Bsc Preferred MRX5XK Kraft Corrugated Mailers 50-pack

Product Description

The BSC PREFERRED MRX5XK is a pack of 50 kraft corrugated mailers built for shipping small, lightweight fragile items while keeping postage costs low. Manufactured from 200/ECT-32-B kraft corrugated material, these mailers fold into a self-locking design that creates double walls of protection along the front and sides. No tape, glue, or staples are required to seal them. The crush-resistant construction helps protect contents during transit without adding unnecessary bulk or weight. This pack is sold as a single unit of 50 mailers, making it a practical stock item for shipping departments, warehouses, and fulfillment operations.

These corrugated mailers are suited for light-duty shipping applications where a padded envelope falls short but a full corrugated box would add unnecessary weight and cost. Common uses include shipping documents, photos, small electronic components, craft items, and other fragile flat goods. The self-locking fold eliminates the need for additional sealing supplies at the packing station, which speeds up fulfillment workflows. Each mailer provides consistent, repeatable protection without relying on operator technique for sealing.

Installation Notes

No tools are required to assemble or seal these mailers. Fold along the pre-scored lines to form the double-wall structure and lock the closure tab to secure contents. Verify that item weight and dimensions are within carrier guidelines before dispatch. Store unused mailers flat in a dry environment to prevent moisture absorption that could affect corrugated strength.
