1. Data source: Chunwang Environmental Protection (reprint please indicate the source)
2. Port of departure: SUVA, FIJI Passage: Oakland (New Zealand) Pacific Long Beach (USA) Destination port: California (USA)
3. Container type: 6 20 'containers from 6 shipping companies.
4. Loading cargo: Bottled Fiji water (carton packing)
5. Product: Container desiccant (raw material: calcium chloride mixture, inner non-woven fabric + outer PP non-woven fabric + color card packaging)
6. Record of container temperature during shipping:
(Yellow line: no desiccant, RH≈48% -92%, about 75% at port
Blue line: place desiccant, RH≈40% -72%, arrival at port is about 50%)
8. During the ocean transportation of containers, the temperature difference between day and night is huge. The hot air, which is rich in moisture during the day, decreases with temperature at night. If it is not controlled, water droplets (commonly known as container rain) may form. Causes the packaging box to break and even erode the product.
9. Conclusion: Through the tracking comparison between with container desiccant and without container desiccant, we can find that in the same period and under the same conditions, the humidity of the container with the appropriate container desiccant is significantly lower.
