Introduction to 8021 aluminum foil
8021 aluminum foil alloy is one of GNEE's flagship products, with extremely high machinability, high tensile strength and tensile properties.
It also has excellent design properties, with minimal pinholes and an even, smooth matte finish. Currently widely used in soft pack batteries and other fields.
In addition, the 8021 aluminum foil alloy itself also has excellent moisture-proof, light-shielding and extremely high barrier capabilities. It is non-toxic, odorless and hygienic. Therefore, 8021 aluminum foil is also widely used in pharmaceutical packaging and food packaging.
8021 aluminum foil characteristics
Aluminum foil alloy 8021 has the advantages of good elongation, good deep drawing performance, good electrolyte corrosion resistance, and high heat sealing strength. The main advantage is that it is commonly used in deep drawing packaging materials.
8021 aluminum foil alloy has strong mechanical properties, high explosion resistance, puncture resistance and tear resistance.
High-quality aluminum foil alloy 8021 has a smooth surface, uniform color, no spots, no oil stains, and most importantly, no pinholes, so it has excellent moisture resistance, light-shielding properties and extremely high barrier capabilities.
8021 aluminum foil alloy application market
8021 battery film foil
Aluminum foil alloy 8021 is used in pouch batteries. Compared with traditional lithium-ion batteries, they are lighter, thinner, have longer cycle life, good safety, high energy density, stable point platform, excellent power performance, and are environmentally friendly and pollution-free.
Therefore, 8021 aluminum foil soft-pack batteries are widely used in electric vehicles, solar photovoltaic power generation systems, emergency lighting, portable power supplies, and mine safety equipment.
8021 Medicinal foil
Cold-formed 8021-O aluminum foil is the representative product of GNEE medicinal aluminum foil. 8021-O type cold-formed aluminum foil is a deep-drawn sealing packaging material.
GNEE strictly implements industry standards and conducts multiple tests for bacteria and mold. The heavy metal content of the 8021 aluminum foil alloy produced does not exceed 0.25ppm, ensuring safety and hygiene.
8021 Food foil
8021 aluminum foil has the characteristics of cleanliness and hygiene, and can be made into integrated packaging materials with many other packaging materials.
In addition, the surface printing effect of 8021 aluminum foil is better than other materials. Therefore, 8021 aluminum alloy can also be used in the field of food packaging.
