The thickness of the

According to the thickness difference, aluminum foil can be divided into thick foil, single zero foil and double zero foil.

Heavy gaugefoil: foil with thickness of 0.1 ~ 0.2mm.

Vacuum single zero foil (" medium gauge foil ") : foil with a thickness of 0.01mm and less than 0.1mm/.

The so-called "light gauge foil" is the foil with two zeros behind the decimal point when its thickness is measured in mm. It is usually aluminum foil with a thickness of less than 0.01, i.e., 0.005~0.009mm. In foreign countries, the aluminum foil with a thickness of 40ltm or less is sometimes called "light gauge foil", while the aluminum foil with a thickness of >40btm is called "heavy gauge foil".

The shape of

According to the shape, aluminum foil can be divided into rolled aluminum foil and sheet aluminum foil. Deep processing of aluminum foil wool most of the supply of coil, only a few handicraft packaging occasions use sheet aluminum foil.

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

Hard foil: unsoftened (annealed) aluminum foil after rolling, without degreasing, surface coating shantou. Therefore, hard foil must be degreased before printing, bonding and coating, and can be used directly if it is used for forming.

Aluminum foil: aluminum foil with a hardness (or strength) between hard and soft foil, usually used in forming process.

Flexural foil: rolled aluminum foil that is softened by sufficient annealing and has a soft material and no residual oil on the surface. Soft foil is used in most applications, such as packaging, composite, electrical materials, etc.

Surface state

According to the surface state, aluminum foil can be divided into one side and two sides.

Single surface smooth aluminum foil: double rolled aluminum foil, rolled after one side bright, - surface hair black, such aluminum foil is known as one side light aluminum foil. The thickness of a piece of bare aluminum foil usually does not exceed 0.025mm.

Aluminum foil two-sided: single sheet rolled aluminum foil with two sides in contact with the roll. Due to different surface roughness of the roll, two sides of aluminum foil can be divided into two sides of mirror aluminum foil and two sides of ordinary aluminum foil. Generally, the thickness of two-sided aluminum foil is not less than 0.01mm.

The processing status

According to the processing state, aluminum foil can be divided into plain foil, embossed foil, composite foil, coated foil, colored aluminum foil and printed aluminum foil.

White and white foils: aluminum foils rolled without any other processing, also known as optical foils.

String foil: aluminum foil embossed with various patterns on the surface.

Residues foil: the composite foil formed by attaching aluminum foil to paper, plastic film, and cardboard.

Coating foil: aluminum foil coated with various resins or paints.

Mutually coloured aluminum foil: aluminum foil with a single color painted on the surface. Aluminium-printing foil: aluminum foil printed on a surface to form patterns, patterns, words, or images can be a color, up to 12 colors.

Soft aluminum foil can also be further pressed into zero foil for high-end decoration.
