Abstract

The invention relates to a method for producing a multilayer coextrudate, comprising a plastic layer that has release properties vis-vis adhesives, the release-property producing materials being disposed in the plastic layer. When the coextrudate is produced, a first web(support web I) is provided on the one side of which an adhesive layer is disposed, followed by the plastic layer having the release properties, which in turn is linked with a second web (support web II). The release layer does not show substantial migration with respect to the adhesive and the release effect does not substantially change afterwards, especially during storage.
