Abstract

A multiple layer polymeric film comprising three layers wherein the first layer comprises a blend of ethylene vinyl acetate copolymer, linear low-density polyethylene, and a second ethylene vinyl acetate copolymer, the second layer comprises ethylene vinyl acetate copolymer; and the third layer comprises a blend of linear low-density polyethylene and low-density polyethylene said second layer being disposed between said first and third layer and wherein each a color concentrate, a slip additive and an antiblock additive may optionally and independently be present in layers one, two and three.
