Our take on the Staples 11.25" x 15" Self-Sealing Bubble Mailer, #5, 25/Carton ST56649B

These are #5 kraft bubble mailers sized 11.25 by 15 inches, sold 25 to a carton. The self-sealing peel-and-stick strip closes each mailer without tape, and the bubble lining cushions small to mid-size items in transit. They suit home sellers, small offices and anyone shipping books, clothing or accessories. Compared with plain poly mailers they cost more but protect fragile contents; compared with padded paper envelopes they are lighter and cheaper to post.

  • Light enough to keep postage costs down

Questions and answers

What can fit in a #5 bubble mailer?
The 11.25 by 15 inch size holds a hardcover book, a folded shirt, a pair of shoes or a small boxed item. Measure anything thicker than about an inch against the bubble lining before sealing.
Do I need tape to close these mailers?
No. Peel the backing off the adhesive strip and press the flap down. The seal holds on its own, though heavy contents may warrant a strip of tape for extra security.
Are these mailers waterproof?
No. The kraft paper resists light moisture but is not waterproof. For rain-prone routes, use a poly mailer or add a plastic sleeve inside.
How do these compare with poly mailers?
Bubble mailers cost more and weigh more, but they cushion fragile items. Poly mailers are lighter and cheaper for soft, non-fragile goods.
Can these go through USPS, UPS or FedEx?
Yes, they are accepted by major carriers as padded envelopes. Check the thickness against each carrier's large-envelope limits if you stuff them full.
