The TerraBoard™ Flat Mailer is a rigid kraft board mailer built from 100% recycled content, including 75% post-consumer material. The board construction resists flex and surface pressure in transit, keeping flat and semi-rigid contents protected without the bulk of padded alternatives.

These mailers suit e-commerce fulfillment, retail distribution, and direct-to-consumer operations shipping items such as documents, photos, art prints, thin apparel, and lightweight electronics accessories — any product that requires bend protection but not cushioning. The fully recyclable construction supports sustainability commitments at the packaging procurement level.

Mailers measure 12 1/2 x 15 inches and are sold in cases of 250. Cases ship via parcel carrier, making them practical for replenishment without lead-time complications typical of larger format packaging.
