Bag Sealing Machines

A bag sealer is a machine used to close and secure the open end of a bag. The machine works by heating a sealing strip to a temperature that fuses the bag material together to create a permanent bond.

BW Flexible Systems bag sealer machines remain the industry standard of economy and reliability. Our industrial bag sealing machines feature small footprints, increased safety, and enhanced operation for a smoother, faster production process.

Our equipment is suited for a variety of markets. Machines are designed with hygiene in mind, thanks to a fully stainless-steel construction.
