The adhesive (2) label has a base layer (1) with a recess (3). Its novelty lies in the membrane (4) covering the recess. Preferably, the recess is stamped out. The membrane has selective, substance-specific permeability. It lets gas through, but not liquid. Its gas permeability is limited to molecules below a specific size. Its permeabilities are diverse. There is at least one adhesive at least locally on the base layer. The membrane is on either side and an adhesive(s) is allocated to it. On the other side there is an adhesive. Adhesive imports glue. Various weak and/or strong, detachable or permanent, transparent and/or coloured glues are used. |
