#10 Window Envelope for Daily Mailing

The #10 window envelope is sized for standard business correspondence and ships in a box of 500. It suits offices, schools and home users who send invoices, statements or letters on a regular basis. The white sulphite stock carries SFI certification and a 92% brightness level for a clean, professional appearance.

Consistent Feed and Seal Reliability

The remoistening seal activates quickly and holds securely through automated inserting equipment or hand folding. Two side seams under construction keeps the envelope flat during high-volume runs, reducing jams in folder-inserter machines. Vellum finish resists smudging when documents are handled repeatedly before posting.

Poly Window and Flat Storage

A clear poly window protects the address panel from moisture and tearing while remaining readable by postal scanners. Flap-down orientation allows the boxes to stack neatly on a shelf or in a supply cabinet without curling. SFI certified sulphite fibre supports responsible sourcing for organisations with green procurement policies.

Questions about this item

How much heat does the poly window generate when the envelope sits in a printer all day?

The envelope is paper-based with a poly window and produces no heat during printing or storage.

What printer or inserter is required for the remoistening seal to activate?

Any standard office printer or inserting machine that feeds #10 envelopes will work; the seal activates with moisture from a moistener or dampener.

Will the 92% brightness vellum finish jam in older laser printers that struggle with textured stock?

The vellum finish feeds reliably in most legacy laser printers designed for standard #10 envelopes.
