Standard #10 Business Envelopes

These #10 regular envelopes measure 4.125 x 9.5 inches and come in a box of 500. They feature a grooved white sulphite finish with SFI certification and two side seams under construction. The remoistening seal provides secure closure for everyday mailing tasks. Ideal for offices handling routine correspondence and bulk mailings.

High-Volume Office Mailing

Suits businesses sending invoices, statements or letters that fit standard #10 dimensions without a window. The grooved finish aids handling during machine insertion and manual stuffing alike. Not for senders needing window envelopes for address visibility or heavier stock beyond 24# weight. Buyers requiring coloured or security-tinted options should look elsewhere.

500-Count Box Capacity

A single box supplies 500 envelopes, while a full carton holds 2500 for larger operations. The 24# paper weight comfortably handles single-page letters and multi-page documents up to several sheets. Very thick packets or rigid inserts may exceed the flap seal strength or cause jams in high-speed inserters. Storage space for the 7 lb box should be planned accordingly.

Questions about this item

What size documents fit inside the 4.125 x 9.5 envelope?

Standard letter paper folded into thirds fits the #10 envelope, which measures 4.125 inches by 9.5 inches and holds A4 or US letter tri-folded sheets.

Does the grooved finish affect feeding through a laser printer?

The grooved white sulphite stock feeds reliably in most laser and inkjet printers; the SFI certified 24# paper weight reduces jams during high-volume print runs.

How can I confirm the remoistening seal activates properly?

Apply moisture along the flap, press firmly for several seconds, and verify the adhesive bonds across the full width; a secure seal holds the 500-count box weight when lifted.
