Bag Filling Equipment - Semi-Free Flowing

Fill a variety of bag types and sizes with a semi-free flowing bagging machine from BW Flexible Systems. These machines are designed to bag free and semi-free flowing products at high speeds.

BW Flexible Systems is a worldwide provider of automatic bagging machines engineered to make your production line more efficient. We have over 50 years of experience in machine design, integration, and support.

How Do Semi-free Flowing Bagging Machines Work?

Each bag filling machine operates in its own way. The main function of the bagging machine is filling bags, which are fed into the machine, and transporting them to the filling mechanism. Then, the product bags are filled with a set amount of product.

Various BW Flexible Systems’ machines, such as the Thiele 3110 Bag Filling System and the 3109 Bag Filling System, are designed to be fully automatic.

Many of these free to semi-free flowing product baggers are engineered to minimize dust during production. This helps with keeping your machine and workspace clean.
