Tuck end boxes are usually referred to as crates. This is because the term is actually derived from shipping regulations in the USA. These boxes are used for the transportation of perishable items. The term "crate" comes from the tendency of the boxes to collapse in on themselves when they reach a certain weight. In this way, they become difficult to move and more expensive to ship. For this reason, many companies and individuals ship their perishables and possessions using Tuck Boxes Wholesale in the USA.
