The present invention provides a release coated film, an adhesive tape comprising a release coated film, and processes for preparing the same. The fluoropolymer release layer comprises a graft copolymer of (i) a base polymer containing polymerized units derived from monomers having terminal olefinic double bonds, and (ii) a moiety comprising a fluoroaliphatic group. The film may be coextruded and may subsequently be oriented in at least one direction. Alternately, the release coating can be extrusion coated onto a backing and may be subsequently oriented if the backing is orientable. Adhesives may be coated onto the release coated films either before or after orientation, or they may be coextruded along with the release coating and/or backing.
