Abstract
A staple-supporting strip for use with staples when binding documents together which affords removal and retention of the staples without detrimental affect on the document. The staple-supporting strip comprises two narrow layers of tough flexible polymeric material between about 0.1 and 0.15 mm thick. The strip may be colored or printed with a staple target area and a coating of a pressure-sensitive adhesive holds the bottom layer of the strip on the uppermost sheet of the documents to be stapled together such that the top layer may be peeled from the lower layer to unclench the staple legs during removal.
