These 7 1/4 x 12 inch kraft bubble mailers conform to the industry-standard #1 format and are built for operations that heat-seal outbound shipments. The recycled golden kraft exterior provides puncture resistance during transit, while the 3/16" high-slip bubble lining cushions contents and reduces friction during product insertion.

The multi-method closure design — compatible with tape, staple, or heat-seal equipment — makes these mailers a practical fit for e-commerce fulfillment, retail distribution, manufacturing shipping departments, and warehouse packing lines running a mix of manual and automated sealing processes.

Each case contains 100 mailers. The lightweight construction helps manage dimensional weight costs on small, flat, or padded-item shipments without reducing interior protection.
