Along with the introduction of new modules suitable for all of HC containers, truck pallets and air ULDs, we developed stacking pad that takes into account the product shape to increase storage efficiency in the height direction. By putting products, without any mutual interference, one by one within corrugated cardboard partitions and placing a sloped stacking pad in between, the products can be stacked without interfering with each other, thereby reducing the stacking height and improving loading efficiency by 33%.
