8021 Aluminum Foil for Food Packaging plays a key role in the manufacture of lithium ion batteries. As a collector, it provides a conductive path for the positive and negative electrodes of the battery, ensuring that current flows correctly within the battery. As the current collector pole, aluminum foil is responsible for collecting the current generated by the positive electrode.
8021 Aluminum Foil for Food Packaging is a hot stamping material made from metallic aluminum that is directly calendered into a thin sheet, and is also known as fake silver foil because its stamping effect is similar to that of sterling silver foil. Aluminum has a soft, malleable texture and a silvery-white luster, and is therefore used in a wide variety of packaging and decorative applications.

GNEE adopts the double-roll casting and rolling method:
The advantages of double-roll casting and rolling method are high production efficiency, good product quality and low cost. Since the liquid aluminum is poured directly between the two rotating rollers, it can be quickly cooled and solidified into plates, avoiding the problem of oxides and inclusions produced during the heating process of the ingot. In addition, the two-roll casting and rolling method can produce thinner plates, thus reducing multiple passes of rolling and annealing treatments and shortening the production cycle.
