THERMOPLASTIC C 2-ALPHA-OLEFIN COPOLYMER BLENDS AND FILMS

摘要

There is provided a thermoplastic film of at least two layers comprising: a first layer comprising: a third polymer having a melting point between 115 to 130°C, and a second layer in direct contact with said first layer without any interposed thermoplastic film layer, said second layer comprising: a first polymer having a melting point between 55 to 75°C, comprising a copolymer of ethylene and at least one ±-olefin, and a second polymer having a melting point between 85 to 110°C, comprising a copolymer of ethylene and at least one ±-olefin.
