The BSC PREFERRED MFL15114 is a white corrugated document mailer box designed to protect flat documents, certificates, and important paperwork during shipping and storage. Constructed from 200/ECT-32-B corrugated material, it features protective side flaps and a front outside tuck closure that holds the box shut without tape, glue, or staples. The design allows for fast assembly, making it practical for high-volume shipping operations. Each purchase includes 50 mailer boxes per pack. This product is an equivalent replacement for part number S-11230.
This mailer is suited for office supply rooms, shipping departments, print shops, and any operation that regularly mails flat documents, legal-size papers, blueprints, or certificates. The tuck-closure and side-flap design keeps contents flat and protected against bending and corner damage in transit. The white corrugated exterior also accepts labels cleanly, supporting standard shipping and tracking workflows without additional prep.
Equivalent to part number S-11230. Designed as a direct replacement for standard corrugated document mailer boxes of the same construction and closure style.
No tools are required for assembly. Fold along pre-scored lines, tuck the front closure into place, and load documents before sealing. For shipments requiring additional tamper evidence, apply a label over the tuck closure after loading. Store flat in a dry location prior to use to maintain corrugated integrity.
