Most listings describe a kraft paper outer surface combined with a polyethylene bubble lining. Some items list the material simply as polyethylene.
Product descriptions specify a 2/16‑inch bubble lining and repeatedly describe a bubble-lined wall construction to provide added cushioning and protection.
Some listings show both outside and inside sizes. Examples from results: outside 8.5" × 14.5" with inside 8.5" × 13.5", outside 8.5" × 12" with inside 8.5" × 11", and outside 9.5" × 14.5" with inside 9.5" × 13.5".
Descriptions call out an extra-smooth paper surface that’s good for handwriting, labeling, and stamping, and a paper covering that makes it easy to apply labels or stamps.
Some mailers are described as made with recycled materials and note that the paper and bubble components are recycled. The cushion-wrap copy states the roll may be recyclable in some programs but might not be accepted in all areas.
