The BSC PREFERRED M942 is a self-sealing corrugated mailer designed to protect small, lightweight fragile items during shipping. Manufactured from 200/ECT-32-B white corrugated board, each mailer folds to create double walls of protection on the front and sides. No tape, glue, or staples are required for closure, which speeds up packing and reduces consumable costs. Sold in packs of 50, these mailers are a practical choice for operations shipping fragile goods in volume. The lightweight construction helps keep postage costs low without sacrificing crush resistance.
The M942 mailer is suited for warehouses, fulfillment centers, shipping departments, and any operation that regularly ships small fragile items such as electronics accessories, cosmetics, medical supplies, or other lightweight products requiring protection in transit. The self-closing design eliminates the need for a tape gun at the packing station, making it efficient for moderate to high-volume outbound shipping. Each pack contains 50 mailers, making it straightforward to manage inventory and reorder quantities.
Designed as a standard corrugated mailer replacement compatible with general small-parcel shipping applications. This product is equivalent to part number S-13366.
No tools or fasteners are required to assemble or seal the M942 mailer. Fold along the pre-scored lines and close the self-sealing flap before applying shipping labels. Store flat in a dry environment to maintain board integrity and prevent premature adhesive activation.
