The BSC PREFERRED M741 is a white corrugated mailer designed for shipping small, lightweight, and fragile items without requiring tape, glue, or staples. Constructed from 200/ECT-32-B white corrugated board, these mailers fold to create double walls of protection on the front and sides, providing crush resistance during transit. The lightweight construction helps minimize postage costs while still offering reliable structural integrity. Each pack contains 50 mailers. These are a recognized equivalent to part number S-16524. Warehouse staff, shipping departments, and fulfillment operations typically stock these for routine outbound parcel needs.
The M741 mailers are suited for light-duty shipping applications in both commercial and light industrial environments. The self-folding design eliminates the need for additional fasteners or sealing materials, speeding up packing workflows. Their compact profile makes them practical for high-volume shipping operations where efficiency and cost control matter. The double-wall fold construction provides added protection for fragile goods such as glassware, small electronics, or media items that require more than a standard envelope but do not warrant a full corrugated box.
Designed as a direct equivalent to part number S-16524. Suitable for general light-duty parcel and mailer applications in shipping and fulfillment operations.
No tools or additional fasteners are required for assembly. Fold along the pre-scored lines to form the double-wall structure before inserting contents. Ensure the item is seated securely before closing the mailer to prevent movement during transit. Store flat in a dry environment to maintain board integrity prior to use.
