Peel-N-Seal envelopes (also called peel-and-seal envelopes) have a protective paper liner covering a strong pressure-sensitive adhesive on the flap. To seal: peel off the release strip, fold the flap, and press — no moisture or water needed. Fast, clean, and professional. The adhesive creates a permanent, tamper-evident bond ideal for first-class correspondence, catalog mailings, and office use. See how the mechanism works in the interactive guide below.
