Bsc Preferred RM3K Stayflat Chipboard Mailer 100/case

Product Description

The BSC PREFERRED RM3K is a rigid stayflat mailer designed to protect photos, documents, and other flat items during transit. Manufactured from 0.028-inch kraft chipboard, the mailer provides firm support without requiring additional stiffeners inside the envelope. The lightweight construction helps keep postage costs low while still delivering reliable protection. A peel-and-seal closure secures contents quickly, and a pull-tab tear strip allows recipients to open the mailer cleanly without damaging what is inside. This SKU is sold in a case quantity of 100 units.

The RM3K is suited for shipping flat materials such as photographs, certificates, contracts, and artwork through standard mail and parcel carriers. The stayflat chipboard construction prevents bending and creasing that commonly damages unprotected flat-item shipments. These mailers are commonly used in fulfillment operations, print shops, photography studios, and general business shipping environments where document integrity during transit is a priority.
