The BSC PREFERRED M1073K is a pack of 50 kraft corrugated mailers designed for shipping small, lightweight, and fragile items through the mail or parcel networks. Built 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 the bulk of a full box. No tape, glue, or staples are required for closure, which speeds up packing operations. The lightweight construction helps keep postage costs low, making these a practical choice for high-volume shipping applications.
These mailers are suited for e-commerce fulfillment centers, mailrooms, warehouses, and shipping departments that regularly send small or delicate items. The self-locking fold design eliminates the need for additional sealing supplies, reducing material costs and prep time per shipment. Each pack contains 50 mailers, and the package dimensions of approximately 24 inches by 25 inches by 5.75 inches make storage straightforward on standard shelving.
Designed as a general-purpose corrugated mailer suitable for shipping small, lightweight, and fragile items via standard parcel and mail carriers. Equivalent to part number S-18962.
No tools or adhesives are required to assemble these mailers. Fold along the pre-scored lines and tuck the closure tabs to secure the contents. Ensure the item fits within the interior dimensions before sealing to avoid overstressing the corrugated walls. Store flat in a dry location to preserve board integrity prior to use.
