Bsc Preferred M553K Kraft Corrugated Mailers Pack of 50

Product Description

The BSC PREFERRED M553K is a pack of 50 kraft corrugated mailers designed for shipping small, lightweight, and fragile items while keeping postage costs low. Each mailer is manufactured from 200/ECT-32-B kraft corrugated board and folds to create double walls of protection on the front and sides. No tape, glue, or staples are required to close the mailer, which speeds up packing workflows. These mailers are well suited for warehouse operations, fulfillment centers, and any trade environment where frequent small-parcel shipments are part of daily operations.

These corrugated mailers are used across a wide range of packing and shipping applications where crush resistance and low weight are priorities. The self-closing fold design makes them practical for high-volume packing lines or counter shipping stations. Typical use cases include shipping small hardware components, replacement parts, sensors, controls, and other lightweight items that require protection from compression during transit but do not need a full rigid carton.
