Pressure Seal
Checks, Forms, & Direct Mail
Pressure seal is the most efficient way to produce mail-ready checks and forms without the need for an envelope. Through a unique folding and sealing process, a pressure sealer converts documents into self mailers. The whole process requires less parts, labor, and lead time to reach the mail stream. Pressure Seal checks and forms are secure and confidential making them a great fit for a variety of applications.
Examples of documents you can mail using pressure seal forms:
- Checks
- Utility bills
- Medical bills
- Transcripts
- Tax forms (W-2, 1099, ACA)
- Notices
- Invoices
- Statements
- PIN information
- Integrated Cards/Labels
- Direct Mail
How Does Pressure Seal Work?
First, pressure seal checks are imaged with a laser printer and compatible software. Next, the stub checks are loaded into a pressure sealer feed system (High volume systems run with a laser printer inline to a pressure sealer). During the folding process, the sealer machine aligns patterns of cohesive along the edges of the form. When the folded form passes through a series of sealing rollers that apply pressure, the cohesive is activated, creating a seal. The final product is a sealed mailer that is opened by tearing along the perforations.
