Standard #6-3/4 size for everyday mailing

These white sulphite envelopes measure 3.625 by 6.5 inches and carry a 28-pound basis weight. The diagonal seam construction and remoistening seal provide reliable closure for letters, invoices and statements. SFI certification and 92 brightness indicate responsible sourcing and a clean professional appearance.

Suited for high-volume office mailing

Businesses that send large batches of correspondence will appreciate the 500-count box and vellum finish that feeds smoothly through laser and inkjet printers. Operations requiring a window for address visibility or a heavier stock for bulky inserts should consider alternative specifications.

28-pound basis weight determines feel and postage

Questions about this item

How do I seal the remoistening flap without it sticking prematurely?

Moisten only the gummed strip on the diagonal-seam flap, press firmly for a few seconds, and store the remaining 500 envelopes in the original box away from humidity to prevent accidental sealing.

When will the 28 lb sulphite paper start to yellow or degrade?

The SFI-certified 92% brightness white sulphite resists yellowing for years under normal indoor storage; replace the box only when the vellum finish feels rough or the remoistening gum no longer activates.

At what fill thickness does the diagonal seam risk splitting during mailing?

The 3.625 x 6.5 inch regular envelope handles standard letter folds; overstuffing beyond a few sheets stresses the diagonal seam first, so keep contents flat and avoid bulky inserts.
