For Container Desiccant very large quantities of silica gel (and even more activated clay desiccant) would be needed to protect a shipping container and its contents from high humidity (container rain).
Calcium Chloride adsorbs 10 times more than silica gel and has been used as a desiccant in shipping containers for many years – BUT it has one big disadvantage:
Calcium chloride converts to liquid brine when it adsorbs moisture. If a pack is damaged and then leaks it can cause serious damage to the goods it is supposed to protect.
Dry Dragon uses NEW technology. There can be NO leakage because it BECOMES SOLID AS IT ADSORBS MOISTURE. (This is a feature of the special polymer used in it’s compilation).
