Abstract: To provide a resin film which comprises an ethylene/tetrafluoroethylene copolymer and which is to be used as, for example, a rubber plug lamination film to prevent breakage at the time of producing a laminated rubber plug. The resin film comprises an ethylene/tetrafluoroethylene copolymer and is characterized in that the product of the value of the endothermic peak height ΔH (mW/mg) obtained by its DSC-analysis and the haze (%) measured at a thickness of 100 μm, is from 0.1 to 0.2 (mW/mg·%).
