Pressure seal checks and forms are self-mailing documents that do not require envelopes. These pressure seal items have a built-in adhesive that, when folded and sealed, creates a secure closure. Ideal for high-volume mailing, pressure seal checks and forms are commonly used for payroll checks, invoices, statements, and marketing materials. They offer a cost-effective solution for businesses looking to streamline their mailing processes and reduce the need for envelopes and additional labor. Pressure seal checks and forms are designed to be compatible with automatic folding and sealing machines, making them efficient and convenient for large-scale mailings.
