ABSTRACT:
A method for filling a flexible container with a flowable material is provided, including the steps of filling the flexible container, suspending the flexible container, transferring the weight of the flexible container from being suspended to being supported by a support surface, and applying a hoop force to the flexible container to substantially maintain a configuration of the flexible container. The flexible container can be a bag-type container for containing flowable material such as chemicals, food products, agricultural products, and plastic pellets. As the container is lowered from the suspended position to a bottom-supported position, the hoop force is applied around the perimeter as the perimeter changes during transfer of the flexible container from being suspend to being bottom-supported. The hoop force can be applied by stretch wrap. Alternatively, the first flexible container can be lowered into a second flexible container. The second flexible container can be formed from a heat shrinkable material and the second flexible container can be shrunk at the perimeter as the perimeter changes. Alternatively, the second flexible container can be a stretchable bag. A stretched portion of the stretchable bag can be released substantially at the perimeter to generate the hoop force.
