A label, with which an opening located in a wall can be covered, comprises a gas permeable element (30) which is embedded between a base layer (10) and an top layer (20). The base layer and top layer have openings (11, 21) that overlap each other. The gas permeable element is arranged between an adhesive layer (102) of the base layer and the top layer (20). According to embodiments, (A) the opening (21) of the top layer (20) can protrude over the edge of the opening (11) of the lower layer (10) and/or (B) the top layer (20) can protrude over the outer edge of the lower layer (10). The label has sufficient mechanical stability and prevents the discharge of adhesive. |
