The BSC PREFERRED MFL1294K is a corrugated document mailer box sold in packs of 50. Built from 200/ECT-32-B kraft corrugated board, it provides rigid protection for flat documents, certificates, contracts, and other critical paperwork during shipping or storage. Protective side flaps and a front outside tuck closure secure contents without requiring tape, glue, or staples. The self-assembly design allows the box to be set up in seconds, making it practical for high-volume mailing operations. Trade supply managers, print shops, legal offices, and shipping departments rely on this format for consistent, damage-free document delivery.
This mailer is suited for business-to-business and business-to-consumer document shipments where flat, rigid protection is required. The tuck-close front panel keeps contents secure through standard parcel handling. The 200/ECT-32-B board rating indicates the corrugated material meets edge crush test requirements for lightweight parcel shipping. Each pack contains 50 mailers, supporting moderate to high mailing volumes without frequent reordering.
Designed as a standard corrugated document mailer suitable for flat-document shipments requiring rigid protection. This product is equivalent to part number S-16952.
No tools are required for assembly. Fold along score lines and tuck the front closure panel to close. Ensure documents are fully seated within the mailer before closing to prevent shifting during transit. Store flat in a dry environment prior to use to maintain board integrity.
