Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
92 words
A pressure-sensitive composite which comprises: (a) a heat bondable plastic film; 5 (b) a backing attached to the film on one side thereof; 5 (c) a substantially continuous and uniform layer of a pressure-sensitive adhesive bonded to the side of the backing which is opposite the plastic film; and (d) a polymeric release liner attached to the adhesive layer opposite the side of the layer which is bonded to the backing, the liner having a melting point which is below the temperature at which the plastic 10 film is heat bondable. 10
Claim 2
Dependent Claim
92 words
A pressure-sensitive composite which comprises: (a) a heat bondable plastic film; 5 (b) a backing attached to the film on one side thereof; 5 (c) a substantially continuous and uniform layer of a pressure-sensitive adhesive bonded to the side of the backing which is opposite the plastic film; and (d) a polymeric release liner attached to the adhesive layer opposite the side of the layer which is bonded to the backing, the liner having a melting point which is below the temperature at which the plastic 10 film is heat bondable. 10
