5. The tape of claim 1 further defined in that said adhesive is spaced from a point beginning from about 0.005 inch (0.1 mm) to about 1/4 inch (6.35 mm) from each edge of said substrate to a point from about 0 inches (0 mm) to about 1/4 inch (6.35 mm) from the outside circumference of said holes whereby a portion of each edge of the substrate and the center portion of the substrate are adhesive free.

6. The tape of claim 1 further defined in that the adhesive coating ranges in thickness from about 0.0005 inch (0.01 mm) to about 0.01 inch (0.25 mm).
