Abstract
A polypropylene resin composition is disclosed which contains a propylene polymer (A) selected from the group consisting of propylene homopolymers (A-1) and propylene-ethylene block copolymers (A-2) which are propylene-ethylene block copolymers each of which is composed of a propylene homopolymer component and a propylene-ethylene random copolymer component and has an intrinsic viscosity of from 2 to 8 dl/g, an ethylene-α-olefin copolymer (B) defined below, the amount of the polymer (A) and the amount of the copolymer (B) each being based on the combined amount of the polymer (A) and the copolymer (B) which is an ethylene-α-olefin copolymer having a melt index, as measured at 190° C., of from 1 to 40 g/10 min, and a petroleum resin (C-1) or a terpene resin (C-2) having a glass transition temperature of 90° C. or lower.
