摘要：
The present invention is directed to a polypropylene composition (P) comprising a copolymer (C) of propylene and 1-hexene comprising a first random propylene copolymer (A) of propylene and a 1-hexene, and a second random propylene copolymer (B) of propylene and 1-hexene having a higher 1-hexene content than the first random propylene copolymer (A) as well as a plastomer (PL) being an elastomeric copolymer of ethylene and at least one C4 to C10 α-olefin. Further, the present invention is directed to an article comprising said polypropylene composition (P) and the use of said polypropylene composition (P) as a sealing layer in a multi-layer film.
