Abstract
A thermoplastic resin composition comprising 5 to 50% by weight of a propylene homopolymer(A) having an intrinsic viscosity measured in a tetralin solution at 135° C. of 1.2 dl/g or more, having a boiling heptane-insoluble portion content of 5.0 to 50.0% by weight and having an intrinsic viscosity measured in a tetralin solution at 135° C. of the boiling heptane-insoluble portion of 4.3 dl/g or less, and 95 to 50% by weight of a propylene-based resin(B) consisting of a propylene homopolymer(B1) having an isotactic pentad fraction of 0.970 or more or a composition consisting of at least 65% by weight of the propylene homopolymer(B1) and up to 35% by weight of an ethylene-propylene random copolymer(B2).
