Bsc Preferred M431 Corrugated Mailers White 50 Pack

Product Description

The BSC PREFERRED M431 is a white corrugated mailer designed for shipping small, lightweight fragile items through postal and parcel networks. Manufactured from 200/ECT-32-B corrugated board, these mailers fold to create double walls of protection on the front and sides, adding crush resistance without adding significant weight. No tape, glue, or staples are required for closure, which speeds up packing workflow. At 2.88 pounds per pack, the lightweight construction helps keep postage costs down on individual shipments. Each pack contains 50 mailers, making it a practical quantity for warehouse, mailroom, and shipping department use.

These corrugated mailers suit residential, commercial, and industrial shipping operations where small, fragile items need reliable protection in transit. Typical applications include e-commerce fulfillment, parts distribution, and mailroom operations that handle items such as small electronics, samples, documents, and similar goods. The self-folding design supports high-volume packing environments where speed and consistency matter. This product is equivalent to part number S-15073.
