Abstract

Disclosed are multilayer film structures including a layer (B) that includes a crystalline block copolymer composite (CBC) or a specified block copolymer composite (BC), including i) an ethylene polymer (EP) including at least 80 mol % polymerized ethylene; ii) an alpha-olefin-based crystalline polymer (CAOP) and iii) a block copolymer including (a) an ethylene polymer block including at least 80 mol % polymerized ethylene and (b) a crystalline alpha-olefin block (CAOB); and a layer C that includes a polyolefin having at least one melting peak greater than 125 C, the top facial surface of layer C in adhering contact with the bottom facial surface of layer B. Such multilayer film structure preferably includes (A) a seal layer A having a bottom facial surface in adhering contact with the top facial surface of layer B. Such films are suited for use in electronic device (ED) modules including an electronic device such as a PV cell.
