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.

Dual layer, pressure sensitive label sheets for ion deposition printing, use an adhesive on the back of the labels in the form of geometric patterns with narrow, adhesive-free bands between the geometric patterns. The patterns may be hexagonal or diamonds, for example, so that the edges of the die-cut labels will be held down; and the adhesive-free areas may be less than 1/16 inch, preferably in the other of 1/32 inch in width so that with the high pressures encountered in ion deposition printing, curl-free labels with high resolution printing is achieved.

A one piece mailer includes a standard size sheet which may be employed in laser printers or xerographic machines without special equipment and involves printing on one side only of the mailer. Stable adhesive material which will not run or contaminate the office machines, when it is subject to several hundred degrees heat is used for sealing. This adhesive is preferably water-activated. One embodiment includes a mailing sheet having an upper and lower half, with the upper half carrying the addresses and the message, and the lower half having windows which match the location of the addresses on the upper half of the mailer. The second embodiment involves a mailer having a first full sheet having an upper portion on which messages are printed, and a lower portion on which addresses are printed. On the rear side of the main sheet is a short partial sheet toward the bottom of the main sheet forming an envelope, and with a transverse strip of adhesive immediately above the envelope pocket to seal the envelope. Perforations extend across the main sheet just above the adhesive-coated strip, so that the message section may be separated from the envelope portion, and the message portion folded and placed within the envelope, and the envelope sealed. The third embodiment uses overlying message and envelope sheets, and is similar to the first embodiment in the use of windows in the envelope sheet which expose addresses from the folded message sheet.

An envelope assembly has rectangular form and cross-sectional thickness consistency for utilization with a sheet-feed printing apparatus. The assembly includes a first sheet having a centrally located transverse perforated tear line, and a second composite sheet having sections forming pockets, and strips forming sealing flaps toward the central tear line, so that the assembly has substantially the same thickness throughout. Thus, printing apparatus systems that have capabilities only for feed bin, paper tray or paper cassette feeding methods and are incapable of handling single business-size envelopes can be utilized for envelope printing with the present invention.
