What are Gummed Double Window Envelopes?
Gummed double window envelopes feature two transparent windows—one for the recipient's address and one for the sender's return address. The gummed seal is activated by moisture, ensuring a secure and tamper-proof closure. These envelopes are perfect for protecting sensitive documents while maintaining a professional appearance. The double window design saves time and minimizes the risk of address placement errors, making them an efficient choice for any mailing task.
These envelopes are particularly useful for businesses handling regular mailings such as payroll checks, account statements, and invoices. With pre-printed addresses visible through the windows, there's no need for manual labeling or additional address stickers. This small but impactful detail streamlines the mailing process, allowing staff to focus on more critical tasks.
Additionally, the gummed seal feature ensures that each envelope remains securely closed during transit. The moisture-activated adhesive creates a strong bond, preventing accidental openings and maintaining the confidentiality of your documents. This reliability makes gummed double window envelopes an essential tool for any business mailing operation.
The Benefits of Gummed Seal Envelopes
-
Secure Closure: The gummed seal activates with moisture, creating a firm bond that keeps contents secure. This feature ensures that sensitive information stays protected during transit.
-
Professional Presentation: The double window design eliminates the need for manual address labeling, saving time and reducing errors. A clean, professional appearance enhances your company's image.
-
Efficiency: Automating your mailing process with these envelopes helps streamline administrative tasks and improves productivity. Tasks that once required manual effort can now be completed quickly and consistently.
In addition to these core benefits, gummed seal envelopes are incredibly versatile. They're compatible with most office printers and mailing systems, making them easy to integrate into your existing processes. Whether you're mailing 10 or 10,000 envelopes, these products deliver reliable results every time.
Gummed vs Self-Seal Envelopes: Which Closure Is Right for You?
The difference comes down to how the flap seals. Gummed envelopes carry a strip of water-activated adhesive on the flap—wet it with a sponge, an envelope moistener, or the built-in moistening station on a mailing machine, press the flap down, and the gum bonds into the paper fibers as it dries. That bond is effectively permanent: the flap can't be peeled open and resealed without visible damage, which is why gummed seal envelopes remain the standard for checks and other sensitive financial mail. Self-seal envelopes, by contrast, use a pressure-sensitive adhesive under a peel-away strip—no moisture needed, just peel and press.

Choose gummed envelopes when you run mail through a folder-inserter or postage machine—the equipment moistens and seals each flap automatically, so the manual-sealing drawback disappears entirely and you keep the lower unit cost and longer shelf life. They're also the smarter buy if you order in bulk and store inventory between mailing cycles, since the dry gum doesn't degrade the way pressure-sensitive strips do. Choose self-seal when staff seal mail by hand and speed matters more than cost per unit. Many of our customers stock both: gummed envelopes for machine-processed payroll and statement runs, self-seal for day-to-day correspondence.
Gummed Seal Envelope Sizes We Stock
Most of our gummed seal envelopes come in the two standard business formats: #9 double window envelopes (3-7/8" x 8-7/8") for invoices, statements, and remittance mail, and #10 double window envelopes (4-1/8" x 9-1/2") for checks and thicker inserts. Both sizes position their windows to match documents printed from standard accounting software, so a tri-folded 8-1/2" x 11" sheet shows both addresses without labels.

Frequently Asked Questions
What are gummed envelopes?
Gummed envelopes have a dry, water-activated adhesive on the flap. Moisten the gum, press the flap closed, and it forms a permanent bond as it dries. Because the seal can't be opened and reclosed without tearing the paper, gummed seal envelopes are a trusted choice for mailing checks, payroll, and confidential statements.
What's the difference between gummed and self-seal envelopes?
Gummed envelopes need moisture to seal, cost less per unit, store for years, and run cleanly through mailing machines. Self-seal envelopes close with a peel-and-press strip—faster by hand, but slightly more expensive, and the adhesive has a shorter shelf life — typically 12 to 24 months depending on the closure style.
Can gummed envelopes run through folder-inserter machines?
Yes—this is where they excel. Folder-inserters and postage meters with sealing stations moisten and press each flap automatically, sealing thousands of envelopes per hour. If you process mail by machine, gummed seal envelopes are almost always the better value.
