RELEASE FILM WITH EXCELLENT DIMENSIONAL STABILITY AND RELEASING PROPERTY COMPRISING A RELEASE COATING LAYER WITH EXCELLENT DETACHABILITY

摘要

PURPOSE: A release film is provided to form a release coating layer with different detachability to both sides through in-line coating process, and to have excellent dimensional stability and detachability.;CONSTITUTION: A release film comprises a polyethylene terephthalate film(10) as a base film, a silicone water-dispersible release coating layer(20) embodying light releasing performance through in-line coating process, and a release coating layer(30) embodying heavy releasing performance to the other side of the polyethylene terephthalate. The film satisfies equation 1: 20=RF1=60, 60=RF2=100, equation 2: TDHS = -0.43 + 0.09×MDHS, and equation 3: Rz=2.5 at the same time.;COPYRIGHT KIPO 2012
