Title: Release film and manufacturing method thereof
Inventor: SHIN JUN HO
IPC: B32B38/00
Filed: 2018-04-23
Abstract: The present invention relates to a release film and a manufacturing method thereof. The release film comprises: a polyester basic material layer having the three-dimensional center line average roughness (SRa) of the surface of 20 to 50 nm; and a release layer formed on at least one surface of the basic material layer and including an additional reaction silicon release composition. Since the thickness of the release layer is 0.5 to 2 μm, the surface roughness of general basic material layers can be significantly lowered through the thick release layer so costs can be reduced while inhibiting pinhole defects when applied to the MLCC manufacturing process. In addition, even if the release film of the present invention includes the thick release layer, blocking does not occur so the winding process of winding the release film is possible.
