Bsc Preferred M642K Kraft Corrugated Mailers 50-pack

Product Description

The BSC PREFERRED M642K is a pack of 50 kraft corrugated mailers designed for shipping small, lightweight, and fragile items through standard mail or parcel services. Built from 200/ECT-32-B kraft corrugated material, these mailers fold to create double walls of protection on the front and sides, providing crush resistance without added bulk. No tape, glue, or staples are required to seal them, making them efficient for high-volume mailing operations. Their lightweight construction helps keep postage costs down, which matters for businesses processing large quantities of outbound shipments.

These mailers are suited for light-duty packaging applications in warehouse, fulfillment, office, and distribution environments. They work well for items such as documents, small electronics, jewelry, and other fragile goods that require some structural protection during transit. Each pack contains 50 individual mailers, and the self-contained folding design speeds up the packing process without the need for additional sealing supplies.

Installation Notes

Ensure the contents are seated securely before closing to prevent movement during transit. Handle corrugated mailers away from moisture, as exposure can reduce structural integrity.
