Bsc Preferred M1644K Kraft Corrugated Mailers Pack of 50

Product Description

The BSC PREFERRED M1644K is a pack of 50 kraft corrugated mailers designed for shipping small, lightweight, and fragile items through standard mail or parcel carriers. Each mailer is manufactured from 200/ECT-32-B kraft corrugated board, a widely recognized performance standard for crush resistance in transit. When folded, the mailer creates double walls of protection on the front and sides, reducing the risk of damage to contents without adding significant weight. No tape, glue, or staples are required to seal these mailers, which speeds up packing workflows and lowers consumable costs. The lightweight construction helps keep postage costs down on high-volume shipping runs.

These corrugated mailers are suited for warehouse, fulfillment, office, and distribution center environments where frequent small-parcel shipping is routine. They are a practical choice for e-commerce operations, parts distribution, and any application requiring a self-sealing, protective mailer for delicate or breakable goods. The pack-of-50 unit of measure supports both low-volume and moderate-volume shipping operations without requiring bulk pallet purchasing.
