The aim is to provide an adhesive tape that effectively protects an electronic construction from permeants, especially water, and that at the same time has good gap-filling qualities. To solve this problem an adhesive tape is proposed that has in the following order:—a carrier layer without barrier effect at least towards water and with a WVTR of at least 1 g/(m2*d) (38° C., 90% relative humidity, 50 μm layer thickness); —a layer comprising at least one getter material capable of sorbing at least water; —a water barrier ply; and—a layer of pressure-sensitive adhesive, where the carrier layer bears an outward-facing release layer and/or the layer of pressure-sensitive adhesive is lined with a release liner which has a release layer lying on the layer of pressure-sensitive adhesive.
