Stackable pallets have bottom support, allowing them to be stacked on top of another loaded pallet, providing stability during storage and transport. A solid platform on the bottom of a stackable pallet allows it to double stack with product and other pallets. When loaded, they are intended for shelving and storage.
Many types of pallets cannot be stacked; some have irregularly shaped lower surfaces that would damage the loads on which they would rest. Stackable pallets frequently have a flat, minimally textured lower surface that can be placed on top of loads that are uniformly flat. Because stackable pallets save floor space by stacking vertically, they must be fully supported when loaded and in racking.
