SKU CH-GSM7-MHPXY

Standard #10 business envelopes in 24 lb white sulphite with 92% brightness, vellum finish, side-seam construction and no window, box of 500

  • Standard #10 size fits everyday business mail
  • 24 lb sulphite stock gives a crisp professional feel
  • 92 % brightness ensures clean print contrast
  • Side-seam construction adds strength for machine inserting
  • Box of 500 envelopes covers high-volume mailing needs

Standard #10 Business Envelopes

These white sulphite envelopes measure 4-1/8 by 9-1/2 inches and come in a box of 500. They suit offices, schools and home users who send invoices, letters or statements on a daily basis. The 24 lb stock feeds reliably through most desktop printers and copiers. Buyers who need padded, windowed or oversize mailers will not find those features here.

SFI-Certified 92 Brightness Vellum Finish

The paper carries SFI certification and delivers 92% brightness with a vellum surface that resists feathering. Two side seams under construction add strength at the edges during automated insertion. The traditional remoistening seal closes securely without tape. No windows, security tint or peel-and-strip adhesive are included.

Easy Load-and-Print Setup

Flap-down orientation lets you stack the envelopes directly in a standard paper tray. Most jams occur when the tray guides are left too loose or when humidity curls the flap. Store the soft box flat and reseal it after opening to keep the stock flat. Heavy-coated or textured letterhead may increase the risk of double-feeds.

Questions about this item

How long will the remoistening seal stay effective in storage?

The traditional remoistening seal remains usable for years when the box is kept in a cool, dry place away from humidity.

What limits how many envelopes I can run through a high-volume inserter before jams increase?

The 24 lb sulphite stock and side-seam construction set the practical throughput ceiling for most desktop inserters.

Does the 92 % brightness white paper reflect enough heat to raise the temperature inside a sealed mailing machine?

No, the paper’s thermal mass is negligible and the vellum finish does not trap measurable heat during continuous operation.
