Bsc Preferred M664K Kraft Corrugated Mailers Pack of 50

Product Description

The BSC PREFERRED M664K is a kraft corrugated mailer designed for shipping small, lightweight, and fragile items while keeping postage costs low. Manufactured 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 additional packaging materials. No tape, glue, or staples are needed to secure the closure. Each pack contains 50 mailers, making them a practical stock item for mail rooms, fulfillment operations, and shipping departments that handle frequent small-parcel dispatch.

These mailers are suited for light-duty shipping applications across a wide range of industries. The self-sealing, fold-to-close design speeds up packing operations and reduces the need for additional sealing supplies. They are appropriate for residential and commercial shipping scenarios where dimensional weight and postage savings are priorities, particularly for documents, small parts, electronics accessories, and similarly sized fragile goods.
