A container in normal use should at least be waterproof, without any risk of rain leakage or cracks. Ensure that all containers should be inspected before loading, especially not to overlook the easily damaged locations such as container doors
Check the tightness of the container. We know for sure that no container is completely airtight, but a good container should only allow moisture and air to circulate slowly between the inside and outside of the container. This phenomenon is called "container breathing". It plays a significant role in reducing the entry of external moisture into the container in a normal environment.
If you are shipping dry goods, please seal all the vents of the container, but if it is agricultural products, you may need an environment to keep the vents.
However, because the container is shipped by sea during the day, the internal temperature can be as high as 60 degrees Celsius. In such a high temperature and a relatively closed environment, we can imagine that the raw materials used for packaging will evaporate a lot of water vapor. The moisture content of the air in the environment is very large. When it comes to night, the temperature inside the container/container will slowly drop, and under low temperature conditions, the air's ability to hold water vapor is relatively low. Obviously, we will know that in the air with high temperature and high water content during the day, a part of the water vapor will adhere to the side walls of the container and the inner surface of the cargo in the form of condensed water (such as shrink film and carton and shrink film between woven bags). The other is that if there is too much condensate on the top of the container, it will drip down. This phenomenon is called container rain in colloquial terms.
At this time, we will advise customers to place several chunwang container desiccants in the container to prevent container rain. Chunwang container desiccant is a long, flat, moisture-proof and dehumidifying product designed with a firm hook. The whole desiccant can just fit tightly in the groove on the inner wall of the container without occupying the cargo loading space. Chunwang desiccant The super moisture absorption ability enables it to quickly absorb the moisture in the surrounding environment and the moisture evaporated into the air by the cargo itself and packaging accessories, reducing the humidity inside the container, avoiding visible and hidden condensation, and ensuring that the internal climate environment of the container is always It is in a dry state of dynamic equilibrium, so as to protect the goods to reach the destination safely and dry.
