Abstract
Conformable pressure-sensitive adhesive tapes which comprise a layer of polymeric foam in the backing and may be adhered firmly to a substrate and thereafter removed therefrom after only being stretched at an angle no greater than about 35° from the surface of the substrate. Articles for mounting an object such as a picture to a surface such as a wall comprising a pressure-sensitive adhesive tape of the invention are also described.
Claims3
A pressure-sensitive adhesive tape comprising a backing and a first layer of a pressure-sensitive adhesive composition coated on at least one surface of said backing, said backing having a thickness of at least about 30 mils, said backing further having a lengthwise elongation at break of from about 50% to about 1200%, said tape being capable of being firmly bonded to a substrate and thereafter being removable therefrom after being stretched at an angle no greater than about 35° from the surface of said substrate without said backing rupturing prior to the removal of said tape from said substrate and without leaving substantial pressure-sensitive adhesive residue on said substrate.
