Bsc Preferred M777 Corrugated Mailers White 50 Pack

Product Description

The BSC PREFERRED M777 is a white corrugated mailer designed for shipping small, lightweight, and fragile items without added weight. Manufactured from 200/ECT-32-B white corrugated board, these mailers fold to create double walls of protection on the front and sides, delivering crush resistance where it counts. No tape, glue, or staples are required to seal the mailer, which reduces labor time and speeds up packing operations. Each pack contains 50 mailers. The lightweight construction helps keep postage costs low while maintaining structural integrity during transit. Shipping and fulfillment staff in distribution centers, mail rooms, and supply houses will find these ready to use straight out of the box.

The M777 corrugated mailers are suited for e-commerce fulfillment, internal parts distribution, and any application requiring a fast, secure wrap for small fragile goods. The self-locking fold design eliminates the need for additional sealing supplies, making them practical for high-volume packing operations. Sold as a pack of 50 units, they are well suited to both low-volume and bulk shipping environments where consistent, repeatable protection is needed.

Installation Notes

No tools are required to assemble or close these mailers. Fold along the pre-scored lines to form the double-wall structure before placing the item inside. Ensure the contents are properly centered and do not exceed the mailer dimensions to maintain structural integrity during shipment. Handle stacked packs on a flat, dry surface to avoid pre-crush damage to the corrugated board.
