#0 white self-seal padded mailers offer a 6 x 10 inch interior with built-in fiber cushioning that expands during transit to absorb shock — eliminating the need for additional void fill or loose cushioning materials inside the mailer.

These mailers suit e-commerce order fulfillment, retail distribution, subscription box operations, and media shipping wherever flat or lightly fragile items need reliable protection. The moisture-resistant, puncture-resistant outer shell guards contents against handling damage and environmental exposure throughout the shipping process.

The peel-and-seal end flap uses a natural rubber adhesive that bonds only to itself, producing a tamper-resistant closure without tape or heat equipment. Each case contains 25 mailers and ships via parcel carrier, making it a practical stocking unit for operations with moderate mailer volume.
