Zusammenfassung:	Process for the production of a multilayer coextrudate with a plastic layer that has release properties with respect to adhesives, where the materials producing the release properties are located within the plastic layer, where a first web is provided in production of the coextrudate on one side of which a layer of adhesive is located, after which the plastic layer with the release properties follows, which is in turn bonded to a second web. A multilayer coextrudate is characterized by the fact that at least two plastic films are provided, between which a layer of adhesive and a further layer that has release properties with respect to the adhesive are located.
