The BUSINESS SOURCE BSN04469 is a No 9 business envelope designed for everyday commercial and office mailing. Built from 24 lb white wove stock, these envelopes feature a traditional diagonal seam construction and fully gummed flaps for reliable, clean closure. The No 9 size is a standard business format commonly used for inserting into No 10 outer envelopes or for direct mailing of standard correspondence. Each box contains 500 envelopes, making it a practical bulk option for high-volume mail rooms, offices, and shipping operations. The gummed flap eliminates the need for additional sealing supplies in routine mailing workflows.
These envelopes are suited for standard business correspondence, direct mail campaigns, statement mailing, and general office use. The white wove finish accepts inkjet and laser-printed addressing cleanly, and the diagonal seam pattern provides structural integrity during handling and transit. The No 9 format is widely used in both small office and high-volume commercial mail environments. Sold in a box of 500 units, this SKU is appropriate for procurement in office supply, mailroom, and packaging contexts.
Designed as a standard No 9 business envelope suitable for general commercial mailing, office correspondence, and use with standard desktop and high-volume envelope-inserting equipment that accommodates the No 9 format.
No tools or trade licensing are required for standard envelope use. Store in a cool, dry environment to preserve gum integrity on the flaps. Avoid exposure to humidity before sealing, as this can cause premature adhesion or gum degradation. For bulk mailing operations, verify compatibility with automated inserting or sealing equipment before committing to high-volume runs.
