Request Samples of U-Seal®

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 to be postal legal. U-Seal® does not bond as securely as pressure seal.
