<p>A flexible intermediate bulk container is formed from a fabric material and comprises four side walls connected together along the side edges. Two opposed side walls are folded inwardly along their longitudinal axes when the bag is collapsed and lie between two opposed unfolded side walls. The lower ends of the side walls are joined so that when the container is filled the lower ends of the side walls form a rectangular or square base for the container. A method is described for forming such containers.</p> |
