The BSC PREFERRED MFL18123 is a white corrugated document mailer box engineered for maximum protection of flat documents, certificates, and important paperwork during shipping and storage. Built from 200/ECT-32-B single-wall corrugated board, this mailer features protective side flaps and a front outside tuck closure that locks contents securely without tape, glue, or staples. The tool-free assembly design allows fast, repeatable setup on a packing bench. Each pack contains 25 mailers. This product is equivalent to part number S-2737. Licensed contractors, fulfillment staff, and shipping departments handling high-volume document dispatch will find the no-fastener design reduces labor per unit.
These mailers are suited for light industrial, office, and distribution center environments where flat or near-flat items such as legal documents, blueprints, photographs, and certificates require rigid transit protection. The corrugated construction resists crush forces that standard envelopes cannot handle. Sold in packs of 25, they are well-suited for moderate-to-high-volume document shipping operations where consistent packaging quality is required.
Equivalent to part number S-2737. Designed as a standard corrugated document mailer suitable for flat and near-flat document shipments in residential, commercial, and light industrial mailing applications.
No tools, tape, glue, or staples are required for assembly. Fold side flaps inward before inserting documents, then engage the front tuck closure to secure the load. Store flat mailer blanks in a dry location away from moisture to maintain board integrity. Handle finished mailers carefully to avoid compromising the tuck closure before dispatch.
