The BSC PREFERRED RM1 is a rigid chipboard stayflat mailer engineered to protect photos, documents, and flat materials during shipping and handling. Constructed from 0.036-inch kraft chipboard, these mailers provide firm, lightweight protection without requiring additional stiffeners. The tab lock closure secures contents without tape or adhesive strips. Sold in cases of 100, the RM1 is well suited for mailrooms, fulfillment operations, shipping departments, and any application where flat-item integrity must be maintained in transit.
These mailers are designed for shipping photos, prints, certificates, documents, and other flat materials that cannot be folded or bent. The lightweight chipboard construction helps keep postage costs down while still delivering reliable rigidity. The case quantity of 100 makes the RM1 a practical choice for high-volume shipping environments, including commercial print shops, administrative offices, and distribution centers.
Designed as an OEM-style equivalent to part number S-2219. Suitable for standard flat-item mailing and shipping applications where stayflat mailers are required.
No tools are required to prepare or use these mailers. Fold and engage the tab lock closure firmly to ensure contents are secured before handing off to a carrier. Store unused mailers flat in a dry environment to prevent warping or moisture damage to the chipboard.
