A continuous multi-layer film has first and second film surfaces and having a curling tendency to direct the first film surface inwards. For decurling, a decurling apparatus includes a cover body for covering a moving path through which the multi-layer film is moved longitudinally. A water vapor source is contained in the cover body, for supplying water vapor to contact a surface layer portion in the multi-layer film disposed on the second film surface, to apply heat to set the surface layer portion at a higher temperature than a glass transition temperature thereof. A cooling device is contained in the cover body, disposed downstream of the water vapor source adjacently, for cooling the multi-layer film of which the surface layer portion is set at the higher temperature, to set temperature of the multi-layer film at 50 deg. C. or lower within 2 seconds. |
