These #4 kraft self-seal bubble mailers combine a recycled golden kraft exterior with a 3/16" high-slip bubble lining that cushions contents during transit while allowing smooth, snag-free product insertion. The peel-and-stick closure forms a tamper-evident seal without additional tape or equipment at the packing station.

Well-suited for e-commerce fulfillment, retail distribution, publishing, and subscription box operations, these mailers handle flat and lightweight items — documents, photos, soft goods, and small accessories — that need reliable padding without the bulk of a rigid box.

Each case contains 70 mailers and ships via parcel carrier. The Freight Saver Pack format is sized to balance per-unit cost with manageable case weight, making it a practical stocking unit for operations running consistent daily outbound volume.
