Method for producing an adhesive sealing tape

Abstract

The aim is to provide an efficient method for producing a multi-layer adhesive tape having a heat-sealing layer and a pressure sensitive adhesive that results in effective composite adhesion of the individual layers to one another. This is accomplished with a method for producing an adhesive sealing tape covered with a release liner, said method comprising a) heating a pressure-sensitive adhesive in such a way that the pressure-sensitive adhesive is present as a melt; and b) producing a composite in a roll nip in such a way that a hotmelt adhesive layer is lying on one roll, a release liner is lying on the other roll, the release liner having an outer release layer, and this outer release layer pointing away from the roll surface, the pressure-sensitive adhesive melt is introduced into the roll nip and by rotation of the rolls, contacting of the layers and cooling, a composite is obtained with the sequence of hotmelt adhesive layer—pressure-sensitive adhesive—release liner, the release liner remaining on the pressure-sensitive adhesive until the adhesive tape is applied.
