Abstract
A variable size envelope with a single closure flap that may be selectively folded along either of two different fold lines to provide two different sizes of envelopes. A pocket for holding papers or other documents may be formed by a single rear panel or two rear panels joined together. The height of the closure flap is preferably equal to the height of the panels so that the envelope when folded into a smaller size presents a flat envelope of uniform thickness which may be processed through automatic mechanical printing equipment, laser printing equipment and copying machines, then unfolded and later used as a larger size envelope. Adhesive strips are provided on the closure flap for the purpose of sealing the envelope. The adhesive used for the strips is preferably a stable, water-activated, or moisture-activated adhesive, which is not significantly affected by either heat or exposure to high humidity facilitating use of the envelope during laser printing or xerographic copying. A stable, pressure-sensitive adhesive covered by a peel-off strip may also be used for the adhesive strips on the closure flap.
