Abstract: Polypropylene composition comprising (A) 60 to 95 wt % of a heterophasic polypropylene (HECO) comprising 10 to 30 wt % of dispersed phase with the dispersed phase having a comonomer content of 30 to 45 wt % and the HECO having a melt flow rate MFRPP in the range of 12 to 200 g/10 min and being prepared in the presence of a Ziegler Natta catalyst (ZN-C), (B) 0 to 15 wt % of one or more elastomers, (C) 5 to 20 wt % of at least one filler wherein the polypropylene composition fulfils inequation (1) fogging≤0.02 MFRComp+0.3. The composition allows for a well-balanced combination of a good impact/stiffness balance, a good scratch resistance, low VOC and FOG emissions and remarkable good fogging values.

Abstract: C2C3 random copolymer composition with an improved balance between sealing initiation temperature (SIT) and melting point (Tm), i.e. low SIT and high melting point. In addition the inventive composition shows a broad sealing window, low hexane solubles and good optical properties, like low haze.
