A polypropylene composition made from or containing (i) component (1) made from or containing a propylene/ethylene copolymer containing 2 to 4% by weight of an ethylene-derived unit, based upon the total weight of the propylene/ethylene copolymer; and (ii) component (2) made from or containing an ethylene/propylene copolymer containing 65 to 87% by weight of an ethylene-derived unit, based upon the total weight of the ethylene/propylene copolymer; wherein the polypropylene composition has 1) a weight ratio of component (1) to component (2) in the range of 65:35 to 77:23, 2) an intrinsic viscosity of xylene solubles (XSIV) in the range of 0.8 to 1.4 dl/g, 3) a MFR (at 230° C. under a load of 2.16 kg) in the range of 15 to 40 g/10 min., and 4) the absence of a crystal nucleating agent.
