Abstract
This invention provides a release film that, even when wound in a state where ceramic green sheets are stacked, prevents the ceramic green sheets from adhering to the back side (reverse release surface), exhibiting excellent winding and unwinding properties. The release film comprises a resin layer A on one side of a polyester film and a resin layer B on the opposite side. Resin layer A contains a non-silicone-based release agent. Pressure is applied to resin layer B and the ceramic green sheets. The charge on resin layer B relative to the ceramic green sheets, when peeled under specified testing conditions, is less than 10 kV.
