Valve sacks are designed for high speed filling on spout packers. The bag has a valve on the top which seals itself with the weight of the product when the sack is full. Alternatively, the valve can be sealed, for example using an ultrasonic sealer, to give a more secure, tamper evident or food grade closure.
Valve sacks are best suited to the packing of granular or powdered products such as cement, adhesives and seeds.
