Abstract
Propylene copolymer composition comprising a propylene copolymer (A) having a comonomer content in the range of equal or more than 0.5 to equal or below 2.0 wt.-%, the comonomers are C5 to C12 α-olefins, and a propylene copolymer (B) having a comonomer content in the range of equal or more than 4.0 to equal or below 10.0 wt.-%, the comonomers are C5 to C12 α-olefins, wherein further the propylene copolymer composition has a comonomer content in the range of equal or more than 3.5 to equal or below 7.0 wt.-%, the comonomers are C5 to C12 α-olefins, and the weight ratio of the propylene copolymer (A) to the propylene copolymer (B) is in the range of 20/80 to below 55/45.
