Patent ID: 7128964

Claim:
A carrier film which is a laminated film having a film of a tetrafluoroethylene/ethylene copolymer laminated directly to each side of a stretched film of a polyester resin with or without the use of an adhesive in the lamination process, wherein the haze of the laminated film is at most 5% as measured in accordance with JIS K7105, wherein if an adhesive is utilized in the lamination process, the adhesive is at least one selected from the group consisting of a polyester adhesive, a polyurethane adhesive and an acrylic adhesive and wherein the tetrafluoroethylene/ethylene copolymer is a copolymer of tetrafluoroethylene, ethylene and a fluorinated vinyl monomer copolymerizable therewith (provided that tetrafluoroethylene is excluded), wherein the molar ratio of polymerized units based on tetrafluoroethylene/polymerized units based on ethylene is 50-60/50-40, and the content of polymerized units based on the fluorinated vinyl monomer is from 2 to 7 mol % to the total polymerized units.
