2. Why Use Desiccants?
You know the two biggest enemies of any Packaged Products?
Moisture & Oxygen
Lethal potential to damage metals, drugs, woods, plastics, glass,
Foods, Cloth, Paper, Leather…
The effects of Moisture & Oxygen are: Simply Devastating!
On the product life, presentability, functionality & performance,
on profits & finally on the repute of manufacturer/exporter
3. Strategy For Moisture Control....
In Packaged Goods
Reduce! (by MAP & Vacuum)
Eliminate (by Desiccants)
Prevent (by Barrier Packaging)
4. Something About Moisture
• Present in the air in the form of Vapors (Gas
Phase) having more penetrative &
damaging ability than liquid form. We
measure moisture in % RH w.r.t.
• Temperature and is dynamic through out
the year. Also the moisture in compressed
air flow is measured as dew point.
• Affects integrity of packaging materials,
packaged products, bacterial growth, bad
odour etc…

Silica Gel Desiccants Cargo Dry Paks Oxygen Absorbers
7. How are Desiccants Rated?
• Packaging experts face a confusing array of variables
when selecting moisture adsorbents partly because
moisture control is a multifaceted challenge. There are
four sources of water contamination in a closed
container or package:
• Water vapor in the air inside the package.
• Water vapor adsorbed by the materials inside the
package Water vapor on the walls of the package
• Permeation of water vapor into the package.
8. Quality Parameters-Desiccants
• Should have very high adsorption capacity
• Should have low residual moisture (LOD)
• The desiccant material should have neutral pH (6.5-7.5), inert & non-toxic in
nature
• Should be packed in non-dusting, non-tearable, non-lintable packing materials
preferably spun-bonded olefins
• The packet material should not have wetting effect on surface upon saturation
• Should be confirming to International standards CFR/EU compliant, MIL-D
specs, JDEC-033, FDA etc…
• Should be active (RTU) when using.
• The packet material should be permeable to moisture
• Desiccant must have moisture holding capacity at higher temperatures below
evaporation point of water Desiccant should not release water upon saturation
9. Do's
Do & Don'ts-Desiccants
Dont's
• Always use desiccants when you
are ready to pack your goods &
seal immediately
• Place the desiccants at different
locations inside the package &
near the possible sources of air
permeation
• Store in the original container
away from darkness
• Look at the HIC placed inside the
desiccant container before using
• Expose the desiccants unnecessarily
• Remove the HIC card from the
original container
• Use over-exposed desiccant pouches
• Punch holes in the desiccant packets
