DESCRIPTION

Foil bag arrangement and method for forming a foil bag arrangement

The present invention relates to a foil bag arrangement with a bag body having at least two front walls made of foil and with a band arranged in the bag body, which extends only over a part of a certain height of the front walls between a lower edge and an upper edge of the front walls, in which the front walls have side edges running between the upper edge and the lower edge and are provided with longitudinal seams and located opposite each other, and in which the bag body has a constriction between the upper edge and the lower edge of the front walls. The band is therefore also arranged at a distance from the upper and lower edges of the front walls.

The present invention also relates to a method of forming such a foil bag arrangement.

In the context of the invention, the foil bag arrangement with the bag body on one side and the web on the other comprises at least two elements which can be manufactured and arranged independently of one another.

Once filled, the bag body is closed and thus forms a foil package. The foil bag arrangement according to the invention is particularly suitable for packaging liquid, including pasty or generally pourable products, whereby the bag body is pumped outwards when filled and thus acquires a certain strength and stability. Basically, the bag body can also be equipped with a foot base, a separately attached or punched carrying handle, pouring spouts, reclosers or the like.

A generic foil bag arrangement with a bag body formed by at least two front walls and a band is known from EP 3168 169 B1. According to one possible design (Figure 3), the bag body has a concave constriction between an upper edge and a lower edge of the front walls, so that a separate band is held in a vertical direction by geometrical connection.

It is preferably provided that the band is otherwise arranged loosely or at least largely loosely on the bag body.

Like the present invention, EP 3168169 B1 relates to the simplest possible recycling of materials, for which the bag body and the web can be made separately and can also be disposed of separately. It can also be provided that the bag body is completely unprinted. Depending on the polymer material used, the bag body can be transparent, cloudy, opaque or single-coloured, including white or black. It should be noted that printing inks can represent undesirable foreign substances, especially in the case of polymer recycling. In synthetic materials, conventional dyes can be physiologically problematic for plastics and can also impair the mechanical and optical properties of the resulting recycling.

If, on the other hand, the bag body is completely unprinted, very high-quality recyclates can be produced by separately recycling unprinted waste of the same type without any unwanted "down-cycling" taking place. With a view to sustainable materials management, for example, it is desirable to re-manufacture the same or comparable product from packaging after recycling.

Furthermore, a recyclable foil bag arrangement should also have a high-quality appearance and an attractive graphic design. In addition, information for the user, such as content information, instructions for use, manufacturer's information or similar, should be provided.

According to EP 3168169 B1, a circumferentially closed and otherwise loose band may be placed around a concave shape of the bag body. In order to reproduce the concave shape, the band may be shrink-wrapped. A band with a uniform annular shape, i.e. with substantially straight edges, does not come into uniform contact with the bag body, which impairs its appearance. In the case of a shrink-wrapped band, manual separation may be difficult even when the bag body is empty.

According to JPH 584640 U, a bag body is provided with a band. Even if the bag body is lifted by the contained liquid product, the ring-shaped band can be accidentally or intentionally removed from the filled bag body, in which case the information required by a user is no longer available.

The same applies to a foil bag arrangement described in WO 2003/097473A1.

EP 3594 144 A1 also refers to improved recycling, whereby after removing a section of printed material, an unprinted and preferably unmixed bag body remains. To do this, the user has to deliberately tear off the section of material, whereby the production of the very high-quality foil bag assembly also requires a certain amount of effort.

The same also applies to a packaging arrangement according to US 6280085 B1, in which an outer layer can be removed.

Against the background of the state of the art, the present invention has the object of providing a foil packaging bag arrangement which is simply and inexpensively constructed, has an attractive design and can be handled with particular ease by a user for recycling.

The object of the invention and the solution of the objective are a foil bag arrangement according to claim 1 and a method for forming the foil bag arrangement according to claim 10.

Starting from a generic foil bag arrangement with a band in a constriction of a bag body, according to the invention it is provided that the constriction is formed by an upper and a lower offset of the side edges, the distance between the upper and lower offset corresponding to at least one height of the band.

A contact surface for the web is thus defined between the upper and lower offsets, and a geometrically connected reception of the web of a suitable size can also be achieved there. In the upper and lower offsets, the bag is retracted to a certain extent inwards, whereby, in accordance with a preferred design of the invention, the side edges between the upper and lower offsets run straight and thus also form a straight contact surface for the web when viewed from above. In relation to a filled film bag, a substantially cylindrical section is formed between the upper and lower offsets, which holds the web.

When the bag body is filled with a liquid, pasty or pourable material, the front walls of the flexible film bulge outwards. Especially when the bag body is filled with a liquid and is completely or almost completely filled, a geometric connection of the web is guaranteed if the web is of the appropriate size.

However, if the bag body is completely or partially emptied, the front walls can also be deformed inwards of the bag body, so that the strip can then be easily removed. This is the case in particular if, according to a preferred design of the invention, the strip is held in the bag body only or mainly by geometric connection.

As described below, a light attachment of the band to the bag body, for example by means of hot melt adhesive or another adhesive, may be provided due to the manufacturing process. If such a preferably only light and only point-like connection is not already released beforehand, it can also be easily separated by a user within the scope of the invention.

In the case of a completely emptied bag body and also in the case of a partially emptied bag body, the band will usually also lift off the bag body. It is therefore obvious to a user that the two components can and should be separated very easily.

It is even possible that if the film is thin and the bag body collapses, the band practically falls off by itself, so that the user must then grab and manipulate both parts separately and thus be directed to proper separate disposal making easy recycling possible. In particular, in no case is it necessary to tear off the band in a complicated way.

In this way, the effort for the user is reduced to a minimum, which increases the chances of good acceptance and therefore a high recycling rate.

As described above, the edges between the upper offset and the lower offset are straight or substantially straight according to a preferred design of the invention. In addition, in a simple design of the bag body, it is also convenient for the side edges to run straight at least in a partial area above the upper offset and at least in a partial area below the lower offset. However, towards the corners of the bag body there may of course also be roundings, chamfers or the like.

In the context of the invention, the upper offset and the lower offset, in contrast to a completely concave shape known from the prior art, should be spatially limited in order to enable a clearly defined receiving area for the web and a contact that is as smooth as possible. However, with regard to the handling of the bag body and the mechanical load-bearing capacity, right-angled folds, sharp corners or the like should be avoided. For example, the longitudinal seams in the area of the upper offset and the lower offset can run obliquely over a short length, in particular at an angle of between 30° and 60° to the adjacent straight sections.

Against this background, according to a preferred variant of the invention, the upper displacement and the lower displacement extend respectively over a displacement height of between 2 mm and 20 mm, in particular between 4 mm and 15 mm. The displacement height should be determined along the height of the front walls.

Furthermore, it is preferably provided that the upper offset and the lower offset along a transverse direction extend over a offset width of between 2 mm and 20 mm, in particular between 4 mm and 15 mm. The offset width therefore indicates to what extent the side edges between the upper offset and the lower offset are retracted inwards towards the bag body. If the offset width is too small, the band can accidentally or intentionally come loose from the filled bag body, which is generally undesirable. If the offset width is too large, it may be more difficult to release the band from the bag body after complete or partial emptying, thereby reducing the total filling volume of the bag body.

The specified offset width is also suitable with regard to the usual tolerances of the belt. It is self-evident that the circumferential length of the usually exactly cylindrical belt is adapted to the circumferential length of the bag body between the upper offset and the lower offset in the filled state or corresponds to this value.

If, as a result, the band has a gap, in particular a slight gap, a clamping fixation to the bag body during filling can be achieved in any case.

If, due to the manufacturing process, there is an excess between the upper and lower offset in relation to the circumferential length of the bag body, an appropriate offset width can prevent the band from being lost. However, it is then possible that the band twists relative to the bag body, which is acceptable in many cases. If twisting is to be avoided, an easily removable fixation using adhesive or similar is possible, as already described above.

In the context of the invention, the strip is intended to enable a print or a graphic design in general, independently of the bag body itself. In this context, the strip may also have reliefs, perforations or the like, in addition to or alternatively to a print, which may be applied both in areas and over the entire surface. It is often desirable to make the strip attractive to the user and also to provide information relevant to the user, such as information about the manufacturer, brands, product names, consumer information, content information or the like.

In addition, the band can also contribute to a certain stabilization of the bag body. This stabilization is ensured in particular when the bag body is completely or at least largely filled with a liquid, a pasty material or a pourable material, when the front walls bulge outwards. Particularly in the filled state, particularly high loads can act on the bag body. The band can, for example, help to ensure that the bag body does not burst under load or bursts only later.

With regard to the graphic design, the arrangement of information and the mechanical stabilization, according to a preferred design of the invention it is provided that the band extends over 10% to 90%, preferably 20% to 70%, particularly preferably 30% to 60% of the height of the front walls.

The absolute height of the band then obviously also depends on the dimensions of the bag body and can be, for example, within a range between 40 mm and 300 mm.

As explained above, the distance between the upper and lower offset corresponds at least to the height of the web. This ensures that the web can lie evenly and largely flat against the filled bag body between the upper and lower offset. These properties are already achieved if the distance between the upper and lower offsets corresponds exactly to the height of the web. However, the distance between the upper and lower offsets can also be increased by 1 mm to 40 mm, in particular 1 mm to 15 mm, to compensate for certain manufacturing variations. Of course, an even greater oversize in terms of height is also possible, but then the web can also slide along the height if it is not attached to the bag body by a detachable fastening.

According to the present invention, the bag body and the band should be easily handled and disposed of separately by a user after use of the foil bag arrangement, in particular to enable better recycling. It is understood that this measure is convenient and is provided for precisely if the bag body, on the one hand, and the band, on the other, are made of different materials and/or are prepared differently.

According to the present invention, it is provided that the front walls are formed from foil. In contrast, for example, to deep-drawn packages, the foil is flexible and malleable, so that the strip can be easily removed from the bag body after it has been emptied or partially emptied. The thickness of the foil is typically in a range between 30 |jm and 250 |jm, in particular between 50 |jm and 150 |jm.

Since the web can be used as a printing medium, the bag body can be 90 to 95% or completely unprinted on its surface within the scope of the invention. It should be noted that printing plastic films is partly a process-intensive task and also requires particularly adhesive printing inks, which are usually not or only with great effort to separate from the plastic itself in a recycling process. The corresponding dyes therefore often represent a chemically undesirable foreign substance in a recycling process. This applies in particular to recycled materials that must meet high optical requirements and/or be physiologically harmless, such as food or beverage packaging.

Particularly high-quality recycling is also possible if the front walls and preferably the entire bag body are made from a single type of polymer, in particular a polyolefin.

In this context, a single type is understood to mean in particular that the front walls and in particular the entire bag body are made of a plastic material of a polymer type such as polyethylene or polypropylene. In this respect, it should be noted that the film of the front walls can be composed of several layers, and that the bag body can also have additional components, such as a separate film section as a bottom fold and/or functional elements such as a spout or reclosures. In this case, these are also conveniently made of the same type of material as the front walls.

Thus, if, according to the preferred design described, several layers of the end walls and/or other components are made of polyethylene or polypropylene, these materials can also be present in different densities, such as, for example, UL Dp E, LDPE, LLDPE, MDPE, LLMDPE and HDPE. In principle, the different density classes can also be collected and recycled together, whereby such a mixture obviously has material properties that differ from the individual synthetic parent materials.

In this context, the bag body can also be formed from a single material in a narrower sense, whereby materials of a relatively narrow density range are then provided.

Particularly with regard to polyethylene, it may be useful to differentiate between high-density polyethylene (HDPE) and low-density polyethylene (LDPE), since according to Annex 5 of the German Packaging Act of 5 June 2017 (Act on the Improvement of the Separate Collection of Household Waste Containing Recyclable Materials), different abbreviations and numbers result from this (HDPE No. 2 and LDPE No. 4).

The properties of the plastic film can be influenced not only by the selection of raw materials and, if applicable, by a multi-layer structure, but also by the production, modification and processing of the plastic film. For example, the plastic film can be monoaxially or biaxially oriented, which can also improve the mechanical and/or other sealing properties.

If the synthetic film of the inner bag is made as a monolayer, it can be made of a single type of polymer or a mixture.

According to a preferred design of the invention, the plastic film for the front walls is a multi-layer film, which allows the mechanical properties, the desired barrier properties and the heat-sealing properties to be further influenced.

In particular, it can be provided that in the case of a multi-layer structure of the plastic film for the front walls, an inner layer and an outer layer have different heat-sealing properties.

For example, the inner layer is designed to form an inseparable connection by being heat-sealed to itself. This is particularly useful if, with a view to a drop test on the longitudinal sealing seams of the bag body, an unwanted burst and thus the destruction of the bag body must be reliably prevented.

As described above, the front walls and thus preferably also the complete bag body are unprinted. Depending on the material, the front walls and in particular the complete bag body can be transparent, cloudy, opaque or, if appropriate, also tinted in a single colour.

Unlike printing inks, colour pigments embedded in the polymer matrix in advance, such as titanium dioxide as white pigments, are generally less critical. In particular, no further solvents or other additives are required to incorporate the corresponding pigments. However, when recycling, care must be taken to separate unprinted materials dyed in different colours from one another, for example to avoid an unwanted grey colour of the recycled material.

Within the scope of the invention, various materials for the strip are suitable. In principle, the strip can also be made of plastic, in which case the strip as a printed element can be removed separately and, if necessary, processed into a lower-quality recycled material. If a film is intended as a strip, it should be made as thin as possible, for example with a thickness of between 10 |jm and 60 |jm. Furthermore, the film for use as a strip preferably has a high rigidity, for which correspondingly rigid plastic materials and/or an orientation can be provided to increase the rigidity. Especially in the case of an oriented film, simple polyolefins such as polyethylene (PE) and polypropylene can also be considered.

In a preferred embodiment of the invention, however, it is provided that the web is made of cardboard or paper, in which case the web can then be fed to a conventional paper recycling facility. In the case of paper recycling, in particular, it is usual for the products to be printed, so that no special measures are then required for web recycling. Another advantage is that if in a design the web is made of cardboard or paper as a printing medium, it can be printed very easily. In contrast to foils, physiologically harmless or less problematic printing inks are then also suitable.

A cardboard or paper strip can also help to stiffen the bag body in the form of a strap. If a relatively stiff cardboard strip is used as a strip beforehand, this effect is further intensified. In the case of a cardboard strip, even after the strip has been removed from the bag body, a side edge of the flattened strip can be used to spread a liquid or plasticized product when the bag body is completely or almost completely emptied, which obviously further improves the recyclability of the plastic material.

The cardboard or paper band normally has a grammage of between 30 g/m2 (grams per square meter) and 300 g/m2

The invention also relates to a method for forming the above-described foil bag arrangement, in which a bag body with two front walls and two longitudinal seams connecting the front walls is formed from a bag film, and before or after the formation of the bag body, an outer edge of the front walls is removed in a central region of the longitudinal seams in order to form an upper offset and a lower offset in the bag body produced at the longitudinal edges, and the bag body produced is filled with a liquid or pasty packaging product and closed, and a circumferentially closed band is arranged between the upper offset and the lower offset.

Various variants of the process are possible. The web can thus be laid out before filling. In a conventional process for producing the bag body, the end walls are formed by folding or joining two film webs flat on top of each other, with the longitudinal seams then also preferably formed by heat sealing. Optionally, a separate film section can also be joined together to form a foot base, which is also connected to the end walls by seams, in particular heat-sealed seams. The film section can be made of the same material as the end walls.

The upper and lower offsets can be formed in advance on the end walls or, preferably, created by cutting or punching during the moulding process. The formation of longitudinal seams by heat sealing and the removal of partial areas of the end walls to form the upper and lower offsets can be produced successively or simultaneously with combined cutting and sealing jaws.

Even in the flattened state of the bag body, a strip, in particular made of cardboard or paper, can be arranged in the area between the upper and lower offset, folded around the bag body and closed, for example, with adhesive or mechanically by means of slits or the like. In the flattened state, a certain geometric connection can also result, even if the end walls made of foil have considerable flexibility. However, as already described above, a separable fastening can also be achieved, for example by means of individual points of hot-melt adhesive.

Basically, it is also possible that the band is not formed directly around the bag body, but is prefabricated, in which case the bag body is inserted into the band, which is already circumferentially closed. This threading of the bag body into the band can take place immediately after the manufacture of the bag body or just before the filling of the bag body, with the manufacture of the bag body and the filling often taking place at different production locations and, in particular, also in different companies.

Finally, it is also possible to fill the bag body first and then place the band between the upper offset and the lower offset and close it circumferentially.

If the band is made of synthetic material, it is also possible to apply it by shrinking. However, this variant is often disadvantageous due to the flexibility of the bag body.

The invention will be explained below with the aid of a drawing which represents only one exemplary embodiment. They show:

Figure 1 a foil bag arrangement with a bag body and a band shown separately, Figure 2 the foil bag arrangement according to Figure 1 with the band on the bag body, Figure 3 the liquid-filled foil bag arrangement according to Figure 2, in perspective, Figures 4A and 4B a detailed view of alternative designs of a foil bag arrangement according to Figure 1,

Figures 5A and 5B show alternative steps for forming the foil bag arrangement according to Figure 1. Figure 1 shows a foil bag arrangement with a bag body 2 having two front walls 1 made of synthetic foil and with a band 3, which, for the sake of clarity, is shown separately.

The arrangement of the foil bag with the band 3 on the bag body 2 is shown in Figures 2 and 3.

Figures 1 to 3 show that the band 3 extends only over a portion of a given height hF between a lower edge and an upper edge of the front walls 1, the front walls 1 having side edges 5 running between the upper edge and the lower edge and being provided with longitudinal seams 4 and situated opposite one another, the bag body 2 having a constriction between the upper edge and the lower edge of the front walls 1.

According to the invention, it is provided that the constriction is formed by an upper offset 6a and a lower offset 6b of the side edges 5, the distance hZ between the upper and lower offsets 6a, 6b corresponding to at least one height he of the strip 3. The side edges 5 each run straight along a vertical direction between the upper offset 6a and the lower offset 6b, along which the previously determined heights hF, hZ, he are also determined. Above the upper offset 6a and below the lower offset 6b, an initially straight course of the side edges 5 is also provided in each case.

The band 3 is dimensioned in such a way that it is held by geometric connection between the upper offset 6a and the lower offset 6b when the bag body 2 is filled (see figure 3), without the need for additional fastening.

However, when the bag body 2 is at least partially emptied, it can be easily deformed so that the band 3 can be easily removed after use and/or slidably positioned during manufacture, provided that the band 3 is not placed directly around the filled or initially still unfilled bag body 2 during manufacture.

The user can therefore easily remove the band 3 for separate recycling. For separate recycling, it is not even necessary to tear open the band 3. It is obvious to the user that the band can and should be easily removed when the bag body 2 is emptied.

The band 3 typically extends over 10% to 90%, preferably 20% to 70% of the height hF of the front walls. It should be noted that in the preferred embodiment shown, only the band 3 is printed, while the bag body 2 is completely unprinted and is made of a single type of polypropylene or a single type of polyethylene.

The height of the band is chosen in such a way that an attractive appearance is achieved and that there is sufficient space for an imprint 7 which, in addition to a graphic design, can also include information about the user, the manufacturer, the ingredients and the like.

Additionally, Band 3 can also provide some degree of stabilization.

While the bag body 2 is made of a single type of synthetic material, in particular polyethylene or polypropylene as the usual polyolefin, the band 3 can be made simply of cardboard or paper, so that the corresponding established recycling routes can be used for the band 3.

According to the detailed view in Fig. 4A, it can be seen that the longitudinal seams 4 normally formed by heat sealing have a substantially constant width bN along their length despite the offset 6a, 6b. According to Fig. 4A, the longitudinal seams 4 thus run also in the upper offset 6a and in the lower offset 6b with a constant or substantially constant width bN, so that the filling space defined by the bag body 2 is also slightly reduced according to the upper offset 6a and the lower offset 6b. In practice, it is easily possible to form closing jaws with a contour according to Fig. 4A.

In an alternative design, it can be provided that the width bN of the longitudinal seams 4 between the upper offset 6a and the lower offset 6b is reduced in accordance with the upper offset 6a and the lower offset 6b, so that a straight end to the filling space of the bag body 2 results laterally. Although this is advantageous with regard to a uniform design of the filling space and wide, straight sealing jaws can be used, a greater overall width bN of the sealing seams 4 must be provided in order to be able to form the upper offset 6a and the lower offset 6b with the constrained intermediate region by punching or cutting. In addition, an even more reliable geometric connection can be achieved with a design according to FIG. 4<a>.

Particularly with regard to Fig. 4A, it becomes apparent that abrupt, in particular right-angled, transitions in the upper offset 6a and the lower offset 6b can be disadvantageous with respect to the usability and load-bearing capacity of the bag body 2. Against this background, the longitudinal seams 4 of the offset can, for example, form an angle of between 30° and 60° with respect to the adjacent straight areas. For this design, the upper offset 6a and the lower offset 6b can extend over an offset height hv of between 2 mm and 20 mm, for example. The offset width bv determined along a transverse direction is, for example, between 2 mm and 20 mm.

The bag body 1 may have further components in addition to the front walls 1. In the exemplary embodiment, for example, a separate film section is provided as a bottom fold 8. This film section can consist of the same plastic film as the front walls 1.

Furthermore, in the illustrated embodiment, a spout 9 is sealed at the upper edge of the front walls 1. It should be advantageously ensured that the entire bag body 2 with the front walls 1, the bottom fold 8 and the spout 9 are made of a single type of material.

The band 3 can be arranged on the bag body 1 in different ways. For example, a strip can be introduced directly during the manufacturing process with the bag body 2 still in a flat position to form the band and then placed around the bag body 2 between the upper offset 6a and the lower offset 6b, thereby creating a circumferential seal, for example by means of adhesive.

Alternatively, according to Figure 5A, the bag body 2 and a band 3 that is already circumferentially closed are initially manufactured separately, and the bag body 2 is then threaded onto the band 3. This joining can take place immediately after the manufacture of the bag body 2 or just before the filling of the bag body 2 with a liquid, a pasty material or even a pourable powder material. It should be noted that the manufacture of the bag body 2 and the filling often take place in different, spatially separated production facilities.

Finally, according to Figure 5B, it is also possible to first fill the bag body 2 and then supply a strip to form the band 3 and place it around the filled bag body 2, before closing the strip circumferentially by means of an adhesive or mechanical lock.
