Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
110 words
An anisotropic film laminate pressure-sensitive adhesive tape comprising a film laminate having a first face and a second face said film laminate comprising a continuous elastomeric core layer and at least one continuous inelastic skin layer or uniaxially oriented plastic, the film laminate being substantially inelastic in, the direction of orientation of said at least one skin layer said skin layer being unoriented in a direction transverse to said direction of orientation such that the laminate is extensible in said transverse direction, said laminate on at least one of said first face or said second face further comprising a pressure-sensitive adhesive layer so as to form a pressure-sensitive adhesive tape.
Claim 2
Dependent Claim
