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.
Dri-Strip 1000 uses NEW technology. There can be NO leakage because it IMMEDIATELY CHANGES TO A HARD GEL AS IT ADSORBS MOISTURE. (Many other products convert to a hard gel – eventually – but there can be liquid in the pack for several days before they become solid).
6 Strips (1 carton) will protect a 20ft container for 6 weeks
12 strips (2 cartons) will protect a 40ft container for six weeks
This Super Desiccant is also available in 125g and 50g individual sachets.
R-Tech are the sole UK Distributor for these products.
