A public water utility in Colorado was having fluoride powder delivered to its silos via self-unloading, pressure-differential trucks and pneumatic conveying lines. After switching powder suppliers, the fluoride powder was delivered in bulk bags, so the utility had to figure out a new way to transport the powder to the silos. An engineer from Golden Eagle Technologies and bulk solids equipment supplier Vibra Screw came up with a portable solution.
FIBCs are being used throughout the powder and bulk solids industry to pack, transport, and store materials. This article discusses various principles to be aware of when dealing with bulk bags, including design, sizing, handling, and filling, to help ensure that they’re employed in the safest, most efficient, and most cost-effective way.
When customers requested product in bulk bags, a contract processor added a bulk bag filler.
Handling dry bulk solids in bulk bags can produce electrostatic discharges. In a potentially explosive environment, the result can be a damaging dust or flammable vapor explosion. This article describes the factors that create a potentially explosive environment in your plant, how to assess your explosion risks, and one type of antistatic bulk bag that dissipates electrostatic charges using conductive fabric and a grounding device.
A bulk bag, also called a flexible intermediate bulk container, can inexpensively and easily move and store from 500 to 8,000 pounds of bulk materials. This article discusses some bulk bag basics and then provides guidelines to help you safely fill, transport, and discharge bulk bags.
Du Pont satisfies its customers' demands by switching from multiwall kraft bags to high-barrier, laminated plastic bags with one-way degassing valves, which allow moisture, air, and other gases to escape from the bags without letting moisture or air back in.
The flexible intermediate bulk container is a cost-effective and popular method of shipping and storing dry bulk products. To protect your company and customers, every FIBC you use should meet or exceed the voluntary performance standards published by The Chemical Packaging Committee of The packaging Institute USA, in conjunction with the Flexible Intermediate Bulk Container Association USA and the Materials Transportation Bureau of the US Department of Transportation. The standards listed here are minimum criteria; you may desire additional testing of your bags based on the specific needs of your product or operation.
Despite the advantages bulk bags provide -- including large capacity [as much as 160 times that of smaller bags] and reusability -- filled bulk bags present a number of storing and handling problems. This article describes how loading filled bulk bags on portable storage racks can solve these problems. Sections provide basic information about portable storage racks, discuss how a portable storage rack can solve storing and handling problems, and explain how to select a portable storage rack.
Bag innovations are not only making bags stronger, more reliable, and more attractive, but easier to fill, seal, store, and ship and easier for your customers to handle and empty. This article introduces several improvements in paper and plastic bags that can enhance your dry bulk solids bagging operation and your customers' satisfaction.
Using a flexible intermediate bulk container [FIBC], also called a bulk bag, to ship and store dry bulk materials is cost-effective, making the container increasingly popular for material suppliers and users, as well as custom packagers and shippers. This article discusses two industry trends -- reusing and recycling FIBCs -- as well as some cautions and guidelines you should know about.
If your company ships its dry bulk products in 20- to 100-pound bags, you should periodically evaluate whether your bag still meets your customer demands. New options in bag materials and bagging technology can make your product more attractive to customers and help you sell more. This article examines recent trends in multiwall paper bags and plastic bags and the typical customer demands and technology changes that drive them. It also provides general guidelines for selecting an economical bag for your product.1

A company installs an airionization system in its FIBC-loading operation to remove static charges from the bags' surfaces and eliminate nuisance shocks to its operators.
When a bulk bag fails, it's more than just a cleanup problem. The couple of thousand pounds of spilled product left on the ground represents a big production loss -- especially if the bag contains a high-value product. Two of the biggest causes of bulk bag failures are forklift handling problems and ultraviolet degradation of the bag components as the result of outdoor storage. This article gives some practical advice for avoiding these problems and the headaches that come along with them.
When manually handling paper bags required heavy lifting in a dusty environment, a refractory manufacturer switched to a bulk bag batching system.
While more than 3 billion multiwall paper shipping bags are used every year in the United States, very few people know much about them, including people who use them regularly. This article introduces you to multiwall bag definitions, terminology, materials, and styles. With this information, you'll be able to speak the language of bags and work better with your bag supplier to determine the best way to ship your bagged product.
The tremendous growth in bulk bag use in the last three decades has spurred bag specialization.
