Abstract: A polypropylene composition (PC) being a mixed-plastic polypropylene blend having: a) an MFR2 of 5.0 to 19.0 g/10 min; b) a flexural modulus of 1500 to 2200 MPa; c) an MSB surface quality value of 3 to 19; and d) a limonene content of 0.10 to 25.0 ppm; wherein the polymeric part of said polypropylene composition (PC) has: 1) a C2(total) of 10.0 to 30.0 wt.-%; 11) a crystalline fraction (CF) content of 60.0 to 80.0 wt.-%, said CF having a C2(CF) of 0.0 to 10.0 wt.-% and an iV(CF) of 1.0 to 2.0; and a soluble fraction (SF) content of 20.0 to 40.0 wt.-%, said SF having a C2(SF) of 45.0 to 65.0 wt.-% and an iV(SF) of 1.8 to 3.6 dL/g.
