kraft bubble mailer

Interior/useful space examples listed include 8.5×11, 8.5×13.5, and 9.5×14.5, reflecting the different outside sizes shown in listings.

They typically combine a kraft paper exterior with a polyethylene bubble lining; some listings also note recycled paper or recycled bubble materials.

They use a self-adhesive, self-seal flap designed to provide a tight, tamper-evident closure.

Multiple descriptions list a 2/16-inch bubble lining and refer to multilayered or air-cell bubble construction for cushioning and protection against impacts.

Package quantities shown include 10, 25, 50, and 100. Listed per-mailer weights range from about 0.19 ounces up to about 2.2 ounces.

Descriptions note an extra-smooth kraft surface and paper covering that make them easy to write on, to apply labels to, and to stamp.
