Peel & Seal Envelopes

Key Summary:

This guide explores the benefits, styles, and applications of Peel & Seal envelopes.
 From business to event use, these self-sealing envelopes offer security, ease of use, and a polished look across various sizes and finishes.
 We’ll cover dimensions, comparisons, types, use cases, and how to choose the perfect peel-and-seal envelope for your needs.

Peel & Seal envelopes are available in a wide range of sizes, with some of the most popular including #10 (4 1/8 x 9 1/2 inches), A7 (5 1/4 x 7 1/4 inches), and 9 x 12 inches. These options cover everyday correspondence, invitations, and document shipping. The added adhesive strip across the flap makes sealing quick, clean, and tamper-resistant—no moisture required.

Compared to traditional gummed flaps or clasp closures, peel-and-seal envelopes offer a mess-free, secure solution. They are ideal for high-volume mailing or events where sealing multiple envelopes quickly is a priority. Unlike clasp or tuck flaps, Peel & Seal styles eliminate the need for additional tools or tape while maintaining a professional finish.

• Standard Business Envelopes with or without address windows

Example:

A bride sending out 150 formal wedding invitations can save time and ensure every envelope stays sealed during mailing using gold foil-lined A7 Peel & Seal envelopes.
