Bsc Preferred M642 Corrugated Mailers White 50 Pack

Product Description

The BSC PREFERRED M642 is a white corrugated mailer designed for shipping small, lightweight, and fragile items. 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 lightweight construction helps keep postage costs down without sacrificing structural integrity. No tape, glue, or staples are required to close them, making assembly fast in a packing or shipping environment. Each pack contains 50 mailers, sized for efficient storage and high-volume use.

These corrugated mailers are well suited for e-commerce fulfillment operations, mail rooms, distribution centers, and any facility that regularly ships small fragile goods. The self-closing design speeds up packing workflows and reduces the need for secondary fastening materials. The white exterior provides a clean presentation suitable for retail or direct-to-consumer shipments. Sold in a pack of 50, they are practical for both low-volume and high-volume shipping applications.
