polypropylene sealant material with improved optical performance

Polypropylene composition comprising (a) a propylene homopolymer (H-PP) having a flow rate of melt flow rate MFR2 (230 ° C) measured according to ISO 1133 in the range of 1.0 to 20.0 g / 10min, and ( b) a propylene copolymer (C-PP) comprising (b-1) a fraction of polypropylene (a) having a comonomer content of not more than 1.0 wt%, the comonomers are α-olefins of C5 to C12 and (b-2) a propylene copolymer fraction (B) having a comonomer content 4.0 to 20.0 wt%, the comonomers are α-olefins of C5 to C12, in which case also (c) the propylene copolymer (C-PP) has a comonomer content of at least 2.0% by weight, the comonomers are α-olefins of C5 to C12, (d) the rate of melt flow MFR2 (230 ° C) measured according to ISO 1133 of the propylene homopolymer (H-PP) is higher than the flow rate MFR2 melting (230 ° C) measured according to ISO 1133 of the polypropylene fraction (a), (E) the weight ratio [(A) / (B)] of the polypropylene fraction (A) to the propylene copolymer fraction (B) is in the range DE30 / 70 to 70/30, and (f) the weight ratio [(C-PP) / (H-PP)] of the propylene copolymer (C-PP) to the propylene homopolymer (H-PP) is in the range of 95/5 to 75/25.
