These #3 kraft self-seal padded mailers feature built-in fiber cushioning that expands during transit to absorb impact, eliminating the need for supplemental dunnage at the pack station. The kraft outer shell is moisture-resistant and puncture-resistant, providing reliable protection through standard parcel handling.

The self-sealing design suits high-volume packing environments in e-commerce fulfillment, retail replenishment, and warehouse distribution. The self-contained padding removes the need for poly bags, bubble wrap inserts, or loose fill, reducing material handling steps when shipping documents, flat goods, and small soft items.

Closure is achieved through end flaps coated with natural rubber adhesive that bonds only to itself — no water activation or heat-sealing equipment required. Each case contains 100 mailers and ships via parcel carrier.
