The BSC PREFERRED MFL20204K is a kraft corrugated document mailer box sold in a pack of 25. Built from 200/ECT-32-B corrugated board, it provides rigid, reliable protection for flat documents, files, and important paperwork during shipping and storage. The design features protective side flaps and a front outside tuck closure that locks the box shut without tape, glue, or staples.

This mailer box is suited for shipping or archiving flat documents, legal files, blueprints, certificates, or other materials that require rigid protection in transit. The tuck-closure design eliminates the need for additional sealing supplies at the point of packing. It is a standard choice in office, warehouse, and distribution environments where document integrity during shipping is a priority. The pack quantity of 25 makes it well-suited for operations with recurring document mailing needs.
Equivalent to part number S-16966. Designed as a standard corrugated document mailer for flat-pack shipping applications across general commercial and office distribution use.
No tools required for assembly. Fold along pre-scored lines and tuck the front closure tab to secure. Ensure contents are fully seated before closing to prevent shifting in transit. Store flat-packed units in a dry environment to maintain corrugated board integrity prior to use.
