WESTERN STATES #10 Regular Envelope 24# Bright White 96% 4.125x9.5 Box 500

Standard #10 Business Envelope

The Western States #10 regular envelope measures 4.125 x 9.5 inches and uses 24 lb bright white sulphite paper rated at 96 percent brightness. The SFI certified vellum finish suits everyday correspondence, invoices and direct-mail pieces. Each box contains 500 envelopes with a remoistening seal and diagonal seam construction. Acid-free stock helps preserve documents over time.

Build and Mailing Integration

The standard #10 size fits common folding machines, inserters and desktop printers without adjustment. Full-seal flaps close securely on high-speed inserting lines and resist opening in transit. The 500-count box aligns with typical mailing runs, while the 2500-count carton supports larger campaigns. No window means full design freedom for printed addresses or graphics.

Sustained Use Characteristics

Vellum sulphite stock feeds cleanly through laser and inkjet devices during long print runs without excessive curl or jams. The 24 lb weight holds up to repeated handling in sorting equipment while keeping postage costs predictable. Remoistening adhesive activates reliably across humidity ranges, maintaining seal integrity from the first envelope to the last in the box.
