Bsc Preferred M531 Corrugated Mailers White 50 Pack

Product Description

The BSC PREFERRED M531 is a white corrugated mailer designed for shipping small, lightweight, and fragile items without tape, glue, or staples. Built 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 self-locking construction keeps contents secure without additional fasteners. Each pack contains 50 mailers. At approximately 3.28 pounds per pack, the per-unit weight stays low enough to help control postage costs on outbound shipments.

These mailers are suited for light-duty protective shipping applications in distribution, fulfillment, and warehouse environments. The corrugated construction absorbs impact and resists compression forces common in parcel handling. The white exterior provides a clean surface appropriate for labeled or branded outbound packages. They are a practical choice for operations shipping small parts, retail goods, or other fragile items that require more protection than a padded envelope but do not need a full corrugated box.
