Pressure Seal Stock Used In Checks and Forms

What is Pressure Seal & how does it work?

Pressure seal is a one-page self-sealing document that is mailed without an envelope. The forms can first be printed on an office laser printer and then fed through the Pressure Seal Folder/Sealer machine. Unlike other types of mailers that require heat or liquid for sealing, a pressure seal document is sealed through pressure. Folding aligns patterns of cohesive, which is applied to edges of the form during manufacturing. When the folded form passes through a series of sealing rollers that apply pressure, the cohesive is activated, creating a seal.
