A container is a standardised unit of freight that is used to transport goods by sea, air, or land. Containers are typically made of metal and are designed to be loaded and unloaded with a minimum of handling, reducing the risk of damage to the goods and making it easier to transfer the cargo from one mode of transportation to another. Containers come in a variety of sizes, including 20-foot, 40-foot, and 45-foot units, and are often used in intermodal transportation, allowing for the transfer of cargo from ship to rail or truck without the need for re-handling.
