The BSC PREFERRED MFL15112K is a kraft corrugated document mailer box designed to protect flat documents, certificates, contracts, and other critical 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 requiring tape, glue, or staples. The tool-free assembly makes it practical for high-volume shipping operations. Sold in a pack of 50 units, this mailer is suited for mailrooms, office supply rooms, and warehouse shipping stations where document integrity during transit is a priority.
This mailer box is appropriate for shipping flat or near-flat documents in both commercial and light industrial environments. The front tuck closure and side flap design provide all-around coverage, reducing the risk of edge damage or moisture intrusion during handling. Packaging and shipping departments, administrative teams, and fulfillment centers handling legal, architectural, or business documents are the primary users. Each unit assembles quickly, keeping packing lines moving without added consumables.
Designed as a standard corrugated document mailer suitable for shipping flat documents, certificates, blueprints, and similar materials requiring rigid envelope-style protection.
No tools are required for assembly. Fold along pre-scored lines, engage the side flaps, and close the front tuck to secure contents. Ensure documents are properly centered before closing to prevent shifting during transit. Store flat and unassembled in a dry environment to maintain board integrity prior to use.
