Introduction to aluminum foil type division and use

Aluminum foil is a soft metal film. It not only has the advantages of moisture -proof, dense gas, shielding, abrasion resistance, flavor, non -toxic and tasteless, but also because of its elegant silver -white luster, which is easy to process a variety of beautiful patterns and beautiful patterns and patterns and colorful patterns and colorful patterns and colors. Pattern is more likely to be favored by people. The aluminum foil has the advantages of light quality, closedness and covering. It is currently mainly used in packaging, electromechanical and construction.

Aluminum foil can be divided into thick foil, single zero and double foil.

1. Thick foil: Foil with a thickness of 0.1 to 0.2mm.

2. Single -zero foil: thickness of 0.01mm and foil less than 0.1mm.

3. Double zero foil: The so -called double -zero foil is two zero aluminum foil after the thickness of the MM as the measurement unit, usually aluminum foil with a thickness of less than 0.01, that is, an aluminum foil of 0.005 ~ 0.009mm.

Aluminum foil can be divided into hard foil, semi -hard foil and soft foil.

1. Hard foil: Aluminum foil that is not softened (annealing) after rolling, hard foil must be subtracted before printing, fit, and coating. If it is used for forming processing, it can be used directly.

2. Semi -hard foil: aluminum foil hardness (or strength) aluminum foil between hard foil and soft foil is usually used for forming processing.

3. Soft foil: After rolling, the aluminum foil that has been sufficiently reduced, the material is soft, and there is no residual oil on the surface. At present, most of the application areas, such as packaging, composite, electrical materials, etc., are soft foil.

Aluminum foil can be divided into one -sided light aluminum foil and two -sided light aluminum foil.

1. One side of light aluminum foil: double -rolled aluminum foil, the side roll is shiny, —the surface is black, such aluminum foil is called a light aluminum foil. The thickness of light and aluminum foil usually does not exceed 0.025mm.

2. Both sides of light aluminum foil: single -rolled aluminum foil, two paintings and roll contacts. The two sides of the aluminum foil are divided into mirroring aluminum foil and ordinary two -sided light aluminum foil due to different roll surface roughness. The thickness of the two -sided aluminum foil is generally not less than 0.01mm.

Due to its excellent characteristics, aluminum foil is widely used in food, beverages, cigarettes, medicines, photographic bottom plates, family daily necessities, etc., usually used as insulation materials for its packaging materials, electrolytic capacitors, buildings, vehicles, ships, houses, etc.
