White Kraft Envelopes for Bulk Mailing

These 9 by 12 inch open side booklet envelopes arrive in a box of 500. The 28 pound White Kraft stock carries SFI certification and an 84 brightness rating with a Vellum finish. A poly showcase window measures 7 by 9-3/4 inches positioned 1-1/8 inches from the left and 1 inch from the bottom. Side seam construction and a remoistening seal complete the design.

Upgrade from Standard Window Envelopes

The larger showcase window and heavier 28 pound paper replace lighter stock when documents need more visibility and a sturdier feel. The jump is worth it for high-volume statement or brochure runs where presentation matters and the Vellum finish adds a tactile quality. Side seams run the full height to support thicker inserts without splitting.

Suits Offices Sending Multi-Page Documents

This box suits mailrooms that process 500 pieces at a time and need the larger window to show addresses on folded sheets. Buyers who require laser printer compatibility should look elsewhere because the stock is not laser compatible. Anyone needing a smaller quantity or a different window position will need another product.

Questions about this item

Will the 9 by 12 inch open-side envelope with its 7 by 9-3/4 inch poly window fit standard letter inserts?

Yes, the envelope measures 9 by 12 inches and the poly window is 7 by 9-3/4 inches, positioned 1-1/8 inches from the left and 1 inch from the bottom, so standard letter pages fit behind the window.

How do I seal the remoistening flap on the side-seam booklet envelope without tearing the vellum-finish kraft paper?

Lightly moisten the flap adhesive, press firmly along the side seam for a few seconds, and avoid over-wetting the 28# White Kraft stock to prevent curling.

When should I replace the box of 500 SFI-certified envelopes if the remoistening seal loses tack?

Store the box in a cool, dry place; if flaps no longer seal after moistening, the adhesive has aged and the remaining envelopes should be replaced.
