A splicing tape for splicing a leading edge portion of the outer turn of a roll of sheet material to a second sheet material. A typical application is to join the outer turn of a replacement roll of paper to the end of depleted roll of paper while the paper remains in motion through some handling apparatus. The splicing tape comprises a first tape component (12), and second tape component (20), and a layer of adhesive separably joining the first and second tape components. The first tape component includes a first backing (14), a first layer of adhesive (16) on a first surface of the first backing, and a first barrier layer (18) on a second surface of the first backing (14). The second tape component includes a second backing (22), a second layer of adhesive on a first surface of the second backing, and a second barrier layer (26) on a second surface of the second backing. Alternatively, the splicing tape may include only one barrier layer between the joining adhesive layer and one of the first and second backings. The layer of adhesive separably joins the first and second tape components at their respective barrier layers. Also disclosed are methods of manufacture and methods of use of the inventive splicing tape.
