Picture of a non-sterilized iron packaging box

Quick answer：

A non-sterilized iron packaging box refers to a container made of iron that is not heat-treated to kill pests. It is commonly used for shipping goods, particularly those that do not require sterilization. These boxes are often used in the agricultural sector for transporting grains and other food products. The term 'non-sterilized' indicates that the box has not undergone a process to eliminate pests, which is important for maintaining the quality and safety of the contents during transportation.
