Bsc Preferred MLR3 Corrugated Mailers White 50 Pack

Product Description

The BSC PREFERRED MLR3 is a self-sealing corrugated mailer designed to protect small, lightweight fragile items during shipping. Manufactured from 200/ECT-32-B white corrugated material, these mailers fold to create double walls of protection on the front and sides. No tape, glue, or staples are required for closure, reducing prep time at the packing station. Each pack contains 50 mailers. The lightweight construction helps keep shipment weight low, which can reduce carrier costs on high-volume outgoing orders.

These mailers are suited for warehouse, distribution, and light industrial shipping environments where fragile small parts, components, or merchandise need secure, damage-resistant packaging. The self-locking fold design makes them practical for fulfillment operations that require consistent, repeatable packing without additional sealing materials. Each pack of 50 is sold as a single unit of measure, making them straightforward to stock and reorder.
