bubble mailers 8 5 x 11

Many listings show an outside size of 8.5" x 12" and a usable (inside) size of 8.5" x 11".

Listings describe either kraft paper exteriors with bubble (polyethylene) lining or all-polyethylene (plastic) construction; both kraft with polyethylene lining and full polyethylene versions appear in the listings.

Most listings specify a self-adhesive (self-seal) closure with a tamper-evident adhesive flap.

Descriptions list bubble padding examples such as "2/16 inch" bubble lining and "3/16 inch" high-quality bubbles.

Listings offer various pack sizes, commonly 1, 5, 10, 25, and 100.

Kraft-lined mailers have smooth paper surfaces suitable for handwriting; poly mailers accept ink, stamps, and self-adhesive labels easily. One listing also notes a plain finish that provides a clear area to write addresses.
