7" x 9" Stay Flat Envelope
Compact 7 x 9 rigid mailers sized for 5 x 7 prints, postcards, small art and paperback books. Peel and seal closure closes in seconds.
Description
The 7 x 9 stay flat envelope is sized for the smaller flat items that still need full bend proof protection in transit: 5 x 7 photo prints, 5 x 7 invitations, postcards, small art prints, paperback books and trading card slabs. This 7 x 9 rigid mailer is made from 420 GSM heavy duty cardboard that refuses to crease through carrier sorting machines, rough handling or weather, so smaller items arrive in the same condition you sent them.
Inside, the 6.96 by 8.96 inch cavity is sized to hold 5 x 7 prints with a matted border, 6 x 8 photos, paperback novels, small lookbooks, postcards and graded trading card slabs without slack. The 1.575 inch flap folds back enough for fast loading and the self-adhesive seal strip closes each 7 x 9 mailer in seconds without reaching for tape. The white, label-ready finish takes ink, stamps and shipping labels cleanly, which keeps small order fulfillment moving quickly. A built-in tear strip on the back gives recipients a clean opening that protects the contents during unboxing.
This is the right size for photographers shipping 5 x 7 portrait prints, wedding stationers mailing 5 x 7 invitation suites, Etsy sellers shipping small art prints and pet portraits, paperback book sellers, trading card sellers shipping graded slabs and PSA cards, and small ecommerce brands shipping postcards or promotional inserts. Every pack ships with 200 free Do Not Bend stickers, the cardboard is fully recyclable, and bulk pack sizes from 50 up to 200 bring the per mailer cost down meaningfully for businesses that ship the 7 x 9 stay flat envelope at higher volumes.
