ABSTRACT:
A file sheet dust cover comprises a plastic bag having a file-insertion type inlet opening, and flap joined to the plastic bag. The inlet opening allows insertion of a file sheet into the plastic bag. The flap is adapted to cover a portion of the file sheet projecting outside from the inlet opening, and a plurality of binder holes or cuts are provided in a bottom portion of the plastic bag such that when the file sheet is inserted into the plastic bag, the binder holes or cuts conform with a part or an entire part of a plurality of corresponding binder holes formed in the file sheet. A joined edge between the flap and the plastic bag is extended outwardly toward the inlet opening at opposite side ends of the plastic bag.
