MOLD RELEASE FILM

摘要

Disclosed is a mold release film having both of a crease-resistant property and mold releasability. Specifically disclosed is a mold release film, in which at least one of the surfaces has a maximum height roughness (Rz) of 0.5 to 20 μm in the roughness curve and an average length (RSm) of the roughness curve element of 50 to 500 &mgr;m as measured in accordance with JIS B0601:2001 by using a sensing pin having a tip radius of 2 &mgr;m and a conical taper angle of 60° under such conditions that the measurement force is 0.75 mN and a cut-off values λs and λc are 2.5 μm and 0.8 mm, respectively.
