Valve sacks or pasted valve bags, are closed bags designed for high-speed filling through valves, mostly used for powdered and particulate substances, such as cement, pigment, animal food and particulate food. Valves can be easily closed after filling, no seaming needed. That’s why valve sacks are used extensively to carry building materials, chemicals, food and other powdered, particulate products.
