RELEASE FILM FOR MOLDING THIN GREEN SHEET

摘要

PROBLEM TO BE SOLVED: To provide a release film having good thermal peel stability and a flat release surface for use in the molding of a thin green sheet with a thickness of 3μm or less, which is used in the molding of the thin green sheet especially at the time of production of a ceramic laminated condenser. SOLUTION: The release film for molding the thin green sheet is obtained by providing a release layer on at least one surface of a polyester film and simultaneously satisfies formula (1) : F(80°C)/F≤2.0 and formula (2) : P-V≤700, wherein F(80°C) is the peel strength (mN/cm) between a resin sheet and the surface of the release layer in such a state that the resin sheet is laminated on the surface of the release layer, F is the peel strength (mN/cm) between the resin sheet and the surface of the release layer at the normal temperature and P-V is the maximum roughness (nm) of the surface of the release layer of the release film.
