Beschreibung
Zusammenfassung:	The invention relates to a heterophasic alpha-olefin random copolymer composition with a melting temperature (T m ) of at least 130°C and a flexural modulus of not higher than 1000 MPa, whereby the inventive composition comprises an alpha-olefin random copolymer component (A) of at least two alpha-olefin (co)polymer fractions (i) and (ii) having a different comonomer content, whereby at least one of the fractions is an alpha-olefin random copolymer, and a rubber component (B).
