Aluminum Foil Films:
A composite film, which use adhesive or coating methods to bond three, four layers or multiple layers together.
The first layer: The surface layer can ensure the strength and puncture resistance of the packaging bag within a certain temperature and range.
Second layer: Aluminum foil barrier layer. The main function is to prevent moisture, oxygen and light.
Third layer: The inner layer is the heat sealing layer.
It can ensure that the relative humidity in the packaging bag is less than 40%, and the moisture-proof effect is 80 times than the ordinary polyethylene.
There are various specifications, sizes and materials of composite films for customers to choose.
It has good protective properties: oxygen resistance, moisture resistance, puncture resistance, high strength, high toughness and can be breathable in one or both directions, resistant to strong ultraviolet rays, such as oil, grease, and acid-base substances.
