Composition comprising heterophasic propylene copolymer

A composition comprising (A) a heterophasic propylene copolymer, (B) 0.01-1 wt % of a C10-C30 aliphatic carboxylic acid amide based on the total weight of the composition, and (C) a nucleating agent, wherein 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-α-olefin copolymer consisting of at least 70 wt % of propylene and at most 30 wt % of α-olefin, based on the total weight of the propylene-based matrix, and
• wherein the propylene-based matrix is present in an amount of 76 to 90 wt % based on the total heterophasic propylene copolymer, and
• (b) a dispersed ethylene-α-olefin copolymer,
• wherein the dispersed ethylene-α-olefin copolymer is present in an amount of 24 to 10 wt % based on the total heterophasic propylene 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 %,
• wherein the amount of ethylene in the ethylene-α-olefin copolymer is 30 to 38 wt %,
• wherein the propylene-based matrix has a melt flow index MFIPP as determined according to ISO1133 at 230° C. and 2.16 kg is 1.5 to 10 dg/min and the dispersed ethylene-α-olefin copolymer has a melt flow index MFIEPR as determined according to ISO1133 at 230° C. and 2.16 kg is 1 to 3 dg/min, wherein the ratio of MFIPP/MFIEPR is 0.5-15, and
• wherein the heterophasic propylene copolymer has a MFI of 10 to 100 dg/min as determined according to ISO1133 at 230° C. and 2.16 kg.
