As an essential tool for transportation and construction, containers involve many key technologies. Let's delve into the key technologies of containers.

Firstly, container structure technology is one of the keys. This includes design, material selection, welding technology, etc., affecting the strength, stability, and durability of containers.

Secondly, container sealing technology is crucial. Good sealing design and technology can ensure the safety and dryness of goods inside containers, preventing moisture damage.

Additionally, container lifting technology is also critical. Lifting involves equipment selection, operation procedures, safety measures, etc., directly affecting the efficiency and safety of container loading and unloading.

Furthermore, container corrosion prevention technology is also important. Due to prolonged exposure to maritime or humid environments, corrosion prevention technology can effectively extend the service life of containers.

Lastly, container intelligent technology is gaining attention. Through smart sensors, remote monitoring, etc., real-time monitoring and management of containers can be achieved, improving transportation efficiency and cargo safety.

In summary, key technologies of containers include structure, sealing, lifting, corrosion prevention, and intelligence, providing reliable guarantees for container transportation and applications.
