How can aluminum foil classification?
Third, according to the surface state
Press the foil surface state can be divided into one side and smooth on both sides light aluminum foil.
1. The single-sided light aluminum foil: doublet rolling of aluminum foil, shiny side after sub-volumes, - face black hair, so called side light aluminum foil. Side light foil thickness usually does not exceed o. 025mm.
2. The double-sided light aluminum foil: single rolled aluminum foil, two paintings and roller contact with both sides of the aluminum foil due to the roll surface roughness is divided into different mirror two surface light aluminum foil and a general two surface light aluminum foil. Two surface light foil thickness generally not less than 0.01mm.
Press plus state
Aluminum foil can be divided according to the shape of a roll of aluminum foil and a sheet of aluminum foil. Aluminum foil deep processing wool was rolled supply most, only a few handicraft packaging occasions with a sheet of aluminum foil.
Aluminum foil can be divided according to the state of a hard foil, semi-rigid foil and soft foil.
1. Hard foil: After rolling without softening treatment (annealing) of aluminum foil, without degreasing, surface Bu there is a residual Shantou. So hard foil printing, laminating, coating must be degreased before, if used for forming can be used directly.
2. The semi-rigid foil: aluminum foil hardness (or strength) of the aluminum foil rigid foil and soft foil is commonly used for forming.3. The soft foil: After full annealing after rolling and become soft aluminum foil, soft material, no residual surface. Most applications, such as packaging, composite, electrical materials, use soft foil.
Second, according to the shape
Aluminum foil can be divided according to the shape of a roll of aluminum foil and a sheet of aluminum foil. Aluminum foil deep processing wool was rolled supply most, only a few handicraft packaging occasions with a sheet of aluminum foil.
First, according to the thickness
Differences can be divided according to the thickness of aluminum foil thick foil, single zero foil and double zero foil.
1. Foil thickness: 0.1 ~ 0.2mm thick foil.
2. The single zero foil: thickness of 0.01mm and less than 0.1mm / foil.
3. The double zero foil: a so-called double zero foil after its thickness is in mm unit of measure of the decimal point two zero foil, usually aluminum foil of a thickness of less than 0.01, namely 0.005 ~ 0.009mm aluminum foil.
Fourth, the foil can be divided according to the state plus the prime foil, embossed foil, a composite foil, foil coating, color printing aluminum foil and aluminum foil.
1. Su foil: After rolling without any other processing of aluminum foil, also known as foils.
2. The embossing foil: aluminum foil embossed with various patterns on the surface.
3. The composite foil: aluminum foil and paper, plastic film, cardboard fit in - a composite formed from aluminum foil.
4. Coating foil: there are various types of resin coated on the surface of aluminum foil or lacquer.
5. colored foil: aluminum foil coated with a single color on the surface. ⑥ printing Foil: foil formed by printing a variety of patterns, designs, text or picture on the surface, can be a color, up to a maximum of 12 colors.
