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, (B) a terpolymer of propylene, an α-olefin having 4 to 10 carbon atoms and ethylene and (C) a copolymer of ethylene and an α-olefin having 4 to 10 carbon atoms, wherein the copolymer (C) has a density of at least 0.880 g/cm3, wherein the amount of the propylene-based polymer (A) is at least 60 wt % with respect to the total composition.
