Abstract
A double sided tape has repositional with adhesive associated with a first face. The tape may be in the form of a roll, and the adhesive on the second face may be either repositional or permanent. In order to facilitate rolling, a release liner is provided on one of the adhesive faces. The tape may have perforations, notches, or slits along its length to facilitate detachment of predefined lengths of the tape, as from a dispenser. A tie coat may be applied to each of the faces of the substrate before the adhesive is applied. One face of adhesive can be readily applied to one object (e.g., a shelf or a piece of paper), while the repositional adhesive is then available to removably attach that object to another object (e.g., another piece of paper).
