Bsc Preferred M1042K Kraft Corrugated Mailers Pack of 50

Product Description

The BSC PREFERRED M1042K is a pack of 50 kraft corrugated mailers designed for shipping small, lightweight, and fragile items while keeping postage costs low. Constructed from 200/ECT-32-B kraft corrugated board, 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 the pack-and-ship process fast and straightforward. The lightweight construction directly reduces dimensional and actual weight costs for high-volume shippers and fulfillment operations.

These mailers are suited for businesses and operations that regularly ship small parts, samples, documents, or fragile items through standard parcel and postal carriers. The self-locking fold design makes them practical for warehouse staff, shipping departments, and fulfillment centers where speed and consistency matter. Each pack contains 50 mailers, sold as a single pack unit.

Ensure contents fit within the mailer dimensions without forcing the closure, which can compromise the lock. Store flat in a dry environment to maintain board integrity before use.
