WESTERN STATES

WESTERN STATES #10 Poly Window Envelopes 24# White Blue Tint Box 500

SKU CH-R8XT-RHC1E

Standard #10 business envelopes with a poly window and blue security tint hold 500 pieces for high-volume invoicing and statements

  • SFI certified paper supports responsible forestry
  • 92% brightness gives crisp print contrast
  • Blue Wesco tint blocks document visibility
  • Poly window aligns with QuickBooks address fields
  • Box of 500 envelopes covers high-volume mailing

Standard #10 Business Envelope

These #10 envelopes measure 4-1/8" x 9-1/2" and are built from 24 lb White Sulphite paper with a vellum finish. The poly window sits 3/4" from the left edge and 1/2" from the bottom at 1-1/8" x 4-3/4". A diagonal seam construction and blue Wesco inside tint complete the design. Each box contains 500 envelopes for high-volume mailing needs.

Capacity and Headroom

The 500-count box supports daily invoice batches, monthly statements and recurring QuickBooks mailings without frequent reordering. The 92% brightness and security tint keep printed addresses legible through the window while shielding confidential data inside. Very large inserts or rigid documents may exceed the standard #10 dimensions and require a larger envelope format.

Build Fit and Clearance

The diagonal seam and poly window align with most laser and inkjet printers for automated addressing workflows. The blue tint eliminates the need for separate security liners when mailing checks or sensitive financial documents. Standard #10 dimensions fit common postage meters and folder inserters, while the 24 lb stock feeds reliably through office equipment. Buyers needing peel-and-seal closure or custom printed branding should specify those options separately.

Questions about this item

Will the 1-1/8" x 4-3/4" poly window align with standard QuickBooks invoice layouts?

Yes, the window is positioned 3/4" from the left edge and 1/2" from the bottom edge, matching the standard alignment used by QuickBooks and similar accounting software for window envelopes.

How can I confirm the blue security tint is effectively blocking the view of the contents?

Hold a sealed envelope up to a strong light source; the 92% brightness white sulphite paper combined with the Blue Wesco inside tint should prevent any legible text from showing through the non-window areas.

Does the box of 500 envelopes include moisture-activated adhesive on the flap, or do I need separate sealing supplies?

The diagonal seam envelopes come with standard gummed flaps that activate with moisture; no tape, labels, or additional sealing products are required for normal mailing use.
