Open-Side Mailer Envelopes 4.625 x 8.875

These open-side envelopes measure 4.625 by 8.875 inches and are made from 24# white sulphite paper with a vellum finish. The SFI certified stock uses a side-seam construction and contains no window. Each box holds 500 envelopes suited for bulk mailing or office dispatch.

Spot Seal and Perforated Flap

A spot remoistening seal sits on the extended large flap, activated by moisture for a secure closure. Two side seams run underneath the flap to reinforce the envelope structure. The perforation allows the recipient to tear open the envelope cleanly without damaging contents inside.

Limits of Remoistening Adhesive

The spot seal requires moisture to activate and may not bond reliably in very dry or humid conditions. Paper-based envelopes can tear if overstuffed or handled roughly during automated sorting. The 24# weight provides standard durability but is not rated for heavy or bulky inserts.

Questions about this item

How do I confirm the envelopes are sealed correctly after moistening the spot seal?

Press the large flap firmly after applying moisture to the spot remoistening seal; the vellum finish and SFI certified white sulphite paper should show a clean bond along the two side seams under the flap.

What comes in the box and what must I supply separately?

The box contains 500 open side dual purpose mailer envelopes measuring 4.625 x 8.875 inches with 24# white sulphite paper, vellum finish, spot seal and perforation; you only need to provide moisture to activate the remoistening seal.

Which capacity should I choose for regular office mailing?

The box of 500 envelopes weighs 13 lbs and a full carton holds 2000 envelopes; select the 500 count box for typical monthly volume or the 2000 count carton for high volume mailing.
