Abstract:
1. Polypropylene composition comprising (a) a propylene homopolymer (H-PP) having a melt flow rate MFR (b) a propylene copolymer (C-PP) comprising (b-1) a polypropylene fraction (A) having a comonomer content of not more than 1.0 wt. %, the comomers are C (b-2) a propylene copolymer fraction (B) having a comonomer content 4.0 to 20.0 wt. %, the comomers are C wherein further (c) the propylene copolymer (C-PP) has a comonomer content of at least 2.0 wt. %, the comomers are C (d) the melt flow rate MFR (e) the weight ratio [(A)/(B)] of the polypropylene fraction (A) to the propylene copolymer fraction (B) is in the range of 30/70 to 70/30, and (f) the weight ratio [(C-PP)/(H-PP)] of the propylene copolymer (C-PP) to the propylene homopolymer(H-PP) is in the range of 95/5 to 75/25.
