摘要：A removable adhesive tape comprising a highly extensible and substantiallyinelastic backing and a layer of pressure-sensitive adhesive. The backing has a high tensilestrength, has a lengthwise elongation at break of at least about 150% with less than
about 50% elastic recovery after stretching. The adhesive can be a normally tacky andpressure-sensitive adhesive and is coated on at least one surface of the film backing. Theadhesive is preferably highly extensible, does not separate from the backing duringstretching, and has higher cohesion than adhesion to any suitable substrate. After beingapplied to a substrate, the adhesive tape of the present invention becomes firmlybonded, but can be easily removed without damaging the substrate by simply stretchingit in a direction substantially parallel, i.e., less than about 35°, to the surface of thesubstrate.
