The BSC PREFERRED MFL15114K is a kraft corrugated document mailer box designed to protect flat documents, files, and important paperwork during shipping and storage. Built from 200/ECT-32-B kraft corrugated material, this mailer features protective side flaps and a front outside tuck closure that locks contents securely without tape, glue, or staples. The tool-free assembly makes it practical for high-volume mailrooms, warehouses, and shipping departments. Sold in packs of 50, this SKU is well-suited for operations that require consistent, reliable document protection at scale.
This mailer is intended for shipping and storing flat documents, blueprints, certificates, legal files, and similar materials requiring rigid protection. The corrugated construction resists crushing and bending during transit. The front tuck closure design allows fast, repeatable assembly, making it a practical choice for shipping clerks and fulfillment staff processing multiple outgoing packages per shift. Each pack contains 50 units, reducing reorder frequency in active shipping environments.
Designed as a direct equivalent to part number S-16919. Suitable for use in standard document mailing and shipping workflows requiring corrugated flat mailers with tuck-style closures.
No tools required for assembly. Fold along pre-scored lines, engage side flaps, and tuck the front closure tab to close. Store flat in a dry environment prior to use to maintain board integrity. Handle stacked cartons with care to avoid compression damage to the corrugated flute structure before packing.
