Patent ID: 7536840

Claim:
A method for packaging a plurality of particles comprising the steps of: filling a first radially flexible bulk container having a first large diameter with a plurality of particles to a first fill level; applying a stretch wrap to the first radially flexible bulk container to reduce the first large diameter of the first radially flexible bulk container to a smaller first fill diameter in vertical relationship to the first fill level as the first fill level rises during filling of the first flexible container to generate hoop forces; positioning a substantially planar member on top of the filled first radially flexible bulk container; filling a second radially flexible bulk container having a second large diameter with a plurality of particles to a second fill level; applying a stretch wrap to the second radially flexible bulk container to reduce the second large diameter of the second radially flexible bulk container to a smaller second fill diameter in vertical relationship to the second fill level as the second fill level rises during filling of the second flexible container to generate hoop forces; positioning the filled second radially flexible bulk container on the substantially planar member and on top of the filled first radially flexible bulk container.
