Abstract:
1. Propylene copolymer composition (P) comprising (a) a polypropylene (A) having a comonomer content of not more than 1.0 wt.-%, the comonomers are C (b) a propylene copolymer (B) having a comonomer content 4.0 to 20.0 wt.-%, the comonomers are C wherein further (i) the propylene copolymer composition (P) has a comonomer content of at least 2.5 wt.-%, the comonomers are C (ii) the ratio MFR (A)/MFR (P) is below 1.0 (iii) optionally the weight ratio of the polypropylene (A) to the propylene copolymer (B) is in the range of 30/70 to 70/30 wherein further the propylene copolymer composition (P) comprises (a) at least 20.0 wt-%. of a crystalline fraction having a lamella thickness of at least 5.70 nm, and (b) at least 10.0 wt-%. of a crystalline fraction having a lamella thickness of below than 3.0 nm, said crystalline fractions are determined by the stepwise isothermal segregation technique (SIST).
