Abstract
A cover for protecting and supporting a plurality of sheets bound together with a pressure-sensitive adhesive tape and bound to the cover by the tape. The cover has a binding area and a protective coating in that area where the binding tape has an adhesion force of between 200 and 700 grams per 1.27 cm width of tape according to a standard adhesion peel test. The coating may be an actual coating of low adhesion material, a film, a coated plastic film, or the cover material. The cover may include a sheet folded centrally, a truncated cover to afford attachment of a separate cover sheet, or the cover may be formed to cover only the front or back of the documents to be bound thereon.
