KingSeal: The Industry Standard in Pressure Seal Mailers

KingSeal is our pressure seal mailer—a one-part form that folds and seals to create a mail piece without requiring envelopes—the form itself also serves as the envelope. Unique to King Printing Solutions, our pressure seal is the industry leader, carrying the mark of quality and assurance. KingSeal Pressure Seal offers three key benefits: functionality, ease of use and security.



KingSeal mailers turn a single document into a ready-to-use, self-contained envelope. Your information is printed and securely sealed, eliminating the staging and inserting steps, as well as the envelope costs associated with traditional mailing. Select a standard format or customize a form and fold to meet all your pressure seal checks needs. We offer z-fold check paper, eccentric z-fold, c-fold, and v-fold as standards. But if you’re thinking outside of the box, talk to us if you are looking for something special. Mailers can be folded several ways, depending on the content of your message.  Click here to see folding options.


Ease of Use

Pressure seal paper means less waste and KingSeal works with virtually any printer. KingSeal Pressure Seal uses a dry cohesive that requires no water to activate the adhesive, which keeps your processing environment clean and reduces make ready and clean up time.
