Suitable for high-volume mailings
These white sulphite envelopes come in a box of 500 and are designed for machine inserting. The open-side format with two side seams under feeds reliably through inserting equipment. They suit offices that process large batches of statements, invoices or direct-mail pieces.
Check your inserting machine specifications
Verify that your equipment accepts 6 x 9-1/2 open-side booklet envelopes with side-seam construction. Confirm the machine can handle 24 lb sulphite stock and the vellum finish without feeding issues. Ensure the side-seam-under orientation matches the folder and inserter settings.
Consistent feeding over long runs
The 92 brightness white sulphite maintains stiffness and surface quality across extended print and insert cycles. Side seams under reduce edge curl that can cause jams during continuous operation. Vellum finish resists marking and static buildup when envelopes move through rollers at production speed.
