ORBIS BulkPak Series collapsible bulk containers are made of high-density polyethylene to accommodate long and hard-to-fit components and parts. These containers collapse, when emptied out, for reduced return transportation costs. They feature solid side walls and a ventilated base for moisture resistance and facilitating easy cleaning. They come in a stackable design that allows the unit to be stacked securely atop each other to save warehouse space and are available in load capacities ranging from 1500 to 2500 lb.
