olefin copolymer or cyclic olefin polymer. In some examples, the multilayered structure can be formed using coextrusion of any suitable combination of resins, followed by any suitable treatment such as coating, heat treatment, radiation treatment, or any combination thereof.

The bags tested at an average wall stress or hoop stress of 1437 psi at failure, with all failures occurring in the parent material (not seal failures). The test required about 12 hours, including about 4 hours of the pressure ramp up.

Example 3.5. Properties of multilayered films of Examples 3.1-3.4.

[00206] Tensile and elongation tests were performed using specimens of plastic film having a width of 1" and an initial length of 3". Tensile and elongation tests were performed as per ASTM D882 at -40 °C for each sample. Results are given in Table 3.5, wherein MD indicates "machine direction" and TD indicates "'transverse direction." The initial sample length was 3" and stretched to 15" at the end of the test. The stretching speed was 2'Vminute. No material failure was observed during the process. Sample films were also sealed along MD direction and the sealing strength was tested using the same method. [00207] The cold brittleness temperature was measured by bringing a sample secured in a flat metal fixture with a hole in the center of the fixture to various temperatures and dropping a 2-inch diameter steel ball on the sample from about 30 inches height, such that the ball lands on the sample above the hole in the fixture, and characterizing the type of failure (e.g., brittle or ductile). The cold brittleness temperature is the temperature at which brittle failures occur.

Part IV.

[00209] The COC copolymer used in this Part was TOPAS® 8007-F600.

[00210] The LLDPE used in this Part was Enable™ 27-05HH, a copolymer including repeating units from ethylene and hexene produced using a meiallocene catalyst, provided by

ExxonMobil.

[00211] The ULDPE used in this Part was Dow^® Affinity™ PF 1140G Po!yolefm

Plastomer, a copolymer including repeating untis from ethylene and octene produced using a metallocene catalyst.

[00212] In this Part, tensile stress was measured as described in Example 3.5. Elongation at yield was measured as described in Example 3.5. The cold brittleness temperature was measured as described in Example 3.5.

[00213] The cylinder maximum tensile strength was measured at -40 °C or -60 °C by welding together the long edges of a flat sheet of material, wherein the long edges are parallel to the machine direction of the material, sealing the top and bottom of the formed 40 cm circumference cylinder with a mechanical clamping fixture, and inflating the cylinder until it burst at a rate of 0.001 psi/s. Example 4.1.

[00214] Multiple 9- layered film samples were prepared using different proportions of

COC, LLDPE, and ULDPE to identify synergistic or non- linear behavior in polymer blends that can be used to select composition and processing conditions with the desired properties of strength, flexibility, and cold resistance. In this Example, 9-layer extruded plastic sheets (42 inches wide) were formed using a 9-layer blown film line, manufactured by Brampton. The extruded mixtures were produced via high shear mixing in a single screw extruder (not grooved). Extrusion occurred at 420 +/- 50 °F (216 °C +/- 28 °C) with a blow up ratio of 200 +/- 50%. Each of the 9 layers had the same composition. The multilayered structures each had a total thickness of 1.7 mils, with each of the 9 layers have a thickness ranging from 0.05 mil to 0.5 mil, and with each of the 9 layers forming about 5-25 wt% of the total weight of the multilayered structure (layer 1 = 5 wt%, layer 2 = 25 wt , layer 3 = 10 wt , layer 4 = 7 wt , layer 5 = 6 wt%, layer 6 = 7 wt%, layer 7 = 10 wt%, layer 8 = 25 wt%, layer 9 = 5 wt%). The sheets were cut into strips 1 inch wide for measurement of properties. The extrusion process used to form each layer oriented the long chains of COC, LLDPE, and ULDPE in the extrusion or machine direction through die extrusion followed by an expansion in the transverse direction by transverse film expansion in the extrusion bubble.

[00215] FIGS. 9, 10, and Table 4.1 illustrate the composition used to form each multilayered film and the properties of the resulting film (cut into a 1-inch wide strip). Sample 3135 was the only sample made from a two polymer blend, 20 wt% TOPAS® 8007-F600 and 80 wt% MDPE ExxonMobil Enable™ 35-05HH. In FIG. 9, the tensile strength (per 1 inch of width) is measured in Newtons. In FIG. 9, the elongation at yield is shown in percent. In FIG. 9, the cold temperature brittleness temperature is shown in °C. The high performance region includes mixtures containing 10 wt% to 40 wt% LLDPE, 40 wt% to 60 wt% ULDPE, and 20 wt% to 40 wt% COC. The curvature of the contour lines is due to synergistic behavior of these polymer blends. A photomicrograph of Sample 3135 under polarized light is shown in FIG. 11 , with the scale bar indicating 1.63 mil, which shows streaking in the machine direction consistent with molecular orientation caused by the extrusion process.

[00217] The identification of a miscible mixture with the correct molecular properties is important in achieving the synergistic physical properties of high strength, elasticity, and cold brittleness resistance. These properties can be seen as curvature in the contour lines of the mixture plot in FIG. 9.

[00218] One specific blend used 32 wt% COC, 49 wt% ULDPE, and 19% LLDPE which provided performance at low temperatures, flexibility and high levels of elongation prior to yield. The blending can be performed in multiple steps by compounding the mixture components prior to the extrusion process.

[00219] FIG. 12 illustrates a photomicrograph of the multilayered structure of Sample

3182. A pixel count was run on the photomicrograph to determine what proportion of the multilayered structure in the image included bubble shapes of 5 microns or larger, which corresponded to unmixed regions, glassy regions, crystalline regions, or a combination thereof. The pixel count indicated that 793811 pixels are not bubbles, while 8126 pixels are bubbles, indicating 1.1% bubbles and 98.9% not bubbles.

Example 4.2.

[00220] A 3-layer 1.8 mil balloon film was prepared using a 15.7 inch (40 cm) Kiefel blown film extrusion line with 3 extruders (2.5" (6.4 cm), 3.5" (8.9 cm), and 2.5" (6.4 cm), respectively). The extruders were run at 440 °F (227 °C) and the Die temperature was 460 °F (238 °C). The film was produced at a rate of 450 +/- 25 Ibs./hour (11.3 Svg/h) with a layer thickness directly proportional to the extruder cross sections. Identical polymer blends were run in each of the 3 extruders and die layers, these being 80% Exxon Enable™ 27-05HH and 20% Topaz® 8007-F600. The polymer blends were compounded prior to extrusion using a 52 mm ENTEK compounder using mild processing conditions of 400 °F (204 °C), a compounding rate of 400 Ibs. hour ( 181.4 g/h), and a rpm/ shear rate adjusted so that no material degradation occurred as judged by tensile strength and material color. The compounding tensile strength was measured as greater than 17 MPa at room temperature. The color was a visual white identical to the Enable ^lM 27-05HH resin as judged by placing the compounded material onto a light background and comparing to the Enable resin.

[00221] The film produced was a tube of 96 inch (244 cm) circumference with a thickness of 1.8 +/- .05 mils. Samples of this film were subjected to low temperature tensile testing.

Tensile testing was conducted on the film by preparing ' X 8" film specimens in the machine and transverse directions. The specimens were prepared to minimize any edge defects. The specimens were tested on an Instron model 3365 tester outfitted with a 3119 temperature control chamber, 2713 grips and a 2 K-N load cell. A total of 360 specimens were tested from 3 well separated samples in triplicate at 4 temperatures and 5 strain rates.

[00222] The film produced showed an increase in elongation as the film was cooled from room temperature (23 °C) to -40 °C, as illustrated in FIG. 13 showing tensile strain

(extension/length) at yield versus temperature. This increase was from 7.6 % +/- 0.25% to 8.4 % +/- 0.21% at a 52 mxn/min strain rate. FIG. 14 illustrates tensile strain at yield versus temperature. The tensile strength increased from 16 MPa +/-G.3 MPa to 38 MPa +^■/- 0.2 MPa as the temperature dropped from room temperature to -40 °C. The measurements were taken in the machine direction.
