Valve Bags
Wellspring offers certified valve bags engineered for the chemical, construction, and food industries, producing millions annually under ISO 9001 standards.
Valve Bags
Valve bags are one of the most efficient and popular packaging solutions for powdered and granular products such as flour, cement, activated carbon, and plastic granules. Their key feature is a small corner “valve” that allows for quick and efficient filling. Inside, the valve includes a self-closing flap that automatically seals under the pressure of the bagged contents, eliminating the need for manual closure, reducing product loss, and improving operational efficiency.
