Aluminum foil barrier packaging works on the principle of climatic packaging. The aluminum foil barrier 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. Applications: Aluminium foil barrier is used for the protection of machines, precision tools, components etc. against moisture and corrosion during sea transport and during storage. The climate inside the packaging is vaccumized to reduce the quantum of the moisture and the air.
