ABSTRACT:
A hinge for joining surfaces of sheet material comprises a strip of film/foam laminate positioned with a foam layer across the surfaces to be joined. The foam layer is tackified by heating and pressure is applied to the strip, thus heat sealing the strip to the surfaces. The hinge strip is preferably polyethylene film laminated to polyethylene foam and the surfaces to be joined may be polyethylene foam or a film/foam laminate.
The joined surfaces are not damaged or destroyed by the heat lamination. The foam layer of the hinge sealing strip is partially or substantially melted and the film upper layer of the heat sealing strip forms a permanent waterproof bond with the surfaces which it joins.
