Bsc Preferred M1BK Corrugated Flat Mailer Pack of 50

Product Description

The BSC PREFERRED M1BK is a white corrugated flat mailer designed for safely shipping books, catalogs, framed pictures, and similarly sized flat or semi-flat items. Built with 200/ECT-32-B corrugated construction, it provides a sturdy, crush-resistant enclosure without requiring pre-formed carton assembly. The mailer is scored at multiple depths, allowing the packager to fold the sides at the desired depth before sealing with tape. Each pack contains 50 mailers. The white exterior finish presents a clean, professional appearance suitable for direct-to-customer shipments.

This mailer is well-suited for lightweight parcel and media mail applications in warehouse, fulfillment, and mailroom environments. The scored fold lines allow quick adaptation to varying product thicknesses, reducing the need for multiple box sizes on hand. Packaging and shipping operations handling books, catalogs, printed materials, or framed artwork will find this mailer a practical stock item. It is equivalent to part number S-341, which makes it a direct cross-reference replacement for facilities already sourcing that item.
