PRODUCTION OF MOLD RELEASE SHEET OR MOLD RELEASE FILM

Japanese Patent JP3465999

B2

PURPOSE: To produce a mold release sheet or mold release film high in productivity, not enlarged in peel force with time and excellent in adhesivity between a mold-releasing agent and a base sheet or film.
CONSTITUTION: A method for producing a mold release sheet or mold release film comprises arranging a base sheet or film (e.g. glassine paper, polyethylene terephthalate film) between mutually faced metal electrodes wherein a solid dielectric material is placed on at least one of the mutually faced surfaces, and subsequently applying an electric voltage between the metal electrodes under a pressure around the atmospheric pressure in a gas mixture comprising ≤10vol.% of a fluorine gas-containing gas and the remaining amount of an inert gas to treat the base sheet or film with the generated discharged plasma. The treated mold release sheet or film has a contact angle of ≥100 degree with water.
