The present invention provides a release film for high-capacity multilayer ceramic capacitors (MLCC) 0.5-0.8 micron thin ceramic slurry and a manufacturing method thereof, which is characterized by using three or more layers of co-extruded polyester resin, which is stretched longitudinally, and Stretching horizontally to make recycled polyester film. Recycle polyester resin to add to the middle layer B to achieve maximum recycling efficiency. Polyester A and polyester C layers use new polyester resin raw materials, which can easily control polyester A And the flatness and roughness of the polyester C layer, the release agent liquid contains a phenyl release control agent, which can reduce the peeling force of the peeling film and the ceramic slurry and improve the production yield.nn n n The release film production process provides a release film that has good positioning accuracy during lamination, easy peeling, and high production yield when wound into a roll shape, and a manufacturing method thereof.nn n n After applying the release agent liquid on one or both sides of the polyester film, it is dried, UV cured, and then wound into a roll; the phenyl release control agent is added to the release agent liquid to coat the polyester film The cloth is treated to make it evenly distributed on the surface of the polyester film. |
