What is Aluminum Barrier Foil?
Aluminum Barrier Foil comprises of 3 to 4 layers of different materials. These materials bond together with adhesive or extruded polyethylene and derive their properties from a strong construction as outlined in the below diagram.
The aluminum layer is extremely important in laminates. They are used in a wide variety of industries to provide both Dry Product Protection and Corrosion Prevention. Barrier Foil protects the integrity of any application where deterioration of the packaged product may take place due to:
- Moisture
- Oxygen Ingress
- U.V. Light
- Temperature Extremes
- Odors
- Chemicals
- Mold & Fungi Growth
- Grease & Oils
