The BSC PREFERRED MFL17114K is a kraft corrugated mailer box engineered for secure document and flat-item shipping. Built from 200/ECT-32-B corrugated board, it delivers reliable edge crush resistance suitable for standard parcel handling. Protective side flaps and a front outside tuck closure keep contents sealed without requiring tape, glue, or staples. The self-assembly design lets warehouse staff or shipping teams set up each box in seconds, reducing pack-out time on high-volume fulfillment runs. Sold 50 units per pack, this SKU suits operations that move documents, certificates, prints, or similarly flat, rigid items in volume.
This mailer box is suited for light commercial and business-to-business shipping environments where document integrity is critical. Typical applications include fulfillment centers, print shops, legal and financial offices, and any operation shipping flat materials that must arrive undamaged. The kraft corrugated construction handles standard conveyor and parcel carrier conditions. Because no additional sealing materials are needed, it integrates cleanly into high-throughput packing stations.
Designed as a standard corrugated mailer suitable for flat documents, prints, certificates, and similarly dimensioned rigid or semi-rigid items shipped via standard parcel carriers.
No tools required for assembly. Fold along pre-scored lines and engage the tuck closure before inserting contents. Store flat in a dry location to maintain board integrity prior to use. Avoid stacking heavy items on assembled empty boxes to prevent premature crushing.
