Olefin polymer composition, process for the preparation thereof, and film and metallized film comprising olefin polymer composition

摘要

An olefin polymer composition is described, which comprises from 80 to 98% by weight of a crystalline propylene polymer and from 2 to 20% by weight of an amorphous ethylene/ alpha -olefin copolymer having a melt flow rate of from 15 to 70 g/10 min (230 DEG C, 21.18 N). An olefin polymer composition is also described, which comprises from 2 to 20% by weight of an amorphous ethylene/ alpha -olefin copolymer composition comprising from 95 to 99.9% by weight of an amorphous ethylene/ alpha -olefin copolymer and from 0.1 to 5% by weight of an oxidation inhibitor and from 80 to 98% by weight of a crystalline propylene polymer. Furthermore, a film obtained from the composition, a metallized film obtained by metallizing the film, and the preparation process thereof are also described.
