These #4 kraft bubble mailers feature a recycled golden kraft paper exterior paired with a 3/16-inch high-slip bubble lining, delivering cushioned protection in a lightweight, parcel-friendly format. The interior measures 14 1/2 x 9 1/2 inches, accommodating flat and semi-rigid items without adding unnecessary package weight to outbound shipments.
The high-slip lining accelerates product insertion on busy pack lines, making these mailers well suited for e-commerce fulfillment centers, retail distribution operations, subscription box services, and direct-to-consumer shipping environments where throughput and per-unit cost both matter. Closure is compatible with heat seal, tape, or staple, giving packaging stations the flexibility to match existing equipment and workflows.
The heat-seal closure option produces a clean, tamper-evident finish appropriate for consumer-facing shipments. Each case contains 100 mailers. The kraft construction keeps individual package weight low, supporting cost management on both actual-weight and dimensional-weight parcel billing.
