The listings show outside dimensions from small envelopes (about 4" x 8") up to large mailers (around 14.25" x 20"). A 12 in. x 60 ft. cushioning roll is also listed as a bulk wrapping option.
Listings include kraft paper mailers with bubble lining and plastic-based options such as polyethylene and polypropylene.
Most padded mailers use a self-adhesive, fold-over seal. A cushioning roll has no closure since it’s sold for wrapping rather than sealed shipping.
They use bubble-lined padding — some listings note multilayer bubble walls and specify bubble-lining thickness in product details.
Inside usable space is slightly smaller than outside dimensions. Examples from the listings: outside 9.5" x 14.5" with inside 9.5" x 13.5", and outside 4" x 8" with inside 4" x 7"—often about an inch difference in one dimension.
Some listings state mailers are recyclable or contain recycled content. Several notes advise that local recyclability can vary and that some stores accept plastic-bag–type materials for recycling.
