ABSTRACT:
A kit for shrink wrap framing includes a light rigid backing board having one face coated with positionable pressure-sensitive mounting adhesive and a release sheet, a rectangular shrink-wrap envelope about 1/4 inch larger than the backing board on all four sides, with a 1-inch flap along one short side coated with pressure sensitive adhesive and a release strip, plastic corner reinforcements and double-faced foam suqares or foam tape. The user peels the release sheet from the face of the board, presses the artwork to be mounted against the exposed adhesive area, inserts the plastic corner reinforcements into the four corners of the board, inserts the board into the shrink film envelope, removes the release paper frpom the envelope flap, seals the envelope flap and exposes the assembly to heat, such as from a gun-type hair dryer until the shrink film is tightly wrapped around the enclosed assembly.
