Abstract: The invention relates to a composition comprising (A) a heterophasic propylene copolymer, (B) a propylene homopolymer and (C) a polyolefin-based elastomer, wherein (A) the heterophasic propylene copolymer consists of (al) a propylene-based matrix, wherein the propylene-based matrix consists of a propylene homopolymer and/or a propylene copolymer consisting of at least 90 wt % of propylene monomer units and at most 10 wt % of ethylene and/or α-olefin monomer units, based on the total weight of the propylene-based matrix and (a2) a dispersed ethylene-α-olefin copolymer, wherein the sum of the total amount of propylene-based matrix and total amount of the dispersed ethylene-α-olefin copolymer in the heterophasic propylene copolymer is 100 wt %, (C) the polyolefin-based elastomer has a melt flow index of 15 to 50 dg/min measured according to ASTM D1238 with a 2.16 kg load at 190° C., the total amount of (a2) and (C) with respect to the total composition is 20.0 to 26.0 wt % and the composition has a melt flow index as measured according to ISOl133-1:2011 with a 2.16 kg load at 230° C. of 25 to 60 dg/min.
