ABSTRACT:
An envelope having a single peel-off backing sheet covering strips of pressure sensitive adhesive located along the sides of a panel of the envelope, which facilitates processing through automatic mechanical sheet feed printing equipment, laser printing equipment and feed through copy machines prior to folding the panel in order to form an envelope. Before the panel is folded, the panel, peel-off backing sheet, and peel-off strip attached to an adhesive strip on the envelope's closure flap provide a flat sheet of uniform thickness which can be easily processed through printing and copying equipment. After indicia is printed on the panel or copying is completed, an envelope may be formed by peeling the single backing sheet off the pressure sensitive strips, folding the envelope about a fold line located near the middle of the panel, and pressing the strips of pressure sensitive adhesive at the sides of the panel together so that a pocket is formed for holding a letter or other document. The strip covering the adhesive on the closure flap is then peeled off and the closure flap is folded about another fold line at the bottom of the flap allowing the adhesive on the flap to be pressed against the panel and the flap to be closed. The peel-off backing sheet preferably has a silicone coating on only one side thereof which allows a person to write or print on the other side of the backing sheet, allowing the sheet to be used as stationery or a letter.
