Abstract
A staple-supporting strip for use with staples when binding documents together which affords removal and retention of the staples. The staple-supporting strip comprises a narrow elongate strip of tough polymeric material between 0.1 and 0.15 mm thick. The strip may be colored or printed with a window identifying the area for reception of the staples. A narrow coating of a low-tack pressure-sensitive adhesive facilitates positioning of the strip on the uppermost sheet of the documents to be stapled together.
