Making the choice: Filling bulk bags by weight or by volume
Before buying a bulk bag filler, the biggest decision you need to make is whether to fill your bulk bags by weight or by volume. This article explains what factors go into choosing a filling method for your application and describes the components, operation, and options for fillers of each type.
Bulk bags, which typically hold between 1,000 and 3,000 pounds of powders or other dry solids, have many uses in dry bulk materials industries, including food, pharmaceuticals, chemicals, plastics, and construction. You don't need to be a dry solids processor to notice the bags everywhere: outside factories, on trucks and trains, at construction sites, and even at home improvement stores. Many bulk bags are used to ship finished products from manufacturing plants to customers, while others are used within plants to store and move raw and intermediate materials.
