Abstract:
Propylene copolymer having a melt flow rate MFR2 (230° C.) in the range of more than 0.8 to below 2.5 g/10 min, a xylene cold soluble content (XCS) in the range of 25.0 to 35.0 wt.-%, a comonomer content in the range of more than 4.5 to 10.0 wt.-%, wherein further the xylene cold soluble (XCS) fraction of the propylene copolymer has comonomer content in the range of 12.0 to 22.0 wt.-% and the xylene cold insoluble (XCI) fraction of the propylene copolymer has a Mw/Mn of more than 4.9 to 10.0.
