FLEXIBLE, DOPPELSCHICHTIGE POLYPROPYLENVERBUNDFOLIE |
摘要 |
<p>Flexible double-layer polypropylene laminate consisting essentially of a biaxially oriented film of isotactic polypropylene with an atactic polypropylene content of less than 6% by weight and an intrinsic viscosity of from 1.5 to 3 dl/g, adhesively bonded to a non-oriented film of isotactic polypropylene with an atactic polypropylene content of from 15 to 30% by weight, said polypropylene in said non-oriented film deriving directly from the polymerization of propylene and having an intrinsic viscosity of from 2 to 8 dl/g.</p> |
