Disclosed is a thermoplastic resin composition (X1) characterized by containing (A1), (B1) and (C1) defined below, and also (D1) defined below if necessary. (A1) 1-90% by weight of an isotactic polypropylene (B1) 9-98% by weight of a propylene/ethylene/alpha-olefin copolymer containing 45-89% by mole of a constitutional unit derived from propylene, 10-25% by mole of a constitutional unit derived from ethylene, and if necessary, 0-30% by mole of a constitutional unit (a1) derived from an alpha-olefin having 4-20 carbon atoms (C1) 1-80% by weight of a styrene elastomer (D1) 0-70% by weight of an ethylene/alpha-olefin copolymer having a density of 0.850-0. 910 g/cm3 (In this connection, (A1) + (B1) + (C1) + (D1) equals 100% by weight.) |
