#10 Poly Window Business Envelopes

These white sulphite envelopes measure 4-1/8" x 9-1/2" and feature a B-style poly window positioned to display recipient addresses. The diagonal seam construction and traditional remoistening seal suit standard business correspondence. Each box contains 500 envelopes for high-volume mailing tasks.

Window limits manual insertion

The poly window measures 1-1/8" x 4-1/2" and sits 7/8" from the left edge and 5/8" from the bottom. Address blocks must align with this fixed window area to remain visible. Documents with non-standard address placement or oversized address blocks will not work with this envelope format.

24# weight determines durability

The 24-pound sulphite paper stock provides a balance of opacity and stiffness for automated inserting equipment. Lighter contents move freely inside while the stock resists tearing during machine handling. Heavier multi-page statements may require a higher basis weight not offered in this product.

Questions about this item

Which envelope size and quantity should I choose for standard business mailings?

These are #10 size envelopes packed in a box of 500, the common choice for everyday invoices, statements and letters.

What does the 24 lb paper weight mean once the envelope is in use?

The 24 lb sulphite stock gives a crisp, professional feel that feeds reliably through laser and inkjet printers while keeping contents private.

How does the poly window work with address printing?

The B-style window measures 1-1/8" x 4-1/2" and sits 7/8" from the left and 5/8" from the bottom so a printed address shows through without extra labelling.
