Multilayered polyolefin-based film with integrated backsheet and encapsulation performance comprising a crystalline block copolymer composite or a layer comprising a block copolymer composite

摘要

A multilayer film structure comprising a top encapsulation layer A, a tie Layer B between top Layer A and bottom Layer C and a bottom layer C, the multilayer film structure characterized in that tie Layer B comprises a crystalline block composite resin or a block composite resin and bottom Layer C comprises a polyolefin having at least one melting point greater than 125° C.
