  • #10 standard size fits business correspondence

#10 Side Seam Envelopes for High-Volume Mailing

These #10 side seam envelopes measure 4-1/8" x 9-1/2" and come in a hard box of 500. They are designed for businesses and offices that process large batches of correspondence. The white Digi-M stock provides a smooth finish optimised for inkjet printing.

Poly Window and C-Style Placement

Each envelope features a C-style poly window measuring 1-1/8" x 4-1/2", positioned 7/8" from the left edge and 1/2" from the bottom. This window allows recipient addresses to show through from the inserted document, removing the need to print directly on the envelope face. The poly material keeps the window clear during handling.

Remoistening Seal and Flat Storage

The flap-down design uses a traditional remoistening seal for closure. Two side seams run underneath the envelope body for structural integrity. The hard box keeps the stack flat and protected, preventing curl or damage that can cause feed issues in high-speed inkjet printers or inserters.

Questions about this item

Will the remoistening seal on these #10 envelopes lose adhesion after long storage?

The remoistening seal is designed to activate with moisture when needed; keeping the box sealed and stored in a cool, dry place preserves the adhesive until you are ready to mail.

What is the first limitation when printing large batches on the Digi-M surface?

The smooth Digi-M finish is optimised for inkjet absorption, so the practical limit is your printer's paper-tray capacity and ink drying time rather than the envelope stock itself.

How much heat or noise does the box add when sitting on a desk all day?

The packaged envelopes are passive paper products; they generate no heat, make no noise and draw no power while stored or during printing.
