Pressure Seal Mailers
Self-contained mail pieces that fold and seal without an envelope. Tamper-evident, cost-effective, and trusted by organizations sending billing, compliance, and marketing communications at scale.
How Pressure Seal Technology Works
Pressure seal mailers start as a single flat sheet. After printing, the sheet is folded and run through a pressure sealer that activates a cohesive coating on the edges, bonding the panels together. The result is a sealed, self-contained mail piece with tamper-evident perforated edges.
Recipients tear along the perforated edges to open the mailer, revealing the content inside. This sealed format creates curiosity and urgency that drives significantly higher open rates than standard envelopes.
