Disclosed herein is a method for manufacturing of multilayer laminated films, comprising: (a) providing a fluoropolymer film; (b) providing a stretched polyester film; (c) providing an ethylene polymer; and (d) forming a multilayer laminated film comprising fluoropolymer/ ethylene copolymer/ stretched polyester by an extrusion coating method at a temperature of 270°C or higher, wherein the ethylene copolymer of step (c) is a copolymer of ethylene and one or more monomers selected from the group of consisting of C 1-4 alkyl acrylates, C 1-4 alkyl methacrylates, methacrylic acid, acrylic acid, glycidyl methacrylate, maleic anhydride and copolymehzed units of ethylene and a comonomer selected from the group consisting of C 4 -C 8 unsaturated anhydrides, monoesters Of C 4 -C 8 unsaturated acids having at least two carboxylic acid groups, diesters of C 4 -C 8 unsaturated acids having at least two carboxylic acid groups and mixtures of such copolymers, wherein the ethylene content in the ethylene copolymer accounts for 60-90 % by weight, preferably accounting for 65-85 % by weight, and ideally accounting for 70-80 % by weight. A multilayer laminated film manufactured by means of this method and the solar panel comprising this multilayer laminated film are also disclosed herein. |
