Business double-window envelopes

These #10 white wove envelopes are sold in a 500-count box for high-volume office mailing. Blue security tinting shields invoice and cheque contents from view. Two poly windows position the sender and recipient addresses automatically. Gummed flaps close without moisture or tape.

Sustained office throughput

The 24 lb stock feeds reliably through laser and inkjet printers during long print runs. Window alignment stays consistent across the full box, reducing jam-related downtime. Security tint remains opaque even under bright sorting lights. Gummed adhesive holds firm in humid mailing rooms.

Replaces single-window or hand-addressed stock

Offices still printing address blocks on the envelope face save a full print pass per batch. The upgrade is worth it when monthly volumes exceed a few hundred pieces and privacy rules require tinted interiors. Not suited for oversized catalogues or non-standard document sizes.

Questions about this item

Do I need a printer to use the double-window layout on these #10 envelopes?

No printer is required; the two poly windows align with standard computer-generated invoices so the sender and recipient details show through automatically.

What size paper must I already have for these envelopes to work?

They are designed for standard 8-1/2 x 11 inch sheets, the typical output of most office printers and copiers.

Will the gummed flap seal reliably on older letterhead stock I still have on hand?

Yes, the fully gummed flap closes securely on standard 24 lb business paper, including older letterhead you may already use.
