ABSTRACT:
A heat-activatable adhesive article is provided. The article, preferably a tape, includes a substantially laterally stable heat recoverable carrier film having at least one surface comprising a recessed surface portion and a raised surface portion therein; and an adhesive layer in the recessed surface portion in an amount such that the adhesive does not extend above the raised surface portion thereby forming an exposed raised surface portion. In use, the carrier film recovers upon exposure to heat thereby allowing the adhesive in the recessed surface portion to contact a substrate. The heat-activatable adhesive article can be positionable, repositionable, or both.
