Product Identity

These are white sulphite catalog envelopes measuring nine by twelve inches with a poly window and center seam construction. They are sold new in boxes of five hundred and suit offices that send flat documents such as invoices, statements or brochures through the mail.

Compatibility Check

Verify that your inserting equipment or folder can handle a 28 pound stock with an open end flap and a window positioned two and a half inches from the left edge and five inches from the bottom. The remoistening seal requires moisture to activate so ensure your process includes a wetting station or manual sealing step.

Environmental Performance

The SFI certified sulphite paper has a 92 brightness rating and a vellum finish that feeds smoothly through most desktop printers and high volume inserters. Each box weighs twenty two pounds so plan storage shelf capacity and lifting ergonomics accordingly for bulk orders.

Questions about this item

What comes inside the box and is any sealing supply sold separately?

The box contains 500 white sulphite catalog envelopes measuring 9 by 12 inches with a poly window and a remoistening seal already applied to the flap. No extra adhesive or sealing material is required.

Which capacity should I choose if I need a single bulk pack for high-volume mailing?

The only pack size offered is the 500-count box, which also serves as the shipping carton weight of 22 lbs, so one box covers the full quantity in a single order.

How does the 28 lb paper weight perform when the envelope runs through a folder-inserter machine?

The 28 lb sulphite stock with vellum finish provides enough stiffness for reliable feeding in folder-inserters while the centre seam and open-end design keep the envelope flat during high-speed insertion.
