The BSC PREFERRED MFL3RB is a white corrugated document mailer box sold in a pack of 50. Built from 200/ECT-32-B corrugated board, these mailers provide rigid protection for flat documents, files, certificates, and similar materials during shipping or storage. Protective side flaps and a front outside tuck closure lock contents securely without the need for tape, glue, or staples. The tool-free assembly makes these practical for high-volume packing environments where speed and consistency matter.
These mailers are suited for offices, fulfillment operations, and mailrooms that ship flat or folded documents on a regular basis. The white corrugated construction presents a clean appearance while delivering structural support against compression and edge damage in transit. Each unit assembles quickly, making them a reliable option for professionals packaging legal documents, architectural drawings, certificates, or standard letter-size correspondence.
Equivalent to part number S-9844. Designed as a standard corrugated document mailer suitable for flat and folded document shipping applications.
No tools are required for assembly. Fold along the scored lines, engage the side flaps, and secure the front tuck closure before inserting documents. Store flat in a dry location prior to use to maintain board integrity. Follow carrier packaging guidelines when preparing mailers for shipment.
