Definitions

  • the present invention relates to a packaging material comprising a layer of silicon oxide and a layer of polyolefin. It relates more particularly to a structure comprising a film covered with silicon oxide and a polyolefin film, an adhesion binder being disposed between the silicon oxide and the polyolefin film.
  • a packaging material comprising a layer of silicon oxide and a layer of polyolefin.
  • It relates more particularly to a structure comprising a film covered with silicon oxide and a polyolefin film, an adhesion binder being disposed between the silicon oxide and the polyolefin film.
  • One can, for example, on the side of the polyolefin film hot paste this material on cardboard, then cover each side of the assembly obtained with a polyethylene sheet.
  • JP 03099842 published on April 25, 1991 describes films of EVOH Vinyl silane covered with silicon oxide onto which a polypropylene sheet is bonded using a urethane adhesive.
  • JP 05330568 published on December 14, 1993 describes polyester films coated with silica onto which an ethylene resin sheet is glued using an adhesive which is an ethylene-maleic anhydride-ethyl acrylate copolymer.
  • the present invention is a material comprising a film coated with silicon oxide and a polyolefin film, such that the binder disposed between the silicon oxide and the polyolefin film is a mixture of polyurethane (A) and at least a product (B) chosen from:
  • the mixture may also contain (C) a polyethylene functionalized with carboxylic acid, carboxylic acid anhydride or epoxide groups.
  • the film covered with silicon oxide is known from the prior art. It is for example a polyester film such as polyethylene terephthalate (PET) or polybutylene terephthalate (PBT) or polyamide (PA).
  • the polyolefin film is made of polyethylene, polypropylene or ethylene copolymers such as ethylene-propylene, ethylene butene, ethylene hexene, ethylene-unsaturated carboxylic acid ester or ethylene-vinyl ester of saturated carboxylic acid copolymers.
  • the polyurethane (A) can for example be a TPU (thermoplastic elastomeric polyurethane). These products are formed from 3 basic components:
  • a linear polyol with hydroxyl terminations of molar mass for example 500 to 3,500, which can be chosen from polyesters such as adipate, azelate, isophthalate and caprolactone and from polyethers such as polyethylene glycol, polypropylene glycol and polytetramethylene glycol,
  • diisocyanate which may be aromatic such as diphenylmethane - 4.4 "diisocyanate (MDI), toluene -2, 4diisocyanate (TDI) or non-aromatic such as dicyclohexylmethane -4.4 'diisocyanate (H 12 MDI),
  • a low mass glycol such as 1-4 butanediol, ethylene glycol or 1, 4-phenylene-bis- ⁇ -hydroxy ethyl ether as chain extender.
  • the polyolefins BJ can be for example polyethylene, polypropylene, ethylene / butene copolymers, ethylene / hexene copolymers.
  • the copolymers B2 can for example be EVA (ethylene / vinyl acetate copolymer).
  • the copolymers B3 can be ethylene / alkyl (meth) acrylate copolymers.
  • the alkyl group can have up to 10 carbon atoms.
  • the products B1, B2 and B3 can also comprise anhydrides of unsaturated carboxylic acids, unsaturated carboxylic acids or unsaturated epoxides such as glycidyl (meth) acrylate, grafted or copolymerized.
  • the functionalized polyethylene ⁇ can for example be chosen from: C1 The grafted polyolefins, homo / or copolymers, C2 The grafted copolymers B2 and B3.
  • the product which is grafted can be an unsaturated epoxide such as an ester or a glycidyl ether, an unsaturated mono or dicarboxylic acid, an unsaturated carboxylic acid anhydride.
  • polyethylene BJ is advantageously used as product B. and ethylene / alkyl (meth) acrylate copolymers B3.
  • Advantageously B_3 can comprise up to 40% by weight of methyl, ethyl or butyl acrylate.
  • C.sub.3 products are advantageously used such as copolymers of ethylene, of an alkyl (meth) acrylate, either of glycidyl methacrylate or of maleic anhydride.
  • the binder of the invention can be prepared according to the known techniques of thermoplastics.
  • the quantities of products A, B and C can be for example respectively (in parts by weight):
  • compositions of the invention in% by weight are:
  • B 100% complement, B being a polyethylene BJ. or an ethylene - alkyl (meth) acrylate copolymer B3
  • A a polyetherurethane brand ELASTOLLAN 1185 A10 which is designated by A-ether; a polyesterurethane brand ELASTOLLAN C85 A 10 which is designated by A-ester.
  • B a polyethylene of melt index 7 and density 0.918 which is designated by B1-PE; an ethylene / methyl acrylate copolymer at 20% by weight of acrylate which is designated by B3-Lotryl.
  • C an ethylene / butyl acrylate / maleic anhydride copolymer which is designated by C3 - MAH. It contains by weight 15% of acrylate and 2% of anhydride.
  • An ethylene / ethyl acrylate / glycidyl methacrylate copolymer which is designated by C3 MAGLY. It contains by weight 30% of acrylate and 7% of epoxide.
  • PET films coated with silicon oxide were prepared.
  • the SiOx layer deposited in plasma is 200 Angstroms and the PET 12 microns.
  • Various binders were prepared and coextruded, and then the peel strength of the binder / PET film coated SiOx complexes was measured. The results are in Table 1.
