These 12 1/2 x 19 inch bubble lined poly mailers feature a white polyethylene exterior bonded to an interior bubble cushioning layer, creating a self-contained protective mailer. The peel-and-seal adhesive strip forms a tamper-resistant closure without tape or added tools.

The bubble lining absorbs impact and limits content movement during transit, making these mailers well suited for e-commerce order fulfillment, subscription box operations, retail distribution, and multi-channel shipping environments handling lightweight or flat goods — apparel, accessories, printed materials, and similar products.

The polyethylene shell resists moisture and tearing through standard parcel handling conditions. Each case contains 50 mailers, a consistent pack quantity that supports inventory planning across pack stations and fulfillment centers. Order in case multiples to maintain steady stock at high-volume ship points.
