The BSC PREFERRED M1066 is a white corrugated mailer designed for shipping small, lightweight fragile items without the need for tape, glue, or staples. Manufactured from 200/ECT-32-B corrugated board, these mailers fold into a self-contained enclosure that creates double walls of protection on the front and sides. The corrugated construction provides crush resistance while keeping overall weight low, helping reduce postage costs on outbound shipments. Each pack contains 50 mailers, making it practical for high-frequency shipping operations or stockroom supply.
These mailers are suited for distribution centers, fulfillment operations, mail rooms, and any facility that regularly ships small fragile goods. The self-locking fold design eliminates the need for additional sealing materials, streamlining the packing process. The white corrugated exterior also provides a clean surface for labeling. Sold by the pack of 50, the M1066 is a practical choice for businesses looking to standardize their protective mailer supply.
Designed as a general-purpose corrugated mailer for shipping small, lightweight fragile items across standard parcel and mail carrier services. This product is equivalent to part number S-9855.
No tools are required to assemble these mailers. Fold along the pre-scored lines to form the enclosure before placing the item inside. Ensure the contents fit within the interior dimensions without forcing the closure, which can compromise the double-wall protection. No additional sealing materials are needed, but label placement should avoid fold seams for best adhesion.
