Barrier Film Bags
The laminated barrier film provides maximum protection against moisture, corrosion and radiation. This is a triple-layer film consisting of a polyester film on the outside, an aluminium foil in between, and a high-density polyethylene inner layer. The barrier film bag, if properly packaged, can protect the contents from moisture penetration from outside for many months. Barrier bag packaging is hermetically sealed and a slight vacuum is created inside the casing to reduce the volume of air contained, in order to eliminate the amount of relative humidity as much as possible. A suitable quantity of dehydrating material is placed inside the box, which absorbs the moisture from the material itself and the moisture in the air at the time of closing.
