Abstract

Multi-layer thermally retractable film for packaging and manufacture of various products, realized through a process of coextrusion, cooling in water and biorientation consisting of at least three layer of which: - the internal layer is formed by at least one copolymer of ethylene and one α-olefin having from 5 to 18 atoms of carbon; the first of the two external layers is formed from a polymeric polyolefin material chosen from among the ethylene-propylene copolymers and ethylene-propylene-butene and their mixtures; the second of the two external layers is formed from a polymeric polyolefin material chosen from among the ethylene-propylene copolymers and ethylene-propylene-butene and their mixtures and one copolymer of ethylene-vinylacetate or ethylene-alkylacrylate. The thermally retractable film according to the invention offers elevated optical characteristics, good weldability, elevated retraction, good resistance to tearing and perforation.
