These #4 kraft bubble mailers combine a recycled golden kraft paper exterior with a 3/16" high-slip bubble lining, delivering cushioned protection without meaningfully adding to shipment weight. A peel-and-stick self-seal lip forms a tamper-evident bond with no tape or heat equipment, and a built-in pull tear strip lets recipients open packages cleanly without scissors or tools.

The lightweight profile makes these mailers a practical choice for e-commerce fulfillment, retail distribution, subscription box operations, and direct-to-consumer shipping where dimensional weight and packing speed are both priorities. The bubble lining handles moderate impact protection for items that don't require a rigid corrugated enclosure — apparel, documents, soft goods, and similarly flat or flexible products.

Mailers are made from recycled kraft paper with a 3/16" bubble interior. Each pack contains 25 mailers, suited for operations that prefer smaller replenishment quantities over full-case purchasing.
