Bsc Preferred M641 Corrugated Mailers White 50 Pack

Product Description

The BSC PREFERRED M641 is a pack of 50 white corrugated mailers designed for shipping small, lightweight fragile items without tape, glue, or staples. Manufactured from 200/ECT-32-B white corrugated board, these mailers fold to create double walls of protection on the front and sides. The self-closing design speeds up packing operations and reduces consumable costs. Their lightweight construction keeps shipped package weight low, which matters when postage is calculated by weight. Warehouse staff, fulfillment operations, and shipping departments are the typical users of this product.

These mailers are suited for e-commerce, retail, and industrial shipping applications where small, fragile items need crush-resistant protection. The self-sealing fold eliminates the need for a tape dispenser or additional fasteners at the packing station, making them practical for high-volume light-duty shipping lines. Each pack contains 50 individual mailers, sold as one pack (PK) per unit of measure.
