SELF-ADHERING MATERIAL Abstract of the Disclosure A novel adhesive material comprising a plastic foam having at least a surface layer of open cells in which the surface layer of cells contains a pressure-sensitive adhesive composition formed by applying the adhesive to the foam, while the foam is maintained under pressure sufficient to cause the cell walls of the surface layer of cells to be exposed and be relatively flat so as to receive the adhesive. Upon the release of pressure, the cellular structure returns to its normal state and does not exhibit a tacky surface but will adhere to itself upon the application of pressure sufficient to expose the adhesive-containing cell walls.
