Abstract: The invention relates to a sealing element with high sealing effect against air and moisture, which is easy to apply, and which moreover offers the possibility to reopen the sealed gap in an uncomplicated manner. Said solution is provided by an adhesive tape with differing adhesive power on the two main sides, which comprises a) a polymer foam layer and b) an outer adhesive compound layer and/or an outer thermoplastic film on one side of the polymer foam layer and is characterized in that, where the adhesive tape comprises an outer adhesive compound layer, the tape has a greater adhesive power on the side provided with the outer adhesive compound layer than on the opposing side and/or, where the adhesive tape comprises an outer thermoplastic film, the tape has a lower adhesive power on the side provided with the outer thermoplastic film than on the opposing side. The invention furthermore relates to the use of an adhesive tape according to the invention for sealing a joint between two components.

Abstract: The aim of the invention is to provide polymeric planar structures having good gas permeability, wherein a high variability with regard to the product design is made possible. This aim is achieved by means of a planar structure that comprises at least two directly successive layers, wherein the two directly successive layers are each independently from another a polymer foam or a film. At least one of the two directly successive layers has channels in the surface thereof facing the other layer, which extend from one of the edges bounding the interface plane formed by the two successive layers to another of these edges such that the channels have a free volume sufficient for vapor permeability. The invention further relates to a method for producing planar structures according to the invention, and to the use thereof.
