Bsc Preferred M322 Corrugated Mailers White 200/ECT-32-B 50 Pack

Product Description

The BSC PREFERRED M322 is a white corrugated mailer designed for shipping small, lightweight, and fragile items without the need for tape, glue, or staples. Built from 200/ECT-32-B white corrugated board, each mailer folds to create double walls of protection on the front and sides, delivering crush resistance for contents in transit. The self-sealing fold construction keeps the assembly secure while minimizing prep time during packing operations. Each pack contains 50 mailers, making this a practical stock item for mailrooms, warehouses, and shipping departments that process moderate to high volumes of small parcels.

These mailers are suited for light-duty parcel shipping in commercial, industrial, and retail fulfillment environments. Their lightweight construction helps control dimensional and actual weight costs on outbound shipments. The self-locking design eliminates the need for additional sealing materials, which speeds up packing workflows. Shipping staff, warehouse associates, and packaging personnel are the typical end users. This product is equivalent to part number S-435.

Installation Notes

No tools or fasteners are required to assemble these mailers. Fold along the scored lines to form the double-wall enclosure before inserting contents. Ensure contents fit without forcing the fold, as overstuffing can compromise the crush-resistant structure. Store flat in a dry environment to maintain board integrity prior to use.
