These 9 x 12 inch clear poly mailing bags feature a self-sealing lip-and-tape closure and carry postal approval, meaning they meet USPS dimensional and material standards for direct insertion into the mail stream without overwrapping or additional sealing equipment.

The 2 mil polyethylene construction resists tearing through standard mail and courier handling, while full content visibility supports address verification and barcode scanning without opening the package. The absence of a tear strip delivers a clean, tamper-evident presentation at the point of delivery.

Sized to accommodate standard catalogs, brochures, photographs, and flat merchandise, these bags are well suited to e-commerce fulfillment, direct mail houses, and print distribution operations. Each case contains 1,000 mailers.
