Intermediate bulk containers

Semibulk Containers. Use of semibulk containers falls between bulk handling, eg, accompHshed by tank cars and hopper cars, and individual package handling, which is often performed manually. Semibulk containers are also known as intermediate bulk containers (IBCs), the provisions and requirements for the constmction and testing of which can be found in the U.N. recommendations (4).

Many users of large amounts of water treatment chemicals have product supplied in either semi-bulk or bulk containers (tanker trucks). Semi-bulk usually means the supply of intermediate bulk containers (IBCs) or tote bins. These are reusable, stackable containers, holding 120 to 330 gal. (450 to 1250 1). One ton semi-bulks are very common. They are available in a variety of construction materials and configurations. The customer may hold two IBCs on-site for every product employed, with one IBC being exchanged as soon as it becomes empty. Alternatively, the IBC may be used to supply small day tanks. 

IBCs (intermediate bulk containers) must be clean and dry and made from material that can resist the temperatures when filling the container. The discharge temperature may have to be lowered to cope with the initial temperature of the prepolymer.
