Since July, the temperature across the country has hit a new high, with temperatures in many cities reaching over 38-40 degrees Celsius, which is the dog days of summer. It is often said that the dog days are the most sultry and humid time of the year. The dog days occur between Minor Heat and End of Heat (mid-July to mid-August in the Gregorian calendar), and the three volts are divided into first volts, middle volts and last volts. The dog days are characterized by high temperature, low pressure, high humidity and low wind speed."Fu" means that Yin qi is forced by Yang qi to hide underground, and the time of Fu qi is determined by the date of the solar term and the date of the dry branch day. The time of three volt is usually 30 or 40 days. In this hot and humid period, the export goods packaging have a part of the moisture, in the experience of container shipping process, affected by the temperature difference between day and night, it is easy to form water vapor in the cargo packaging, forming "container rain" in the inner wall of the container, so that the goods or packaging carton is damp and mildew. If the calcium chloride desiccant is put in the packaging to remove the moisture adsorbed by the cargo itself during the production, and the container desiccant is hung inside the shipping container to remove the moisture of the carton, which is a good technical means for the shipping container goods to prevent the formation of the container rain. 

When packaging desiccant, it is recommended to choose calcium chloride desiccant, with gel calcium chloride desiccant, can adsorb 200% of its own weight of moisture, is a strong adsorption capacity and natural degradation of relatively environmental friendly desiccant, under the removal of the same moisture, the cost performance is very high in the type of desiccant. Container desiccant with calcium chloride as the main adsorption component is also very cost-effective in the type of container desiccant. 

Therefore, in the dog days of summer in July and August, calcium chloride desiccant or container desiccant are all effective and cheap technical measures worth using in container moisture-proof in cargo packaging and Marine transportation of goods.
