Abstract

Systems, kits, methods of manufacturing, and a sealing member for creating a sealed space are described. The sealing member can include a film layer and a first adhesive layer coupled to the film layer. The sealing member can also include a second adhesive layer coupled to the first adhesive layer. A plurality of apertures may extend through the second adhesive layer. Each aperture can expose at least a portion of the first adhesive layer through the second adhesive layer. A plurality of polymer particles may be disposed in the first adhesive layer. The polymer particles can be configured to dissolve in response to interaction with a switching solution.
