FILM DE POLYOLEFINE MULTICOUCHE THERMORETRACTABLE

摘要

A heat shrinkable multilayer film which includes two outer layers consisting essentially of a polyethylene resin, and one or more inner layers interposed between the outer layers, wherein at least one of the inner layers comprises a blend of a polypropylene resin and a substantially linear ethylene/alpha-olefin copolymer, wherein said copolymer has a molecular weight distribution Mw/Mn of not greater than about 2 and a melt flow ratio I10/I2 of not smaller than 7.0.
