The BSC PREFERRED M1033 is a corrugated mailer designed for shipping small, lightweight, and fragile items without tape, glue, or staples. Manufactured from 200/ECT-32-B white corrugated board, each mailer folds to create double walls of protection on the front and sides. The lightweight construction helps reduce postage costs while maintaining crush resistance during transit. Sold in packs of 50, these mailers are a practical choice for shipping departments, fulfillment operations, and warehouse professionals looking for a reliable, self-sealing protective mailer.
The M1033 mailer is suited for residential and commercial shipping applications where small, fragile items require added protection. The self-folding design eliminates the need for additional packing supplies, making it efficient for high-volume mailing and fulfillment workflows. Packaging and shipping professionals handling e-commerce returns, parts distribution, or light industrial shipments will find these mailers practical for daily use.
Designed as an OEM-style equivalent to part number S-845. Suitable for general-purpose corrugated mailer applications for small, lightweight fragile items.
No tools are required for assembly. Fold the mailer along the scored lines to form the double-wall structure before inserting the item. Ensure the item fits within the interior dimensions without forcing the closure. Store unused mailers flat in a dry environment to maintain board integrity.
