Claim:
1. A propylene copolymer having: (a) a melt flow rate MFR (b) a xylene cold soluble content (XCS) determined according to ISO 16152 (25° C.) in the range of 25.0 to 35.0 wt. %, based on the total amount of the propylene copolymer, and (c) a comonomer content in the range of more than 7.5 to 12.0 wt. %, based on the total amount of the propylene copolymer, wherein further; (d) the comonomer content of xylene cold soluble (XCS) fraction of the propylene copolymer is in the range of 16.0 to 28.0 wt. %, based on the total weight of the xylene cold soluble (XCS) fraction, and (e) the intrinsic viscosity (IV) determined according to DIN ISO 1628/1 (in decalin at 135° C.) of the xylene cold soluble (XCS) fraction of the propylene copolymer is in the range of more than 1.2 to below 2.5 dl/g.
