The stackable storage container is one of the key reasons why people have switched from cardboard to plastic. When the parts of plastic containers are made, they have to have what they term as draw, so they can get the plastic storage containers out of the mold. One benefit from having to have draw is; the pieces can be stacked on top of each other and if the forethought is put into the part, which it normally is, they become stackable with forms that fit into each other. The plastic storage container that is stackable remains very solid and rigid when placed on top of each other.
