Abstract

A long length of one-sided or double-sided stretchable peelable adhesive tape from which a selected length of tape can be cut and has an integral pull tab for removal of the adhesive tape. The adhesive tape is available in strip or roll form. The article includes a length of stretch release adhesive tape. The adhesive tape has a first surface and a second non-adhesive surface. Along the longitudinal axis, the first surface has one or more adhesive areas and one or more non-adhesive areas. At least a portion of the non-adhesive area includes a series of tabs that can be removed from the substrate by pinching the tabs to a second non-adhesive area and stretching the tape.

Description

field of invention [0001] The present invention relates generally to a long length of one-sided or double-sided stretch-releasable adhesive tape that can be cut to a selected length and has an integral tab for stretching the tape from a substrate For removal. Background of the invention [0002] Stretch-release adhesive tapes are a new class of high-performance pressure-sensitive adhesive tapes that provide strong adhesion and clean removal without surface damage. This stretchable peelable adhesive tape can be used for various assembling, connecting, fixing and installing purposes. [0003] Adhesive tapes which can be cleanly removed from a surface by stretching are known from prior art patents. For example, US Patent 4,024,312 to Korpman discloses a highly conformable adhesive tape comprising an adhesive tape laminated with an adhesive layer on a highly extensible and elastic backing film. The backing film has an elongation at break in the length direction of at least ab...
