MANUFACTURING METHOD OF PLASTIC THIN FILM

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of plastic thin film, in which through-holes are formed and, at the same time, the film is prevented from remaining. SOLUTION: The manufacturing method of a plastic thin film provided with a plurality of through-holes penetrating the thin film in the thickness direction comprises: a heating process (S1) of laminating a material thin film on an opposite substrate made of resin material having plastic deformability lower than that of the material thin film and heating the laminated body up to at least the plastic deformable temperature of the material thin film; a pressing process (S2) of pressing the material thin film between a pressing mold which forms the through-holes and the opposite substrate to penetrate the pressing mold through the material thin film and forcing the pressing mold into the opposite substrate; a cooling process (S3) of cooling the material thin film and the opposite substrate into which the pressing mold is forced; and a releasing process (S4) of releasing the pressing mold from the material thin film and the opposite substrate.
