Abstract

A propylene resin composition composed of (A) 50 to 70% by weight, based on the total weight of (A), (B) and (C), of a propylene-ethylene block copolymer which has an ethylene content of 15 to 35 mole % and a melt flow rate (MFR) of 10 to 60 g/10 min. and in which the propylene component has an isotacticity index of at least 95%, (B) 25 to 40% by weight, based on the total weight of (A), (B) and (C), of a random copolymer of ethylene with an alpha-olefin having at least 3 carbon atoms which has an ethylene content of 60 to 85 mole %, a melt flow rate of 0.1 to 2 g/10 min. and a crystallinity, determined by the X-ray method, of not more than 10, and (C) 3 to 20% by weight, based on the total weight of (A), (B) and (C), of talc powder having an average particle size of 0.1 to 5 microns.
