    摘要： An article which has been subjected to a heat treatment and has a high transparency and impact resistance before and after the heat treatment which comprises an olefin composition comprising
    a. 75 to 98 wt.-% of a heterophasic propylene/alpha-olefin copolymer comprising a polymer or a copolymer of propylene and an alpha-olefin as matrix polymer and a propylene/alpha-olefin rubber copolymer, the XCS-fraction of the heterophasic copolymer being soluble in xylene at +23°C having an intrinsic viscosity of less than 2 dl/g, and,
    b. 2 to 25 wt.-% of an ethylene homopolymer having a melt flow rate (MFR 2 ) of more than 10 g/10min and a density of less than 0.930 g/cm 3 .
