ABSTRACT:
A protective binder for storing and protecting printed or written material normally contained on multiple pages of unbound materials. The binder includes a unitarily formed and foldable semi-rigid member, preferably made of a thermo-formed polypropylene material. The foldable member has a front cover, a back cover, and a rear edge section. Hinge portions are unitarily formed between the front cover and the rear cover and the rear edge section, thereby flexibly interconnecting the front and rear covers to the rear edge section. A clear, elongated, flexible tape is bonded along a central section thereof to the rear edge section. An adhesive is provided along interior portions of the tape for securement to the front and rear pages of materials to be bonded or secured in place within the binder. The tape is free of any adhesive on the outer surfaces thereof which are adjacent the front and rear covers. The pages are securely received by the tape for storage between the front and rear covers.
