ABSTRACT:
Bonding means for achieving differential adhesion of articles such as picture frames, posters, or other decorative items to wall surfaces and the like. The bonding device has adhesives secured to each of two major surfaces, with the adhesive having differential adhesion characteristics. A first adhesive is selected to achieve permanent bonding of the bonding means to the article to be displayed, with the second adhesive layer being an adhesive with low peel-low shear properties to permit removal from the wall surface whenever desired. The second adhesive provides semi-permanent positioning of the article being displayed, but permits removal thereof upon demand. The bonding means comprises a substrate with a first substantially permanent adhesive layer secured to one surface thereof, and with a co-extruded polyolefin-polyester film being bonded to the second surface thereof, and including a second adhesive layer applied to the polyester surface of the co-extruded film portion.
