ABSTRACT:
A folder insert is provided for a bifolding folder or ring binder to expand the capacity thereof. The folder insert is formed of a single sheet of flat stock folded to form at least one rectangular support panel with opposing faces and at least one pair of separate pocket panels extending from the support panel. The pocket panels are folded across portions of the support panel against both of the opposing faces thereof and are anchored to the support panel along the bottom edge and at least one of the lateral edges of the support panel. The same sheet of flat stock includes an attachment flap extending along one of the lateral edges of the support panel. The attachment flap allows the folder insert to be attached inside a folder. In an alternative embodiment the sheet of flat stock forms a rectangular support panel and a single pocket panel folded across a portion of the support panel and is anchored thereto along the bottom edge and both of the lateral edges. The support panel and pocket panel form a pocket therebetween which may be provided with accordion folds to permit expansion.
