ITN valve bag fillers are equipped with a belt bag filling system. A net weigh scale separate from the packer delivers preweighed product to the belt, and the belt into the bag. This bag filling system design encloses the belt in a purpose designed product flow channel, and is specifically suited for granular, free flowing products whose grain size must not be altered during packaging; products such as rice, plastic pellets, sugar, and fertilizers.

Each ITN is capable of a maximum production speed of between 360-400 bags/hour depending on the type of product and bag. If higher production rates are required, a system of up to 4 machines may be placed inline for production speeds of between 1200-1400 bags/hour.
