The 7 1/4 x 12 inch TerraBoard™ Flat Mailer is a rigid kraft-finish mailer built from 100% recycled content, with 75% derived from post-consumer material. That sustainability profile sets it apart from conventional padded or poly mailers, offering a more responsible enclosure without sacrificing structural protection during transit.

The interior dimensions accommodate documents, media, soft goods, small accessories, and other flat or low-profile items that need protection from bending or crushing. It suits e-commerce fulfillment operations, retail distribution centers, subscription box programs, and any environment where professional presentation and mail integrity both matter. The kraft exterior accepts standard shipping labels and branding overlays cleanly.

Each case contains 250 mailers, supporting consistent per-unit cost control at volume. The mailer ships via parcel carrier, keeping replenishment simple for facilities ordering at case quantities.
