Bsc Preferred M1264K Kraft Corrugated Mailers 50-pack

Product Description

The BSC PREFERRED M1264K is a pack of 50 kraft corrugated mailers designed for shipping small, lightweight, and fragile items through standard postal and carrier services. Constructed 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, which speeds up packing operations. At 18.6 pounds per pack, the individual mailers remain lightweight enough to help keep postage costs low. Shipping and fulfillment staff, warehouse teams, and small business operators are the primary users.

These mailers are suited for residential and commercial shipping environments where small, breakable, or impact-sensitive items need basic structural protection during transit. Typical applications include e-commerce order fulfillment, parts distribution, and retail returns packaging. The self-folding design makes them practical for high-volume packing operations where speed and consistency matter. Each pack contains 50 mailers, sold as a single unit of measure (PK).

Installation Notes

No tools or fasteners are required for assembly. Follow the fold lines to form the double-wall structure before inserting the item.

Store flat in a dry environment to preserve the corrugated material's structural properties.
