Application
The surface of aluminum foil is extremely clean and hygienic, and no bacteria or microorganisms can grow on it. Has good oxidation resistance, is a non-toxic, odorless, low density of 2.70; relatively low melting point; high boiling point; can be used in various high-temperature applications. Lightweight; malleable and ductile; can be easily shaped and formed into various shapes such as rods, sheets, foils, ribbons, and wires. packaging materials.
Aluminum foil is generally widely used:
- Lithium battery: Aluminum foil is used as a current collector in various lithium batteries to enhance adhesion and tensile strength.
- Food packaging: Aluminum foil is widely used as food packaging material because of its hygienic, non-toxic and tasteless characteristics.
- Industry: Aluminum foil is used in aerospace, construction and automotive industries due to its unique properties and light weight.
- Energy storage: used in energy storage devices such as fuel cells, power batteries, and energy storage power stations.

Advantages
- Hygienic and sterile: the surface of aluminum foil is clean, preventing the growth of bacteria and microorganisms, ensuring the safety of packaged food.
- Non-toxic, odorless and tasteless: Aluminum foil is safe for direct contact with food and will not cause any health risks to the human body. Can retain the original flavor of food.
- Moisture Barrier: Aluminum foil prevents packaged food from drying out or shrinking, maintaining its freshness and moisture content.
- Grease Resistance: Does not allow grease or oil to penetrate, maintaining package integrity and preventing leaks.
- Light-shielding and UV-resistant: Aluminum foil is opaque and protects against sunlight, making it suitable for light-sensitive products.
- Versatility: Aluminum foil can be easily formed for packaging products of various shapes and sizes.
- Hardness and Tensile Strength: Aluminum foil has high hardness and tensile strength, making it suitable for various packaging applications.
- Tear Resistance: Although aluminum foil has a high tensile strength, it can tear relatively easily.
