The BSC PREFERRED MFL18126K is a kraft corrugated mailer box designed to protect flat documents, files, and important paperwork during shipping and storage. Built from 200/ECT-32-B kraft corrugated material, it provides a rigid, crush-resistant enclosure suited for mailing or archiving applications. The design includes protective side flaps and a front outside tuck closure that locks the contents securely without requiring tape, glue, or staples. Assembly takes only seconds. This pack contains 25 individual mailer boxes and is typically stocked and deployed by shipping departments, print shops, office supply operations, and facilities managers handling document distribution.
These mailer boxes are suited for residential and commercial shipping environments where flat or bound documents require firm protection against bending and impact. The front tuck closure and side flap construction make them practical for high-volume mailing workflows where fast assembly and consistent closure are priorities. The 200/ECT-32-B corrugated rating indicates the board meets standard edge crush test requirements for light-duty parcel and mailer applications. Each unit ships flat and assembles on demand, making storage efficient in warehouse or mailroom settings.
Designed as a standard corrugated mailer box suitable for shipping and storing flat documents, files, and similar materials in general mailroom and shipping department applications.
No tools are required for assembly. Fold along the pre-scored lines and engage the front tuck closure to secure the box. Verify that contents fit within the interior dimensions before sealing. For outbound shipments, confirm that carrier labeling and postage requirements are met per applicable carrier guidelines.
