MOLD RELEASE FILM

摘要

Disclosed is a practical mold release film which has excellent embeddability, while maintaining excellent properties of a mold release film using a syndiotactic polystyrene. Specifically disclosed is a mold release film having a mold release layer containing a syndiotactic polystyrene and a hydrogenated styrene thermoplastic elastomer. This mold release film is characterized in that the blending ratio of the hydrogenated styrene thermoplastic elastomer relative to the entire resin of the mold release layer is within the range of 15-35 wt%. The hydrogenated styrene thermoplastic elastomer is preferably (i) a styrene-ethylene-butylene-styrene block copolymer or (ii) a styrene-ethylene-propylene-styrene block copolymer. The mold release layer may further contain a cyclic polyolefin resin.
