POLYMERIC FILM CONTAINING HEAT SEALABLE AND SUBSTRATE LAYERS

摘要

A drawn polymeric film comprising an amorphous heat-sealable layer (2) and a substrate layer (1), said heat-sealable layer (2) being a heat-sealable layer comprising a copolyester of an aliphatic diol and a cycloaliphatic diol with one or more dicarboxylic acid(s), and said substrate layer (1) being an oriented substrate layer comprising a copolyester of terephthalic acid (TPA) and isophthalic acid (IPA) with one or more diol(s) selected from the group consisting of aliphatic and cycloaliphatic diols; and the use thereof as a coating layer on a metal sheet (4).
