Abstract

The invention relates to an easy-to-carry-out and effective method and a suitable device for absorbing permeates from flat structures. The method according to the invention comprises the following steps: gluing an adhesive tape containing at least one getter material onto the flat structure, storing the composite so obtained and consisting of the adhesive tape and the flat structure, and removing at least part of the adhesive tape which contains a getter material from the flat structure, the adhesive tape being designed to absorb at least partially at least one permeate from the flat structure. The invention further relates to an adhesive tape comprising at least one substrate layer having a water vapor permeation rate of <1 g/(m^2*d) (measured according to ASTM F-1249 at 38° C. and 90% relative humidity), to an adhesive compound and to at least one getter material arranged between the substrate layer and the adhesive compound or contained in the adhesive compound and capable of absorbing at least one substance capable of permeation, characterized in that the adhesive compound is reversible. In a preferred embodiment, the getter material is selected from the group comprising calcium oxide, calcium sulfate, calcium chloride, pyrogenic silica and zeolites and mixture of two or more of the above substances.
