A flexible intermediate bulk container (FIBC) is defined as an intermediate bulk container, having a body made of flexible fabric, which

• Cannot be handled manually when filled
• Is intended for shipment of solid material in powder, flake, or granular form.
• Does not require further packaging
• Is designed to be lifted from the top by means of integral, permanently attached devices (lift loops or straps)

Flexible intermediate bulk containers (FIBCs), also known as "big bags," "bulk bags," and "bulk sacks," were first manufactured in the late 1950s or early 1960s.  There is some controversy as to where the first FIBCs were made; however, it is known that FIBCs were made in the United States, Europe, and Japan during the time period mentioned above.  The first FIBCs were constructed with heavy-duty PVC-coated nylon or polyester where the cut sheets are welded together to form the FIBC.  These FIBCs were made with integrated lift slings around the container, or attached to a specially made pallet, or a metal lifting device that the container sat on.  The handling devices allowed the container to be filled from the top and discharged from the bottom.
