Abstract
A system and method for constructing sealed printed packages and one-piece mailers provides fixedly applying printing toner to predetermined locations upon a first part of a face of a printable sheet. The sheet is then folded so that a second part of the face overlies the first part which includes the locations having the toner thereon. The toner is then sealed so that the first and second parts are joined together. The toner may comprise a heat activated xerographic powdered toner. The second part of the face may include toner at locations that overlap the toner upon the first part and sealing may involve preheating of the toner prior to folding and then applying additional heat and pressure to the toner by means, for example, of rollers subsequent to folding. The sheet may then be cooled.
