Classification of Aluminum Foil

[Keganhirl]

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.

What is the production of thin aluminum foil?
① Plain foil: after rolling without any other processing of aluminum foil, also known as light foil.
② Embossed foil: aluminum foil with various patterns pressed on the surface.

③ Composite foil: combine aluminum foil with paper, plastic film, and cardboard to form a composite aluminum foil.
④ Coated foil: the surface of aluminum foil coated with various resins or lacquers.
⑤ Colored aluminum foil: the surface of aluminum foil coated with a single color.

⑥ Printing aluminum foil: aluminum foil through the printing on the surface to form a variety of decorative patterns, patterns, text or tableau, can be a color, up to 12 colors.
Soft aluminum foil can also be further pressed into a four-foil,used for high-end decoration.

[Keganhirl]

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

1 thick foil ("heavy gaugefoil"): a foil having a thickness of 0.1 to 0.2 mm.

2 "medium gauge foil": a foil having a thickness of 0.01 mm and less than 0.1 mm/.

3 "light gauge foil": The so-called double-zero foil is a foil with two zeros after the decimal point in its thickness, usually aluminum foil with a thickness less than 0.01, ie 0.005~0.009mm aluminum foil . In foreign countries, an aluminum foil having a thickness of ≤ 40 ltm is sometimes referred to as a "light gauge foil", and an aluminum foil having a thickness of > 40 btm is collectively referred to as a "heavy gauge foil".



shape

The aluminum foil can be divided into a rolled aluminum foil and a sheet aluminum foil according to the shape. Most of the aluminum foil deep-processing wool is supplied in rolls, and only a few hand-made industrial packaging uses sheet-like aluminum foil.



Aluminum foil can be classified into hard foil, semi-hard foil and soft foil according to the state.

1 Hard foil: Aluminum foil that has not been softened (annealed) after rolling, and has no residue on the surface without degreasing. Therefore, the hard foil must be degreased before printing, lamination, coating, and can be used directly if it is used for forming.

2 semi-hard foil: aluminum foil hardness (or strength) between the hard foil and the soft foil, usually used for forming.

3 soft foil: aluminum foil which is softened after being fully annealed after rolling, the material is soft and there is no residual oil on the surface. Soft foils are used in most applications, such as packaging, composites, and electrical materials.



surface condition

The aluminum foil can be divided into a light aluminum foil and a double-sided aluminum foil according to the surface state.

1 Single-sided aluminum foil: Double-rolled aluminum foil, which is bright after splitting, and the surface is black. Such aluminum foil is called a light aluminum foil. The thickness of one side of the aluminum foil usually does not exceed 0.025 mm.

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



Processing status

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

1 plain foil: aluminum foil without any other processing after rolling, also called light foil.

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

3 composite foil: a composite aluminum foil formed by laminating aluminum foil and paper, plastic film and cardboard.

4 coated foil: aluminum foil coated with various types of resin or lacquer on the surface.

5 color aluminum foil: the surface is coated with a single color of aluminum foil. 6 Printing aluminum foil: Aluminum foil which is formed by printing various patterns, patterns, characters or pictures on the surface, which can be one color, up to 12 colors.
