Bsc Preferred MLR4 Corrugated Mailers White Pack of 50

Product Description

The BSC PREFERRED MLR4 is a white corrugated mailer designed for shipping small, lightweight fragile items without the need for tape, glue, or staples. Manufactured from 200/ECT-32-B white corrugated board, these mailers fold to create double walls of protection on the front and sides, providing crush-resistant performance during transit. The lightweight construction helps keep postage costs down while still delivering structural integrity. Each pack contains 50 mailers. Warehouse staff, shipping departments, and fulfillment operations are the primary users of this product.

The MLR4 mailer is well-suited for e-commerce fulfillment, retail distribution, and light industrial shipping environments where small, fragile items require reliable protection without added packing materials. The self-folding design speeds up the packing process, making it practical for high-volume shipping operations. Its white exterior also provides a clean presentation suitable for direct-to-consumer shipments.
