Overview of 8079 Kerajang aluminium

8079 Aluminum Foil belongs to the 8xxx series of wrought aluminum alloys, characterized by very high aluminum content (≥98.1 %) and small additions of iron and silicon that enhance strength and ductility.
It exhibits excellent barrier properties—moisture resistance, gas tightness, and light blocking—to protect sensitive products.
The alloy’s bright silver-white surface also allows for decorative printing and patterning, making it ideal for high-end packaging applications.
