Abstract:
1. A transparent multilayer film comprising: A. a first film layer comprising a fluorinated copolymer resin composition wherein i) the fluorinated copolymer comprises copolymerized units of tetrafluoroethylene and copolymerized units of comonomers selected from the group consisting of ethylene, perfluorinated comonomer, and combinations thereof, and ii) at least one surface of the first film layer has been modified by a surface treatment; and B. a second film layer consisting essentially of a blend composition, said blend composition consisting essentially of an Ethylene Copolymer 1 and an Ethylene Copolymer 2; wherein said Ethylene Copolymer 1 consists essentially of copolymerized units of ethylene; optionally copolymerized units of a first olefin having a formula of CH wherein said Ethylene Copolymer 2 consists essentially of copolymerized units of ethylene; optionally copolymerized units of the first olefin; and copolymerized units of a third olefin having a formula of CH wherein R wherein a surface of the second film layer is adhered to the modified surface of the first film layer and the multilayer film laminate has an average peel strength between the first film layer and the second film layer of greater than 5 lbf/in, measured after exposing the multilayer film laminate to conditions of 85° C. and 85% relative humidity for 1000 hours.
