Claim 3:
4. The heterophasic polypropylene composition (C) according to claim 1, wherein the first heterophasic propylene ethylene copolymer (HECO1) has one or more of the following properties:
i) an ethylene content of the soluble fraction (C2(SF)), measured by Infrared Spectroscopy during CRYSTEX analysis, in the range from 20.0 to 60.0 wt. %;
ii) an intrinsic viscosity of the crystalline fraction (IV(CF)) in the range from 1.00 to 2.00 dl/g;
iii) an ethylene content of the crystalline fraction (C2(CF)), measured by Infrared Spectroscopy during CRYSTEX analysis, in the range from 0.5 to 5.0 wt. %; and
iv) a ratio between the intrinsic viscosity of the soluble fraction and the intrinsic viscosity of the crystalline fraction (IV(SF)/IV(CF)) in the range from 1.00 to 3.00.
