Pressure sealers fold and seal compatible pressure-seal forms into a finished self-mailer. Choose the machine from the form backward: sheet size, fold pattern, adhesive layout, normal batch, busiest daily volume, and the way forms arrive at the sealer.
Bring printed forms and a finished sample to the evaluation. The fold and adhesive pattern must match the machine setup and the required mailpiece.
Size the machine around the real workload
Record average and peak daily volume, batch size, changeovers, required fold patterns, form sizes, and operator availability. A desktop unit can suit intermittent batches. A production system is easier to justify when long runs, frequent jobs, or upstream print volume would leave a smaller machine as the bottleneck.
If the sealer must connect to another process, define the handoff, counting, reject handling, and downtime plan before choosing in-line or offline production.

Pressure sealer FAQ
What is a pressure sealer used for?
It folds and seals compatible forms into self-mailers such as checks, notices, and statements.
Do pressure sealers use envelopes?
No. The printed form becomes the mailpiece after folding and sealing.
How do I choose a pressure sealer?
Match the form size, fold pattern, adhesive layout, batch size, peak daily volume, and upstream print workflow.
Can I run ordinary paper through a pressure sealer?
The job requires a compatible pressure-seal form and adhesive pattern. Test the actual form before purchase.
Should the machine run in-line or offline?
Use the print workflow, downtime risk, job mix, and verification needs to choose the handoff.
