Bsc Preferred MLRBL Corrugated Mailers White 50 Pack

Product Description

The BSC PREFERRED MLRBL is a pack of 50 white corrugated mailers built for shipping small, lightweight fragile items without adding unnecessary weight. Manufactured from 200/ECT-32-B white corrugated material, these mailers fold to create double walls of protection on the front and sides, providing crush resistance during transit. No tape, glue, or staples are required to close and secure each mailer. The design keeps postage costs low while maintaining structural integrity, making these a practical choice for fulfillment operations, shipping departments, and warehouse staff handling regular small-parcel outbound freight.

These corrugated mailers are suited for residential and commercial shipping applications where protecting lightweight fragile goods is the priority. Typical use cases include e-commerce order fulfillment, retail back-office shipping, and distribution center packing lines. Each pack contains 50 individual mailers, supporting moderate to high-volume shipping workflows. The self-folding, no-fastener design speeds up packing time on busy lines and reduces the need for additional sealing supplies.
