Definitions

  • the invention relates to a multilayer material for use as packaging material and methods for its preparation.
  • a laminate with a volume hologram is known (patent N ° EP0949547), including a substrate, a first adhesive layer, a layer with a volume hologram, a second adhesive layer and a surface protective film, while a substance that provides the recording wavelength to the layer with a volume hologram is contained in the first and / or second adhesive layer.
  • the volume hologram layer itself is a photosensitive material that contains a polymer matrix, a compound that is capable of photopolymerization, an initiator photopolymerization, a sensitizing pigment and, if necessary, a plasticizer and a surfactant.
  • a substrate film, paper, metal, etc. can be used.
  • hologram elements require a large number of materials and complex technological operations for their manufacture, and accordingly entail a significant investment of time and money for production.
  • thermoset multilayer material (patent US N ° 4048736), including an outer layer of a transparent heat-resistant polymer (mainly biaxially oriented polypropylene film), a printed pattern, a layer coated with a dye (mainly a polyethylene film) and an intermediate layer.
  • a disadvantage of the known multilayer material is the insufficient reliability of the security features (since dyes can pass from one layer to another, and when it comes in contact with the product, onto the product), the need to perform an additional printing operation before the lamination process, as well as the simplicity of reproduction of security features (as for sealing one color does not require highly specialized technological equipment).
  • the basis of the claimed invention the task is to increase the reliability of the inclusion of protective features in the material and to simplify its manufacture and reduce cost by eliminating the additional technological printing operation before the lamination process.
  • the problem is solved by creating a multilayer material with protective properties for packaging products, consisting of at least two layers connected by adhesive layers, in which, according to the invention, at least one layer of material is transparent and / or translucent and at least one the adhesive layer contains a dye or a mixture of dyes.
  • the layers of the multilayer material can be made of polypropylene, polyethylene terephthalate, polyethylene, paper, metal foil, metallized film or similar materials.
  • the adhesive is a composition based on polyurethane.
  • the dye is a composition based on nitrocellulose.
  • the dye or mixture of dyes is contained in the adhesive layer in an amount of 1-30 wt.%.
  • the use of such a laminate eliminates the possibility of migration of colored pigments from the material in contact with the product, eliminates the additional printing operation from the manufacturing cycle of the material, and it also makes it difficult to reproduce security features, since a specific dye shade is difficult to reproduce without special dye mixing stations.
  • FIG. 1 An example of the structure of the proposed multilayer material in section is shown in FIG. 1, where:
  • the proposed multilayer material can be made, in particular, as follows: a dye or a mixture of dyes is mixed to obtain the desired color, then this mixture is added to the main component of the adhesive, which connects a layer of aluminum foil and a layer of transparent polyethylene, in an amount of 1-30 wt.%.
  • the multilayer material according to this invention can be used for packaging food products (for example, coffee, confectionery etc.), pharmaceutical products and other types of products that require flexible polymer packaging with protective features (for example, bags, bags, wrappers, etc.).
  • the originality of such a product can be confirmed by the unique shade of its packaging on the side of a transparent material (which is usually located on the inside of the package).
  • the material is suitable for use on automatic filling machines of both vertical and horizontal type, for example, on a horizontal packaging machine such as BOSSAR B 2500, or on a vertical packaging machine such as Ilapak Vegatronic 2000
  • the outer side of the material in the given example, this is a layer of polyethylene terephthalate) can be decorated with known ways.

Abstract

L'invention se rapporte au domaine des matériaux multicouches stratifiés et thermo-soudés utilisés en qualité de matériau d'emballage avec une fonction de protection contre les contrefaçons. Ces matériaux multicouches peut se composer exclusivement de matériaux polymères (1,5) ou d'une combinaison de ces derniers avec une feuille d'aluminium (3), une pellicule métallisée ou du papier; un des matériaux est transparent et vient se connecter à l'autre à l'aide d'un adhésif liquide (4) dans lequel on ajoute un colorant spécial conférant une teinte prédéterminée au matériau transparent.
