Abstract:
Propylene copolymer having a melt flow rate MFR2 (230° C.) in the range of more than 1.0 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 7.5 to 12.0 wt.-%, wherein further the xylene cold soluble (XCS) fraction of the propylene copolymer has comonomer content in the range of 16.0 to 28.0 wt.-% and an intrinsic viscosity (IV) in the range of more than 1.2 to below 2.5 dl/g.
