This gravity filler is designed for the low-capacity packing of free-flowing granular and pelletized type products. This gross weigh bagger utilizes a simple gravity feeder to meter product into the bag, leveraging product flow characteristics and eliminating the need for a powered fill. Prior to filling, the bag is inflated to expand the bag volume. The bag is filled in a declined position to allow the product to flow into the bag, and ensure a complete fill.
