AbstractA propylene polymer film is described which is composed of a composition comprising 100 parts by weight of a propylene polymer, 0.01 to 0.5 part by weight of a fine spherical silica particle and 0.3 to 5.0 parts by weight of hydroxy-fatty acid glyceride. A laminate film including a layer comprised of the above composition is also described. The film has an excellent transparency, gloss, slipperiness and adhesiveness, as well as a good adaptability to vacuum deposition.
