The BSC PREFERRED RM9K is a stayflat chipboard mailer designed to protect photos, documents, and flat printed materials during shipping and mailing. Constructed from 0.028-inch kraft chipboard, the rigid panel eliminates the need for additional stiffeners inside the envelope. The lightweight construction helps keep postage costs low on standard letter and flat-rate mail runs. A peel-and-seal adhesive closure speeds up packing, while a pull tab tear strip on the receiving end allows for clean, easy opening without scissors or tools. Each case contains 200 mailers.
These mailers are suited for shipping and fulfillment operations that regularly send flat, rigid items such as photographs, certificates, contracts, artwork prints, and similar documents. They are commonly used in print shops, photography studios, offices, and light distribution environments where consistent flat-mail presentation and contents integrity matter. The case quantity of 200 supports moderate-to-high-volume mailing workflows without frequent reordering.
Designed as a direct equivalent to part number S-5464. Suitable as a general-purpose stayflat mailer for photos, documents, and flat printed materials in standard mailing and fulfillment applications.
No tools are required for use. Fold or insert contents flat before activating the peel-and-seal closure to ensure a secure bond. Store unused mailers flat in a dry environment to prevent warping of the chipboard panels. Handle the adhesive strip carefully to avoid premature activation before sealing.
