Abstract:
A propylene resin composition consisting essentially of the following components (a) and (b):component (a): 100 parts by weight of a propylene-ethylene block copolymer composed of 62 to 76% by weight of crystalline polypropylene homopolymer moiety (unit A moiety), and 24 to 38% by weight of ethylene-propylene random copolymer moiety (unit B moiety) having an ethylene content of 30 to 60% by weight and a weight-average molecular weight (Mw) of 200,000 to 400,000, the melt flow rate of the component (a) being from 25 to 100 g/10 min, wherein the melt flow rate is measured at 230.degree. C. under a load of 2.16 kg; andcomponent (b): 1 to 60 parts by weight of an ethylene-.alpha.-olefin copolymer rubber containing 20 to 50% by weight of an .alpha.-olefin having 3 to 16 carbon atoms, and wherein the composition does not contain talc.
