Bsc Preferred M743 Corrugated Mailers White 50 Pack

Product Description

The BSC PREFERRED M743 is a white corrugated mailer designed for shipping small, lightweight fragile items without sacrificing protection. Manufactured from 200/ECT-32-B white corrugated board, these mailers fold to create double walls of protection on the front and all sides. The self-locking design requires no tape, glue, or staples, streamlining the packing process for high-volume shipping environments. Sold in packs of 50, they are a practical choice for warehouses, fulfillment centers, and distribution operations looking to reduce postage costs while maintaining product integrity in transit.

These mailers are suited for lightweight, fragile items that require rigid protection during shipping. The corrugated construction provides crush resistance without adding significant weight to the package. They are commonly used in e-commerce fulfillment, retail backroom operations, and light industrial shipping applications. The pack-of-50 format supports efficient restocking and consistent throughput at packing stations.
