ROEHRENFOERMIGER MEHRSCHICHTIGER COEXTRUDIERTER FILM.

摘要

This invention provides a coextrusion multi-layer tubler film which is superior in mechanical strength and transparency, and is free from curling. The coextrusion multi-layer tubler film comprises an outer layer made of a linear ethylene alpha -olefin copolymer having a density of from 0.900 to 0.945 gram per cubic centimeter and an inner layer made of a polypropylene-based resin or a resin composition comprising a polypropylene-based resin and an ethylene alpha -olefin copolymer having a density of from 0.850 to 0.945 gram per cubic centimeter.
