Double-window invoice envelopes

Business Source 36681 envelopes are designed for high-volume mailing of computer-generated invoices and statements. Each box contains 500 white No. 9 envelopes with two poly windows positioned for return and mailing addresses. The inside tint adds privacy for confidential documents. They suit offices that process large batches of standard letter-size paperwork.

Self-seal closure and privacy

The self-sealing design uses a unique double flap that prevents the gum from sticking before use. Simply raise the lower flap and press to close without moisture. The 24 lb stock and poly windows keep contents secure during handling. This construction reduces preparation time and helps maintain a professional appearance for outgoing mail.

Bulk supply for daily mailing

A 500-count box provides a long-lasting stock for continuous invoice runs. The envelopes work with most standard 8-1/2" x 11" printed forms and fit common postage meters. No special equipment is required beyond a standard printer. They free up staff time otherwise spent moistening and sealing individual envelopes.

Questions about this item

How do I seal the Business Source 36681 envelope correctly, and what step do people often miss?

Raise the lower flap first, then press firmly to activate the self-seal adhesive; skipping the lower-flap lift leaves the gum protected and the envelope unsealed.

When will the 24 lb paper or poly windows need replacement during regular office use?

The box contains 500 envelopes; replace the entire box once the supply is exhausted, as individual envelopes are single-use and not designed for reuse.

What is the first limitation that appears when processing high volumes of invoices with these No. 9 envelopes?

The fixed double-window positions (top window 1-3/16" x 3-1/2", bottom window 1" x 4") require invoices to align precisely; misaligned print runs will show address data outside the windows immediately.
