Analysis of the classification of aluminum foil sheet for sale Haomei

Because of its excellent properties, aluminum foil sheet is widely used in food, beverages, cigarettes, medicines, photographic plates, household daily necessities, etc., and is usually used as its packaging material, electrolytic capacitor material, thermal insulation material for buildings, vehicles, ships, houses, etc.; it can also be used as decorative gold and silver thread, wallpaper and various stationery prints and decoration trademarks of light industrial products, etc. Let's take a look at the classification of aluminum foil sheets.

1. Thickness

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

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

②Single zero foil: foil with a thickness of 0.01mm and less than 0.1mm/.

③Double zero foil: Double zero foil means that there are two zero foils after the decimal point of thickness mm, usually aluminum foil with a thickness of less than 0.01, that is, 0.005~0.009mm aluminum foil.

2. Shape

According to the shape, aluminum foil sheets can be divided into roll aluminum foil and sheet aluminum foil. Most of the aluminum foil deep processing wool is supplied in rolls, and only a few handicraft packaging occasions use sheet aluminum foil.

According to the state, aluminum foil for sale can be divided into hard foil, semi-hard foil and soft foil.

① Hard foil: The aluminum foil sheet that has not been softened after rolling has residues on the surface when it is not degreased. Therefore, hard foils must be degreased prior to printing, lamination and coating, and can be used directly if used for forming.

②Semi-hard foil: The hardness (or strength) of the aluminum foil between the hard foil and the soft foil, which is usually used for forming.

③Soft foil: The aluminum foil sheet that is completely annealed and softened after rolling is soft and has no residual oil on the surface. Soft foils are used in most applications such as packaging, composites, electrical materials, etc.

3. Surface state

aluminum foil sheets can be divided into single-sided light aluminum foil and double-sided light aluminum foil.

①Single-sided smooth aluminum foil: double-rolled aluminum foil, one side is bright and one side is black after sub-rolling. The thickness of single-sided smooth aluminum foil is usually not more than 0.025mm.

②Double-sided smooth aluminum foil: A single rolled aluminum foil, both sides are in contact with the roll. The two sides of the aluminum foil are divided into mirror double-sided smooth aluminum foil and ordinary double-sided smooth aluminum foil due to the different surface roughness of the roll. The thickness of double-sided light aluminum foil for sale is generally not less than 0.01mm.
