Aluminium Barrier Foil:
Aluminum Barrier Foil Packaging works on the principle of Climatic Packaging.
The Aluminum Barrier Foil acts as Barrier to the entry of Moisture inside the Packaging. It is sealed properly to ensure that outside Atmospheric moisture is not able to reach the metallic surfaces inside the Packaging.
The Climate inside the Packaging is Vaccumized to reduce the quantum of the Moisture and the Air.
Additional Moisture Absorbers and De-humdifiers like Silica Gel and Desiccant Clays are added inside the Packaging to attain relative humidity less than 40%.
Often VCI/VpCI materials are added for additional Corrosion Protection.
