kraft paper bubble mailers

These mailers feature a kraft paper exterior (described as durable and recycled) and an inner polyethylene bubble lining (polyethylene sheet bubble wrap) for padding.

The listings specify a 2/16‑inch bubble lining, which is equivalent to 1/8 inch.

Weights vary by listing and size, ranging from about 0.19 ounces up to about 2.2 ounces.

They use an extra‑smooth kraft paper surface (paper covering) that’s described as suitable for handwriting, applying adhesive labels, and affixing postage stamps.

Example outside dimensions shown include 8.5"×14 (some listings 8.5"×14.5), 8.5"×12, and 9.5"×14.5. The corresponding usable interior/inside spaces are listed at about 8.5"×13.5, 8.5"×11, and 9.5"×13.5, respectively.

Common pack counts shown are 10, 25, 50 and 100 units.

They’re described as suitable for papers, documents and letters; photographs and small flat artwork; and small items such as jewelry, stones, coins and buttons.

The usable interior is slightly smaller than the outside dimensions—typically about 1 inch shorter in length. For example, an outside size listed as 8.5"×14.5" often shows an interior of about 8.5"×13.5", and an outside 8.5"×12" corresponds to an interior around 8.5"×11".
