ABSTRACT:
A multi-layer, oriented, heat shrinkable thermoplastic film comprising: (i) a layer composed of a blend of ethylene-vinyl acetate copolymer and a linear ethylene-alpha-olefin copolymer; (ii) a layer composed of (a) a linear ethylene-alpha-olefin copolymer; (b) a material selected from the group consisting of ethylene-vinyl acetate copolymers and ethylene-n-butyl acrylate copolymers; and (c) a narrow molecular weight linear ethylene-alpha-olefin copolymer having a density of less than 0.900 g/cc; (iii) a layer composed of a vinylidene chloride copolymer or an ethylene-vinyl acetate copolymer in which the acetate moieties have been partially or completely hydrolyzed; and (iv) a layer composed of a copolymer of ethylene-vinyl acetate or a blend of ethylene-vinyl acetate copolymer and ethylene-alpha-olefin copolymer.
