Abstract
A double-sided adhesive tape having a first outer impact-adhesive side and a second outer side that can be heat activated, comprising an at least two-layer product structure comprising the layers A and B. Layer A is an impact-adhesive layer chemically cross-linked by means of thermal initiation or an impact-adhesive carrier layer chemically cross-linked by means of thermal initiation. Layer B is a layer on the basis of a thermoplastic plastic. Layer A and layer B are in direct contact with each other, and the surface of layer B that is in direct contact with layer A has been corona- or plasma-pretreated. The double-sided adhesive tape is characterized in that the corona or plasma pretreatment is performed in an atmosphere comprising nitrogen, carbon dioxide, or a noble gas or a mixture of at least two of said gases.
