<p>A multi-layer polymer film comprising a core layer and a sealing layer,
said sealing layer comprises a propylene copolymer composition, said propylene copolymer composition
€¢ has a comonomer content in the range of 3.0 to 8.0 wt.-%, the comonomers are C 5 to C 12 ±-olefins,
€¢ comprises a polypropylene (A) and a polypropylene (B) in the weight ratio [(A)/(B)] of 20/80 to 80/20,
wherein
€¢ said polypropylene (A) has a comonomer content of equal or below 4.0 wt.-%, the comonomers are C 5 to C 12 ±-olefins, and
€¢ said propylene copolymer (B) has a comonomer content of 4.0 to 20.0 wt.-%, the comonomers are C 5 to C 12 ±-olefins.</p> |
