Bsc Preferred MRX4X Corrugated Mailers White Pack of 50

Product Description

The BSC PREFERRED MRX4X is a pack of 50 white corrugated mailers built for shipping small, lightweight fragile items without adding unnecessary bulk or postage cost. Each mailer is manufactured from 200/ECT-32-B white corrugated board, a material specification that delivers a reliable crush-resistance rating suited to standard parcel handling. The self-locking fold design creates double walls of protection on the front and all four sides, eliminating the need for tape, glue, or staples during packing. These mailers are a practical solution for shipping and receiving operations that demand consistent protection at high volume.

These corrugated mailers are suited for warehouse, mailroom, and fulfillment environments where small or fragile items need secure, lightweight packaging. The no-fastener closure speeds up pack-out workflows on shipping lines and reduces consumable costs. The white corrugated surface is also suitable for labeling directly with standard shipping labels. Sold as a pack of 50 units, this format is appropriate for both low-volume dispatch and bulk replenishment in storeroom inventory.
