主权项 1. A film comprising five layers, where a middle layer comprises a polymer blend comprising: a) a polyvinylidene chloride (PVDC) polymer, wherein the PVDC polymer is a copolymer wherein a major amount of the copolymer comprises vinylidene chloride and a minor amount of the copolymer comprises one or more monomers selected from the group consisting of vinyl chloride, alkyl acrylate and alkyl methacrylate; b) unmodified ethylene vinyl acetate (EVA) with more than 40% vinyl acetate (per weight); c) polyvinyl chloride (PVC); and d) an epoxidized oil compound and optionally other additives.
