A lightweight transportable container is disclosed in which the wall, roof, and floor of the container are laminated panels bonded together to form a rigid monolithic structure. The container is formed of nonmetallic materials, is stackable, and has a payload more than eight times greater than the tare weight of the container. The container is particularly useful in hostile and extreme temperature environments and is designed to withstand the application of numerous forces from various directions, such as those typically applied, for example, in ISO certification testing.
