The BSC PREFERRED MFL10104K is a corrugated document mailer box designed to protect flat documents, certificates, and important paperwork during shipping and storage. Constructed 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 shipping environments where speed and reliability matter. Each pack contains 50 mailers, making it a solid choice for mailrooms, fulfillment centers, and office supply rooms that process document shipments regularly.
This mailer is suited for residential and commercial applications where flat, rigid document protection is required. Typical use cases include legal offices, accounting firms, architectural firms, and any operation shipping certificates, contracts, blueprints, or similar flat media. The tuck-front closure allows fast, repeatable assembly on a packing bench without additional fasteners or equipment. The side flap design adds structural rigidity and reduces the risk of corner damage during transit.
Designed as a direct equivalent to part number S-16956. Suitable as a general-purpose corrugated document mailer for flat-media shipping applications.
No tools, tape, or adhesives are required to assemble this mailer. Fold along pre-scored lines, engage the side flaps, and close the front tuck to secure contents. Store flat in a dry environment prior to use to maintain corrugated integrity. Handle packed mailers carefully to avoid compression damage to the closure panel during stacking.
