Business Mailing Envelopes

These #9 cellophane window envelopes measure 3.875 x 8.875 inches and come in a box of 500. They are designed for offices that send invoices, statements or cheques through the post. The white sulphite stock carries SFI certification and a 92 brightness rating for a clean, professional appearance. The diagonal seam construction adds strength for automated inserting equipment.

Window Alignment

The cellophane window measures 1-1/8 x 4-3/4 inches and sits 3/4 inch from the left edge and 1/2 inch from the bottom. This placement matches standard cheque and statement layouts so the recipient address shows through without manual adjustment. The transparent film protects the contents while keeping the address legible during handling.

High-Volume Durability

Each box weighs 6.5 lbs and contains 24 lb paper with a vellum finish that resists curling in humid conditions. The remoistening seal activates reliably after storage, and the diagonal seam holds firm during continuous feeding through folder-inserter machines. A full carton holds 2500 envelopes for departments that process large daily mail runs.
