    Abstract: A release film for high-capacity multilayer ceramic capacitor (MLCC) 0.5-0.8 μm ceramic slurry and a production method thereof. The release film includes at least three layers of co-extruded polyester resin having a layer A, a layer B and a layer C, and stretching the same in longitudinal and transverse directions. In addition, the layer B includes recycled polyester resin, the layers A and C include new polyester resin raw materials, and a releasing agent having a phenyl releasing control agent. The production method for the release film includes coating a releasing agent on one or both sides of a polyester film, and winding into a roll after drying and hardening.
