WESTERN STATES #10 Poly Window Envelopes 24# White 500

SKU CH-86VF-3HZQ7

White 24# business envelopes with a poly window for address visibility, 92% brightness and diagonal seams, packed 500 per box

  • SFI certified paper supports responsible forestry
  • 92% brightness gives documents a clean professional look
  • Poly window shows recipient address without manual labelling
  • Diagonal seam construction adds strength for mailing durability
  • Box of 500 envelopes covers high-volume shipping needs

Standard #10 Size for Business Mail

These envelopes measure 4-1/8" x 9-1/2" and conform to the standard #10 commercial format used for everyday correspondence. The poly window is positioned 3/4" from the left and 1/2" from the bottom edge, measuring 1-1/8" x 4-3/4" to reveal recipient addresses printed on inserted documents. A traditional remoistening seal provides secure closure for invoices, statements and letters.

Replaces Hand-Addressed Plain Envelopes

Switching from standard non-window envelopes eliminates the need to manually address each piece or apply separate labels. The diagonal seam construction adds durability for automated inserting equipment, making the upgrade worthwhile for businesses processing high volumes of outgoing mail. The 24 lb sulphite stock feeds reliably through most office printers and copiers.

Window Alignment Limits Automation Speed

The fixed A-style window placement requires documents to be formatted so the address block aligns precisely within the 1-1/8" x 4-3/4" opening. Misaligned prints will show partial information or cut off text, requiring manual correction. The 92% brightness white sulphite paper provides good contrast for window visibility but offers no security tinting for sensitive contents.

Questions about this item

What size window does the #10 envelope have and where is it positioned?

The envelope has an A style window measuring 1-1/8" x 4-3/4" placed 3/4" from the left edge and 1/2" from the bottom edge.

How do I seal these envelopes and what is the common mistake?

Moisten the traditional remoistening seal on the diagonal seam flap and press firmly; the common mistake is applying too little moisture, which prevents a secure bond.

When will I need to replace the envelopes and what indicates it is time?

Replace the box of 500 when you run out; the white sulphite paper with 92% brightness and vellum finish remains stable in storage until used.
