Application IN/PCT/2001/00432/MUM published 2006-01-06, filed 2001-04-19
The invention relates to a method for producing a multilayer coextrudate comprising a plastic material layer which has release properties with regard to adhesives, whereby the materials which create the release properties are arranged inside the plastic material layer. A first web (2, 22) is provided during the production of the composite. An adhesive layer (3, 23) is applied to one side of said web. The plastic material layer (4, 24) having the release properties is then applied onto said adhesive layer and is bonded with a second web (5, 25). The multilayer coextrudate is characterized in that at least two plastic material films (2, 5; 22, 25) are provided between which an adhesive layer (3, 23) and an additional layer (4, 24) having release properties with regard to the adhesive are applied.
