8079 Aluminum Foil Jumbo Rolls
8079 aluminum belongs to the aluminum-iron-silicon alloy series. A distinctive feature of its chemical composition is the presence of relatively high concentrations of iron (Fe) and silicon (Si); typically, the iron content ranges from 0.7% to 1.3%, while the silicon content falls between 0.05% and 0.30%. This specific alloy formulation endows 8079 aluminum foil with high strength, excellent elongation, and exceptional plasticity, enabling it to demonstrate outstanding formability during processing. In summary, its tensile strength is significantly higher than that of standard aluminum foil.

In food packaging applications, 8079 aluminum foil offers excellent moisture resistance, light blocking, and aroma retention properties, effectively extending shelf life. Its elegant silver-white metallic appearance also enhances the visual appeal and premium feel of packaged products.
- Pharmaceutical Packaging
In pharmaceutical applications, 8079 foil meets the stringent sealing requirements of PTP blister packaging. It also supports advanced printing processes for clear and diverse product identification, fully complying with strict pharmaceutical regulatory standards for safety and traceability.
- New Energy Battery Pouch Cells
With the rapid growth of the new energy industry, 8079 foil is increasingly used in lithium battery pouch cells. Its high strength and good conductivity help improve energy density and safety performance, while its lightweight characteristics align with the automotive industry’s demand for weight reduction in electric vehicles.
- Industrial Applications
In industrial fields, 8079 aluminum foil is widely used in components such as air conditioner heat exchanger fins and cable shielding layers. Its excellent heat resistance and corrosion resistance enable stable performance in complex and demanding industrial environments.
Post-processing
8079 aluminum foil can be laminated with materials such as PE or EVA to create airtight packaging structures. It demonstrates high thermal resistance (capable of withstanding pasteurization and UHT sterilization) and corrosion resistance, remaining stable and non-leaching within acidic or alkaline food environments.
Global Certification Standards
The material has obtained certifications such as FDA 175.300 (USA), EC 1935/2004 (EU), and REACH, ensuring full compliance with regulations in export markets. These certifications mandate that—under specified conditions (e.g., high temperatures, acidic or alkaline environments)—the migration levels of substances from the material remain significantly below established safety limits, thereby systematically eliminating potential safety risks.
