INORGANIC SUBSTRATE/ENGINEERING PLASTIC FILM LAMINATE EQUIPPED WITH PROTECTIVE FILM, LAMINATE STACK, METHOD FOR STORING LAMINATE, AND METHOD FOR TRANSPORTING LAMINATE

摘要

According to the present invention, protection is provided, by a protective film, to an engineering plastic/inorganic substrate laminate which is employed in a production method for obtaining a flexible electronic device by temporarily supporting an engineering plastic film on an inorganic substrate, subjecting the engineering plastic film to microfabrication so as to prepare an electronic device, and removing same from the inorganic substrate.　This inorganic substrate/engineering plastic film laminate which is equipped with a protective film sequentially includes an inorganic substrate, an engineering plastic film, a pressure-sensitive adhesive layer for a protective film, and a protective film base material. The inorganic substrate/engineering plastic film laminate which is equipped with a protective film exhibits preferable preservability, handling ability, and transportability, by combining an adhesive strength Fb between the inorganic substrate and the engineering plastic film as measured by a 90-degree peel test and an adhesive strength Fp between the engineering plastic film and the protective film as measured by a 90-degree peel test, so as to satisfy the relation Fp
