The BSC PREFERRED M1044 is a pack of 50 white corrugated mailers built for shipping small, lightweight fragile items through standard mail and parcel carriers. Manufactured from 200/ECT-32-B white corrugated board, these mailers fold into a self-contained enclosure that creates double walls of protection on the front and sides without requiring tape, glue, or staples. The lightweight construction helps keep shipping weight low, which can reduce postage costs on high-volume shipments. Each mailer is crush resistant and self-sealing by design, making them a practical choice for warehouses, fulfillment operations, and shipping departments that process frequent small-parcel outbound orders.
These corrugated mailers are suited for light-duty protective packaging applications including e-commerce fulfillment, retail returns processing, and direct mail shipments of small fragile goods such as electronics accessories, jewelry, cosmetics, and similar items. The self-locking fold design speeds up packing workflows by eliminating the need for additional fasteners or sealing materials. The pack contains 50 individual mailers and is sold as a single pack unit. This product is equivalent to part number S-434.
Designed as a general-purpose corrugated mailer for standard small-parcel and postal shipping applications where lightweight crush-resistant protection is required.
No tools are required to assemble these mailers. Follow the fold lines to form the enclosure and seat the locking tabs before inserting contents. Ensure contents do not exceed the structural capacity of the mailer walls to maintain crush resistance during transit. Store flat in a dry environment to preserve board integrity prior to use.
