Abstract
A heterophasic propylene ethylene copolymer composition having an MFRof 1.0 to 5.0 g/10 min, a C2 content of 0.8 to 6.0 mol-%, and a Tof 153.0 to 159.0° C., comprising: a) a crystalline matrix (M) being a propylene homo- or copolymer, preferably a homopolymer; and b) an amorphous propylene-ethylene elastomer (E); wherein the heterophasic propylene ethylene copolymer composition is characterized in terms of its soluble fraction (SF) and crystalline fraction (CF) as determined by CRYSTEX QC analysis: i) from 85.0 to 90.0 wt.-% of a crystalline fraction (CF) having an iV(CF) of 2.00 to 3.00 dl/g, a C2(CF) of 0.0 to 1.5 mol-%; and ii) from 10.0 to 15.0 wt.-% of a soluble fraction (SF) having an iV(SF) of 1.30 to 2.50 dl/g and a C2(SF) of 25.0 to 40.0 mol-%.
