PURPOSE:To obtain a composition which gives films excellent in various kinds of physical properties by adding a specific ethylene copolymer, a higher fatty acid ester, an inorganic filler and a higher fatty acid amide to a specific crystalline propylene-alpha-olefin copolymer. CONSTITUTION:(A) A crystalline propylene-alpha-olefin of 110 to 150 deg.C, preferably 115 to 145 deg.C crystal melting point is mixed with (B) 1 to 30wt.%, based on the total composition, of ethylene-alpha-olefin random copolymer of 60 to 85wt.% ethylene content and less than 30% crystallinity according to X-rays, (C) 0.05 to 2wt.% of butyl stearate and/or octyl stearate, (D) 0.05 to 0.7 wt.% of a microfine filler such as natural or synthetic silica of less than 5mu average particle size and (E) 0.01 to 0.5wt.% of an amide of fatty acid of 16 or more carbon atoms to give the subject resin composition suitable for producing films. |
