What is meant by the "fourth packaging" in the packaging classification?

The term "fourth packaging" refers to the transportation phase in the logistics and supply chain process, where goods are moved from one place to another using various modes of transport. This includes vehicles, ships, and aircraft specifically designed for carrying goods. In the context of packaging classification, the first three levels typically involve inner packaging, outer packaging, and secondary packaging that focus on protecting the product itself and facilitating handling within storage and retail environments.

The fourth packaging, however, is broader and encompasses all the logistic aspects of transporting packaged goods over distances, ensuring they arrive at their destination safely. This classification highlights the importance of considering the entire journey of a product, from its original packaging all the way to its final delivery, thus integrating not only the product's core protection but also its safe transit in different transportation modes.
