Beschreibung
Zusammenfassung:	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 has1) 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., and4) the absence of a crystal nucleating agent.
