Abstract
A propylene polymer film composed of a composition comprising 100 parts by weight of a crystalline propylene polymer and 0.01 to 3 parts by weight of a non-meltable crosslinked silicone resin powder having a mean particle diameter of 0.5 to 7 microns. The film is especially suitable for packaging applications because of its good transparency, antiblocking property, bag openability, slipperiness, appearance and heat-sealability.
