These #4 kraft self-seal bubble mailers combine a recycled golden kraft paper exterior with a 3/16" high-slip bubble lining, delivering lightweight cushioning without meaningfully increasing shipment weight. The peel-and-strip closure creates a tamper-evident bond with no additional tape or sealing equipment required.

The high-slip interior surface speeds loading and reduces snagging during insertion, making these mailers well-suited for e-commerce fulfillment, retail distribution, subscription box operations, and direct-to-consumer apparel and accessory shipping. They perform reliably for documents, soft goods, and other flat or lightly padded items.

Each mailer measures 9 1/2 x 14 1/2 inches and is designed for flat or low-profile products. Cases are packed in quantities of 25, keeping inventory increments manageable for small operations and multi-SKU facilities alike.
