Strong barrier property: It has extremely strong barrier property and can completely block all kinds of light (electromagnetic waves), air, moisture and bacteria, and can effectively prevent food from being damp, oxidized and deteriorated, and has an excellent fresh-keeping effect.

1. Strong barrier property: It has extremely strong barrier property and can completely block all kinds of light (electromagnetic waves), air, moisture and bacteria, and can effectively prevent food from being damp, oxidized and deteriorated, and has an excellent fresh-keeping effect.
2. Strong antibacterial properties: Due to the antibacterial properties of high-purity aluminum, it is difficult for bacteria or microorganisms to survive on the surface of aluminum foil that has been treated at high temperature. In developed countries, aluminum foil has already become a food packaging material and household daily necessities.
3. Good thermal performance: aluminum foil has a high reflective ability to light and heat, and has good thermal conductivity. It is suitable for both heating and heat preservation of food; it can be used normally in the range of -200°C to +300°C.
4. Good plasticity: Aluminum foil has both high specific strength and good ductility, and is relatively easy to shape. It is suitable for packaging various types of products and is also suitable for making various containers.
5. Lightweight and beautiful color: Aluminum is a light metal, and its specific gravity is less than one-third of that of steel and copper. It has a bright silvery white, high-end and exquisite metallic luster, and can also be processed and printed with various gorgeous patterns.
6. Non-toxic and tasteless: It can be in direct contact with food without any hidden danger to human health, and will not cause any peculiar smell or adverse effects on the packaged food.
7. Anti-oxidation: There is an extremely thin and dense oxide film on the surface, which does not "rust" and has self-protection properties.
8. Recyclable: Aluminum can be recycled and reused, with low energy consumption and high value, and is very friendly to the environment.

Anti-corrosion process of aluminum foil

The main cause of corrosion is that the product is damp or exposed to water during the production process and distribution process. Therefore, controlling the production of corrosion waste is mainly to prevent aluminum foil from contacting water.

Care and Maintenance of Aluminum Plates

Special attention should be paid to the selection of suitable detergents. A basic principle is: must use neutral detergents! Please do not use strong alkaline detergents such as potassium hydroxide, sodium hydroxide or sodium carbonate, strong acidic detergents, abrasive detergents and baking varnish soluble detergents.

Processing technology of aluminum coil

Silicon has a corrosive effect on cemented carbide. Although aluminum alloys with more than 12% Si are generally called high-silicon aluminum alloys, it is recommended to use diamond tools, but this is not absolute, and the destructive power of the tools will gradually increase as the silicon content gradually increases. Therefore, some manufacturers recommend the use of diamond tools when the silicon content exceeds 8%.
