Bsc Preferred M4BKK Corrugated Kraft Mailer 50 Pack

Product Description

The BSC PREFERRED M4BKK is a one-piece corrugated kraft mailer designed for economical, reliable product shipping. Built to 200/ECT-32-B kraft corrugated construction, it delivers a durable, lightweight enclosure that helps keep mailing costs down. The mailer features scores at multiple depths, allowing the installer or packer to fold the sides at the exact depth needed to snugly fit the product inside. Assembly requires no special tools: place the product in the center, fold the scored sides to the desired depth, and secure with tape. Sold 50 units per pack, the M4BKK suits warehouse, shipping room, and fulfillment center applications where consistent, adjustable packaging is required.

The M4BKK is suited for light-to-medium-weight items shipped through standard parcel carriers. Its adjustable-depth scoring makes it a practical choice for operations that handle a range of product sizes without stocking multiple box dimensions. The 200/ECT-32-B rating confirms adequate edge crush resistance for standard stacking and transit conditions. Each pack contains 50 mailers, making it appropriate for moderate-volume shipping operations as well as lower-volume applications where cost control matters.

Installation Notes

No tools are required for assembly. Place the product in the center of the mailer, fold the scored side panels inward to the desired depth, and apply tape to secure all seams. Ensure the chosen fold depth fully supports and immobilizes the contents before sealing. Store unused mailers flat in a dry environment to preserve board integrity.
