Abstract
Polypropylene composition comprising a propylene homopolymer having a melt flow rate MFR(230° C.) in the range of 1.0 to 20.0 g/10 min and a propylene copolymer, said copolmyer comprises •a polypropylene fraction having a comonomer content of not more than 1.0 wt.-%, the comomers are Cto Cα-olefins, and •a propylene copolymer fraction having a comonomer content 4.0 to 20.0 wt.-%, the comomers are Cto Cα-olefins, wherein further •the propylene copolymer has a comonomer content of at least 2.5 wt.-%, the comomers are Cto Cα-olefins, •the melt flow rate MFR(230° C.) of the propylene homopolymer is higher than the melt flow rate MFR(230° C.) of the polypropylene fraction, •the weight ratio of the polypropylene fraction to the propylene copolymer fraction is in the range of 30/70 to 70/30, and •the weight ratio of the propylene copolymer to the propylene homopolymer is in the range of 95/5 to 75/25.
