Abstract: The invention relates to a composition comprising: (A) a propylene-based polymer which is a propylene homopolymer or a propylene copolymer consisting of at least 90 wt % of propylene monomer units and at most 10 wt % of ethylene monomer units and/or an α-olefin monomer units having 4 to 10 carbon atoms and (B) a copolymer of ethylene and α-olefin comonomer having 4 to 10 carbon atoms, wherein the elastomer has a density of 0.850 to 0.910 g/cm3 and a melt flow rate of 15 to 50 dg/min measured in accordance with IS01 133 using a 2.16 kg weight and at a temperature of 190° C., wherein the amount of (A) the propylene-based polymer is 60 to 99 wt % and the amount of (B) the copolymer is 1 to 40 wt %, with respect to the total composition.
