HEAT-SHRINKABLE MULTILAYER FILMS

摘要

FIELD: chemistry. ^ SUBSTANCE: film has a surface layer a) made from at least one olefin polymer and/or a copolymer of ethylene with vinyl acetate; a layer b) made from a mixture of copolymers of ethylene with (meth)acrylic acid with flow melt index (PEP) not more than 4 dg/min on one side and from not more than 4 dg/min to not more than 5 mg/min on the other side; a barrier layer c) made from polyvinylidene chloride or a copolymer of vinylidene chloride with methacrylic acid; a layer d) made from the same mixture of ionomers as that forming layer b, or from a copolymer of ethylene with vinylacetate and a heat-sealable layer e) made from at least one polyolefin and/or copolymer of ethylene with vinylacetate. ^ EFFECT: films obtained in form of sleeve packets are suitable for packing food products. ^ 22 cl, 1 ex
