Aluminum alloy 8079 Aluminum Foil with High Ductility: Expanded Applications in Flexible Packaging & Composite Films
The flexible packaging world wakes up to the high-ductility 8079 aluminum foil revolution. With 35 % higher elongation (≥12 %), zero pinholes, and gauge from 6 μm household to 200 μm industrial, this foil bends, seals, and protects like never before. From yogurt lids that survive -40 °C freezers to pharma blister packs that pass 1000 N puncture tests, 8079 is replacing multi-layer plastics at record speed. Zero BPA, zero microplastics, 100 % recyclable – the future of packaging is metal.

Hot Uses
High-ductility 8079 aluminum foil is rewriting flexible packaging rules from Nestlé USA to Pfizer EU. 35 % stretchier, 100 % greener, zero compromises – it seals, protects, and recycles like plastic never could. Food stays fresh for a decade, drugs survive polar shipping, and the planet gets a metal that comes back forever. The foil of the future is here, and it’s 8079.
