Abstract:
The method for removing a coating layer has a step that prepares a laminated film having a base film (51) and a coating layer, a step that houses the laminated film and treatment water (W1) in a pressure vessel, a step that separates the laminated film into the base film (51) and the coating layer (e.g., coating layer residue (52C)) by heating the treatment water (W1) and making the pressure inside the pressure vessel (10) higher than 1 atm, and a base film recovery step that recovers the separated base film (51), the coating layer including an intermediate layer and a release agent layer, and the intermediate layer being disposed between the base film and the release agent layer.
