ABSTRACT:
A multilayer thermoplastic film, and packages made from the film, comprising a layer of ethylene vinyl alcohol (EVOH) as an oxygen barrier layer, a layer of a polymer or copolymer formed by the polymerization reaction with a single site catalyst and ethylene vinyl acetate (EVA) as a sealant layer, and alternatively containing a layer of EVA, said film having improved sealability and improved clarity as compared to conventional films.
