The BSC PREFERRED M833 is a white corrugated mailer designed for shipping small, lightweight, and fragile items through standard mail and parcel carriers. Constructed from 200/ECT-32-B white corrugated board, the M833 folds to create double walls of protection along the front and all four sides, providing crush resistance without adding excessive weight. No tape, glue, or staples are required for closure, making it a fast, tool-free option for packing operations. Each pack contains 50 mailers, suited for warehouse staff, shipping departments, and fulfillment operations handling light-duty protective packaging needs.
The M833 is well-suited for e-commerce fulfillment centers, print shops, and office mail rooms shipping items such as small electronics, photos, documents, jewelry, or other fragile goods. The self-locking fold design speeds up the packing process, making it practical for moderate-to-high-volume outbound shipping workflows. The lightweight construction helps keep shipment weight low, which is relevant for carriers that charge by dimensional or actual weight.
Designed as a standard corrugated mailer suitable for small, lightweight fragile items shipped via common parcel and mail carriers. Equivalent to part number S-975.
No tools or fasteners are required to assemble the M833 mailer. Fold along the pre-scored lines to form the double-wall enclosure before placing the item inside. Ensure the contents fit securely within the folded mailer without forcing the closure, which could compromise the structural integrity of the board. Store flat in a dry environment to preserve board strength prior to use.
