Definitions

  • the invention relates to an adhesive tape with a carrier based on - polyolefins, which is coated on one side with adhesive, and to the use thereof, in particular for detecting the unauthorized opening of a packaging.
  • Security systems for detecting unauthorized opening are known.
  • Security labels are particularly important here.
  • US Pat. No. 4,184,701 describes security labels which are constructed from a plurality of coloring or separating layers and therefore have little adhesion of the product layers to one another. In combination with a strongly adhesive adhesive, such layers separate irreversibly from each other, which indicates the opening of the packaging.
  • DE 34 31 239 A1 describes the use of security labels for detecting the unauthorized opening of a package, consisting of a carrier material with low tear resistance.
  • the security label In combination with a strongly adhesive adhesive, the security label is irreversibly destroyed when removed and the attempt to open it is displayed.
  • the security label has a lower, first adhesive layer to be removed from a carrier and applied to the packaging on the underside of a first label material, on the upper side of which a second label material is applied via a second adhesive layer.
  • the strength of the adhesive strength of the first adhesive layer between the packaging and the first label material is different from the strength of the adhesive force of the second adhesive layer between the first label material and the second label material.
  • Packaging tapes for detecting the unauthorized opening of packaging boxes and other packaging are also known.
  • EP 0404402 A2 and US 4,876,123 describe multilayer cardboard fastener tapes which ensure a letter transfer to the packaging surface during the attempt to open and thus represent an opening safeguard.
  • this requires a relatively large and at the same time flat bonding surface.
  • security labels are used to secure the opening, it is necessary to use a suitable release paper in order to be able to apply security labels by machine.
  • the use of the necessary release paper results in an unfavorably high level of complexity when handling security labels, the accumulation of large amounts of release paper as waste product after the application of the labels and very little flexibility in adapting the security closure to the respective packaging system or to the respective opening system Packaging.
  • a certain type of security label can only be used for a certain packaging due to the size and structure of the label.
  • Plastics or foils based on cyclic polyolefins are used for various applications, preferably in the automotive, optical and electrical industries.
  • Cycloolefin copolymers are prepared, for example, by the metallocene-catalyzed polymerization of ethylene and norbomene (bicyclo- [2,2,2] -hept-2-ene). Metallocene catalysis can be used to produce both statistical (amorphous) and alternating (partially crystalline) polymers and thus adjust the mechanical properties. The concentration of norbomen determines the glass transition point of the polymer.
  • dicyclopentadiene can also be used, which is obtained in the C5 fraction from petroleum fractionation.
  • suitable catalysts such as, for example, aluminum alkyl
  • the material can be shaped into a film using common extrusion processes (for example film blowing processes, flat film extrusion).
  • the type of slitting process used is important for the tensile strength and elongation at break of the product.
  • the cut edge quality resulting from the choice of the longitudinal cutting method used can produce a sharp-edged cut edge on the one hand and a rough cut edge on the other hand, which significantly influences the tensile strength and elongation at break of the longitudinally cut films.
  • the object of the present invention is to provide an adhesive tape which is destroyed when removed from the surface of the packaging and which irreversibly divides itself or tears, which makes it impossible to re-attach in the original state, so that evidence of manipulations of a quantitative or qualitative nature on the packaged product is recognizable. Furthermore, the adhesive tape should roll off easily and have a good bond between the adhesive and the carrier film.
  • the invention relates to an adhesive tape with a carrier based on cyclic polyolefins, one side of which is provided with an adhesive.
  • the carrier has a high degree of brittleness, so that the adhesive tape as a whole shows little resistance to tearing and tear.
  • the total thicknesses are in particular between 15 to 120 ⁇ m, preferably between 20 to 70 ⁇ m.
  • the backing of the adhesive tapes according to the invention can be mixed with other polymers, such as, for example, non-cyclic polyolefins or polyesters.
  • the proportion of the polymers mixed in can be up to 50% by weight.
  • the adhesion of the adhesive to the thermoplastic film based on cyclic polyolefins is improved by corona treatment or flame pretreatment, because it is precisely the surfaces of the film based on polyolefins that can be treated by these generally known methods (such as corona and flame pretreatment) ) be treated.
  • a layer of a primer is applied between the polyolefin film and the adhesive layer.
  • a primer is an adhesive primer with a mostly multi-component structure, the adhesion-promoting effect of which is based in particular on the chemical reaction of the components with one another and with the substrate surfaces.
  • the polyolefin film is coated on the side opposite the adhesive, in particular a release coating.
  • Release coatings on the film surface opposite the adhesive are widely used in the adhesive tape industry.
  • An overview of release lacquer systems based on silicone and their use in the area of pressure sensitive adhesives can be found in "Silicone Release coating” (D. Jones, YA Peters in Handbook of Presidents Sensitive Adhesive Technology, Third Edition, edited by Donatas Satas , Van Reinhold New York, pp. 652-683).
  • rear side release coating ensures that the adhesive tapes roll off easily and evenly. Release coatings based on solvent-based carbamate systems and silicone-based systems are primarily used here.
  • Release coatings based on silicone systems are particularly suitable as release coatings for the adhesive tapes of the invention.
  • UV-curing silicone systems based on 100% are preferred as the release coating, but solvent-containing silicone systems can also be used as the release coating for the adhesive tapes according to the invention.
  • the application amount of the release coating on the carrier material is preferably 0.1 to 3 g / m2. In a further particularly preferred embodiment, a layer application of the release coating of 0.2 to 1.5 g / m 2 is set. Essentially all known adhesives with high adhesive strength can be used as adhesives on the adhesive base to be packed.
  • the adhesive of the adhesive tape according to the invention can consist of an adhesive based on solvent-containing natural rubber and acrylate adhesives. Adhesives based on acrylate dispersions are preferred; adhesives based on styrene-isoprene-styrene block copolymers are particularly preferred. These adhesive technologies are widely used in the adhesive tape industry.
  • the amount of adhesive applied to the backing material is preferably 15 to 60 g / m 2.
  • the layer application is set from 20 to 30 g / m2.
  • the adhesive tapes can be produced by known processes. An overview of conventional manufacturing processes can be found, for example, in "Coating Equipment”, Donatas Satas in the Handbook of Pressure Sensitive Adhesive Technology, second edition, edited by Donatas Satas, Van Nostrand Reinhold New York pp. 767-808. The known processes for drying and cutting the adhesive tapes can also be found in the Handbook of Pressure Sensitive Adhesive Technology, page 809-874.
  • the adhesive tapes of the invention can also be printed using conventional methods.
  • Adhesive tapes are coated on an industrial scale in wide webs, which after coating are wound into so-called mother rolls. These mother rolls are unwound again and rolled into rolls with the appropriate length. These rolls are cut into narrow rolls in the so-called slitting process.
  • the squeeze cutting method is preferably used as the longitudinal cutting method, which separates the adhesive tape in between in the running direction of the adhesive tape web by means of a rotating circular knife under a pressing force and a counter-pressure cylinder.
  • the rotating circular knife can be designed by different geometries of the cutting edge and by different surface roughnesses on the cutting flanks in such a way that the cut adhesive tape is influenced in its cutting edge roughness.
  • the cut edge roughness directly influences the tear strength of the cut adhesive tape, ie the rougher the cut edge, the lower the tear strength of the adhesive tape.
  • the reduction in tear resistance by specifying a selected cut edge roughness increases the tendency to create an adhesive tape which, after application, can no longer be removed from the bonded surface without being destroyed.
  • the security effect of adhesive tapes for detecting the unauthorized opening of a packaging can be significantly increased and the use of such products can be broadened.
  • edges of the polyolefin film therefore preferably have a serrated cut.
  • the concept of the invention also includes the use of an adhesive tape according to the invention on packaging to prove the unauthorized opening of the packaging, in that the adhesive tape is irreversibly destroyed when removed from the surface of a packaging and clearly indicates an attempted opening by tearing or splitting in the direction of thickness due to the low tear resistance.
  • the adhesive tape according to the invention is suitable for use as a security closure for clearly recognizing an unauthorized attempt to open it or an opening for a large number of valuable or sensitive goods.
  • An important field of application is the protection of various consumer goods against theft, falsification of content and protection against pirated copies. The unnoticed opening, theft and falsification of sensitive goods is avoided by using the adhesive tapes according to the invention.
  • Possible packaging options include folding boxes, bottles and tubes with screw and pressure closures, shampoo bottles, folding boxes, plastic cans and containers.
  • the surfaces of paper, cardboard, glass, polypropylene, polystyrene, polyvinyl chloride and steel are particularly suitable as packaging material in order to interact with the adhesive tapes according to the invention.
  • an adhesive tape according to the invention as a security seal to protect against unauthorized opening
  • the use of a release paper, as is necessary when using security labels is superfluous. On the one hand, this saves considerable costs, on the other hand the complexity is reduced and the resulting amount of waste is greatly reduced.
  • the use of an adhesive tape for packaging or securing products increases the flexibility of the types of packaging and closures that can be used. The size of the safety closure can be easily varied and adapted to the packaging by lightly rolling it off when manually and mechanically applying to packaging.
  • Film a film for the adhesive tapes according to the invention
  • Film 1420 is a film based on cyclic polyolefins, which is characterized in that it has low tear and tear strength.
  • a biaxially stretched film based on polypropylene from Radici was used.
  • film a and b The opposite surface of the film, which was not coated with adhesive, was provided with a back coating using conventional technologies before coating.
  • the surface of the film that was coated with adhesive was treated with Corona before coating.
  • the surface energy was> 42m N / m.
  • An adhesive based on an aqueous acrylate dispersion was used to produce the adhesive tapes according to the invention and the reference pattern.
  • the film a and b were coated with the adhesive by means of a wire knife.
  • the wire doctor blade and the coating speed were set so that a mass application of approx. 25 g / m 2 is measured after the coated film has dried.
  • Coating was carried out on a technical coater with a working width of 500 mm and a coating speed of 10 m / min.
  • Behind the coating station with wire doctor applicator was a drying tunnel that was operated with hot air (approx. 100 ° C).
  • the coated film was made up to a width of 19 mm as described in d.
  • the safety effect was determined after two days of storage at 23 ° C.
