These 14 1/4 x 20 inch White #7 Self-Seal Padded Mailers combine an expanding fiber interior with a moisture- and puncture-resistant outer shell, delivering built-in cushioning without supplemental void fill or bubble wrap. The peel-and-seal closure uses a natural rubber adhesive that bonds to itself, forming a tamper-resistant seal without additional tape.

The #7 format suits e-commerce fulfillment, retail distribution, catalog operations, and direct mail programs shipping flat, flexible, or semi-rigid goods — apparel, documents, photographs, soft goods, and lightweight media are common applications. The self-contained construction streamlines packing by eliminating loose cushioning materials on the line.

Each mailer's fiber padding expands during transit to absorb impact, protecting contents through last-mile handling. Cases contain 50 mailers and ship via parcel carrier.
