Business Source BSN36681 Double Window Envelope No 9 Box of 500

Product Description

The BUSINESS SOURCE BSN36681 is a No. 9 double window envelope designed for high-volume invoice and statement mailing applications. Measuring 3-7/8 by 8-7/8 inches and made from 24 lb white paper, each envelope features two clear poly windows that eliminate the need to hand-address outgoing mail. The top window measures 1-3/16 by 3-1/2 inches, positioned 3/8 inch from the left and 2 inches from the bottom. The bottom window measures 1 by 4 inches, positioned 3/8 inch from the left and 1/2 inch from the bottom. A self-sealing closure requires no moisture, and an inside tint provides privacy for enclosed documents.

These envelopes are suited for offices, billing departments, and accounts payable operations that process large quantities of outgoing correspondence. The double window design aligns with standard 8-1/2 by 11 inch invoices, statements, and remittance documents so both the return address and recipient address show through without additional labels or printing. The self-sealing double flap design prevents the gum from sticking before use, making bulk processing faster and more reliable. Each box contains 500 envelopes, supporting continuous-run mailing workflows.

Installation Notes

Store envelopes flat in a cool, dry environment to prevent the self-sealing adhesive from activating prematurely. When inserting documents, verify that both address blocks are fully visible through the corresponding poly windows before sealing. Peel the protective strip and press the flap firmly for a secure closure. No moistening device or additional sealing equipment is required.
