Valve Bags

Valve bags, one of the most popular packaging solutions for powdered products such as flour, activated carbon, plastic granules, and cement. Their defining feature is a small opening or “valve” located at the corner of the bag, which facilitates efficient material filling. Internally, the valve incorporates a self-closing flap that acts as a check valve after filling, ensuring automatic sealing under the pressure of the bagged contents. This innovative design eliminates the need for manual closure, enhancing operational efficiency and minimizing product leakage.

VidePak has engineered certified valve bags for chemicals, construction, and food industries, producing over 100 millions annually under ISO 9001 standards.
