Title: Method of making a sealable web or sheet product

Abstract: A web or sheet product is provided which is coated on at least a portion of its surface with a bond-enabling material for adhering toner particles on the surface of the sheet. The sheet product can be used as a mailer or confidential form which is sealed using toner particles as the adhesive. The bond-enabling material may be a polymer which is coated on the sheet as a liquid and then cured to form a film on the surface of the sheet. The bond-enabling material is resistant to melting or degrading when exposed to temperatures used for fusing toner particles, and additionally may act as a tie coat to enhance the adhesion of toner particles to the surface of the sheet. The bond-enabling material may be coated on the peripheral edges of the sheet, and toner particles are printed over the bond-enabling material on the peripheral edges of the sheet. The sheet is folded and sealed by the application of heat and pressure to the edges of the sheet.
