U-Seal™ is a revolutionary new concept in self-seal mailing applications. Though similar to pressure seal in using Z, C and V fold sequences, U-Seal™ differs in many other areas. U-Seal™ requires only 10# of pressure to create a bond. This means you can literally hand seal your mailer. No offline equipment is necessary with minimal sealing pressure required; most folders on the market will seal the document.

In addition, continuous bursters can be used to create the mailed document. By utilizing a slitter/merger or plowfold unit, U-Seal™ can be designed in such a way that the slitting and bursting action creates the mailer as it leaves the burster. This means any post processing folder/sealers are no longer necessary. Also, since U-Seal™ is a light seal system, opening the document can be accomplished by peeling the document apart; therefore you do not loose any print territory to tear off margins.
