The BSC PREFERRED MFL12113K is a corrugated document mailer box designed to protect flat documents, reports, contracts, and similar materials during shipping and storage. Built from 200/ECT-32-B kraft corrugated stock, this mailer features protective side flaps and a front outside tuck closure that locks contents securely without tape, glue, or staples. The self-assembly design means the box is ready to use in seconds, reducing pack-out time on the floor. Each pack contains 50 units. This SKU is equivalent to part number S-16929.
This mailer is suited for shipping and storing documents that require flat, rigid protection - including legal files, architectural drawings, presentation folders, certificates, and similar materials. The corrugated construction resists crushing and bending in transit. The front outside tuck closure provides a clean, secure seal that is also easy to open on the receiving end. Facilities, shipping departments, and office supply rooms commonly stock this style of mailer for recurring document dispatch needs.
Designed as a standard corrugated document mailer suitable for flat document protection and shipping applications across office, facilities, and distribution environments.
No tools are required to assemble this mailer. Fold along the pre-scored lines and tuck the front closure tab to secure contents. Ensure documents are fully seated within the side flaps before closing to maximize edge protection during transit. Store flat in a dry location to maintain corrugated integrity prior to use.
