Abstract

The invention provides a method for peeling off a laminate film and capable of preventing damage to a functional film, and a method for manufacturing the functional film. The method for peeling off the laminate film, according to the invention, includes a step of transporting a laminate film (10) having a base film (12) and a functional film (14) laminated on the base film (12); and a peeling step, in which, through a first roller (122) and a second roller (124) having a smaller diameter than that of the first roller (122), the base film (12) and the functional film (14) are peeled from each other, by sandwiching the laminate film (10) to be transported from one side of the base film (12) by the first roller (122) and from one side of the functional film (14) by the second roller (124), and winding the functional film (14) around the second roller (124) and the laminate film (12) around the first roller (122).

Description

technical field [0001] The present invention relates to a method for peeling off a laminated film and a method for manufacturing a functional film. Background technique [0002] Conventionally, there is known a method of peeling off an unnecessary part of the film from a laminated film in which a plurality of films are laminated to obtain a film (functional film) as a product. For example, Patent Document 1 discloses that the sheet on which the base film and the release film are laminated is run, and the release sheet is slid while being in contact with a squeegee of a plate-shaped member to perform peeling. [0003] Furthermore, Patent Document 2 discloses a method of peeling a protective film from a photosensitive web which is a laminated film composed of a plurality of layers. In this method, a photosensitive web is sandwiched between a suction roller and a peeling roller, and the base film including the photosensitive resin layer is sucked and conveyed using the suction...
