An Aluminium Liner is a high-barrier multilayer inner film combining aluminium foil with polyethylene layers to virtually eliminate moisture, oxygen, light and aroma ingress. The metal layer extends shelf life and blocks solvent vapours and odours.
Where to Use
Cocoa butter, milk powder, coffee beans, pharmaceutical APIs, fine chemicals, lithium-ion battery powders, and any hygroscopic or oxidation-sensitive granulate.
| Parameter | Value |
|---|---|
| Structure | Al foil / PET / PE co-extruded barrier film |
| Thickness | 110 – 160 µm |
| Water Vapour Transmission | <0.05 g/m²·24 h (38 °C / 90 % RH) |
| Oxygen Transmission | <0.02 cc/m²·24 h (23 °C / 0 % RH) |
| Certifications | FDA 21 CFR, EU 10/2011, Kosher, Halal |
The full metal barrier reduces moisture and oxygen transmission to near zero, greatly extending shelf life.
Any food or chemical raw material that is sensitive to moisture or oxidation.
Multilayer metal films have limited mechanical recyclability; they are directed to chemical recycling streams.
