Abstract: The present invention is directed to a heterophasic polypropylene composition with improved sterilization resistance and optical properties for blow molding applications, in particular for use in the blow-fill-seal process for preparing bottles. The present invention is further directed to a process for producing such a polypropylene composition using a single-site catalyst and to a container produced from such a polypropylene composition by blow molding, like a bottle, in particular a blow-fill-seal bottle, with improved haze before and after sterilization. The polypropylene composition comprises a blend of a propylene copolymer comprising 2.5 to 12.0 wt % of 1-hexene as a comonomer, and having a melt flow rate MFR2 of 0.5 to 20.0 g/10 min, and an ethylene homo- or copolymer having a melt flow rate MFR2 of 0.05 to 30.0 g/10 min and a density of 850 to 940 kg/m3, wherein the xylene cold solubles (XCS) content of the polypropylene composition is from 5.0 to 30.0 wt %.
