Bsc Preferred M444K Kraft Corrugated Mailers Pack of 50

Product Description

The BSC PREFERRED M444K is a pack of 50 kraft corrugated mailers designed for shipping small, lightweight fragile items while keeping postage costs low. Manufactured from 200/ECT-32-B kraft corrugated board, these mailers fold into a double-wall construction that provides crush resistance on the front and sides. No tape, glue, or staples are required to seal them, making the pack-and-ship process fast and clean. Shipping professionals, fulfillment teams, and warehouse staff will find these a practical staple for everyday light-duty parcel operations.

These mailers are suited for e-commerce fulfillment, trade supply distribution, and any application where protecting small, fragile goods during transit is a priority. The lightweight construction is intentional - keeping the mailer weight low reduces total shipment weight and helps control carrier costs across high-volume shipping operations. Sold as a pack of 50 units, they are appropriate for both low-volume and recurring restocking scenarios.

Installation Notes

No tools or fasteners are required to assemble these mailers. Fold along the pre-scored lines to form the double-wall enclosure before placing the item inside. Ensure the contents fit within the interior dimensions without forcing the closure, which can compromise the fold lock. Store unused mailers flat in a dry environment to prevent moisture absorption that may weaken the board.
