Abstract
The present invention refers to the improved composition of a plastic film with a multi-layer structure (3 layers) with oxygen barrier properties and to moisture furthermore to acceptable adhesion between the layers for its use in food packing. Said film is composed of three layers: a central polar resin layer oxygen barrier adhered to two external layers made of polyethylene mixtures with polyethylene containing low graft levels of an unsaturated dicarboxylic acid anhydrate. The polar resin barrier preferably is a polycarboxylamida (Nylon) or a ethylene/alcohol vinylic copolymer (EVOH). the polyethylenes can be low or high density polyethylenes (LDPE or HDPE) or ethylene copolymers with alpha-olefins (LLDPE). The dicarboxylic acid anhydrate preferably is the maleic anhydrate.
