    Abstract: The invention relates to a composition comprising (A) a heterophasic propylene copolymer and (B) an ethylene copolymer of ethylene and an alpha-olefin comonomer units having 4 to 10 carbon atoms, wherein (A) the heterophasic propylene copolymer consists of (a) a propylene-based matrix, wherein the propylene-based matrix consists of a propylene homopolymer and/or a propylene copolymer consisting of at least 70 wt % of propylene monomer units and at most 30 wt % of ethylene and/or α-olefin monomer units, based on the total weight of the propylene-based matrix and wherein the propylene-based matrix is present in an amount of 80 to 95 wt % based on the total heterophasic propylene copolymer and (b) a dispersed ethylene-α-olefin copolymer, wherein the dispersed O ethylene-α-olefin copolymer is present in an amount of 5 to 20 wt %, preferably 8 to 15 wt %, based on the total heterophasic propylene copolymer and 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 %, wherein the amount of ethylene in the ethylene-α-olefin copolymer of the heterophasic propylene copolymer is 10 to 45 wt %, preferably 30 to 38 wt %, and wherein (B) the ethylene copolymer has a density of to 0.850 to 0.910 g/cm3 and a melt flow index of 10.0 to 50.0 dg/min, preferably 30.0 dg/min, measured in accordance with ASTM D1238 (2.16 kg/190° C.), wherein the composition comprises less than 5 wt % of talc with respect to the total composition.
