A flexible bladder is enclosed within a plurality of overlapping plastic sheets, with the ends of the sheets being secured in place by the weight of the flexible bladder, when filled. The preferred plastic is an extruded, twin-walled, fluted plastic based upon a polypropylene copolymer. In a alternative embodiment, a pair of hexagonal, coaxial sleeves of the preferred plastic have an internal bladder for shipping materials.
