Abstract

A multi-layered thermoplastic film having improved physical characteristics has a core comprising of a linear low density or linear medium density polyethylene resin and two skin layers of ethylene-vinyl acetate copolymer, the film having a machine direction elongation of at least 189%, transverse direction elongation of at least 129%, and, at 185 DEG C, a machine direction free shrink of at least 19% and a transverse direction shrink of at least 22%.
