Bsc Preferred M731 Corrugated Mailers White 50 Pack

Product Description

The BSC PREFERRED M731 is a white corrugated mailer designed for shipping small, lightweight, and fragile items without tape, glue, or staples. Constructed from 200/ECT-32-B white corrugated board, these mailers fold to create double walls of protection on the front and sides, delivering crush resistance where it matters most. The lightweight construction helps keep postage costs low while maintaining structural integrity during transit. Warehouse staff, shipping departments, and fulfillment professionals use these mailers for everyday outbound parcel operations.

These corrugated mailers are suited for residential and commercial shipping applications where a self-sealing, no-fastener solution is required. Typical use cases include e-commerce order fulfillment, parts distribution, and light industrial shipping of small or fragile components. Each pack contains 50 mailers, making them practical for moderate-volume shipping operations that need a reliable, ready-to-use option without additional sealing materials.
