What is the technique of stacking items on top of one another called?

The technique of stacking items on top of one another is commonly referred to as block stacking. This method is often utilized in warehousing and storage environments where items are stacked directly on top of one another in a stable and organized manner without the use of pallets or shelving.

Block stacking has the advantage of maximizing vertical space and allows for the effective storage of a high volume of items in a compact area. To maintain stability and safety, it is important to consider factors such as the weight and shape of the items being stacked, as well as their material properties.

Other methods mentioned, such as palletizing, involve stacking items on a pallet for easier transportation or storage, while tier stacking generally refers to stacking items in tiers or levels, which may not necessarily mean they are stacked directly on top of one another. Layer stacking might imply a similar idea but is less commonly used as a specific term in comparison to block stacking.
