Bsc Preferred MRX1XLK Kraft Corrugated Mailers 50 Pack

Product Description

The BSC PREFERRED MRX1XLK is a pack of 50 kraft corrugated mailers designed for shipping small, lightweight, and fragile items while keeping postage costs low. Each mailer is constructed from 200/ECT-32-B kraft corrugated board, a specification that indicates a burst strength of 200 pounds per square inch and an edge crush test rating of 32. The fold-over design creates double walls of protection on the front and sides, adding crush resistance without adding significant weight. No tape, glue, or staples are required for closure, making these mailers fast to pack and ready to ship straight off the shelf.

These mailers are suited for light-duty shipping and fulfillment operations across e-commerce, distribution centers, mail rooms, and supply houses. They are a practical choice for sending documents, small parts, electronics accessories, or other fragile flat items that require more protection than a standard envelope but do not need a full corrugated box. The self-sealing fold design speeds up packing workflows in environments where volume and efficiency matter.

Installation Notes

No tools are required to prepare these mailers for use. Fold along the pre-scored lines to form the double-wall structure before placing items inside. Ensure contents are positioned securely within the mailer before completing the fold closure. Store unused mailers flat in a dry environment to prevent moisture absorption that could compromise board integrity.
