Aluminum foil has a variety of classifications, different aluminum foil also has a different role. The following simple classification of aluminum foil, according to the thickness of aluminum foil, shape, state or material can be classified.

I. Classification of aluminum foil

Aluminum foil has a variety of classifications, different aluminum foil also has a different role. The following simple classification of aluminum foil, according to the thickness of aluminum foil, shape, state or material can be classified.

Aluminum foil According to thickness difference can be divided into thick foil, single 0 foil and double 0 foil. ① thick foil: thickness of 0 1~0.2mm foil. ② Single 0 Foil: thickness of 0.0lmm and foil less than 0.1mm. ③ Double 0 Foil: The so-called double 0 foil is in its thickness of MM as the unit of measurement when the decimal point has two zero foil, usually a thickness of less than 0.0075mm aluminum foil. When expressed in English, the thick foil is called "heavy gauge foil '", a single 0 foil called "Medium gauge foil", and a double 0 foil called "light gauge". Foreign sometimes the thickness of ≤40ltm aluminum foil called light gauge foil, and the thickness of the aluminum foil >40BTM collectively known as heavy gauge foil.

Aluminum foil by shape can be divided into rolled aluminum foil and flaky foil. Aluminum foil deep processing of wool most of the roll-like supply, only a few handicraft packaging occasions only with flaky foil.

Aluminum foil by the state can be divided into hard foil, semi hard foil and soft foil. ① hard foil: After rolling without softening treatment (annealing) of aluminum foil, without degreasing treatment, the surface of the residual shantou. Therefore, the hard foil in the printing, laminating, coating must be done before degreasing treatment, if used for forming processing can be directly used. ② semi-hard foil: aluminum foil hardness (or strength) between the hard foil and the soft foil, usually used for forming processing. ③ Soft foil: After the rolling after full annealing and softened aluminum foil, the material is soft, the surface is not residual oil. At present, most areas of application, such as packaging, composite, electrical materials, are used in soft foil. Aluminum foil According to the surface state can be divided into one side light (single-sided light) aluminum foil and two-sided light (double-sided light) aluminum foil. ① one side of the light aluminum foil: Double rolled aluminum foil, after the volume of light, one side of the black, such aluminum foil is called a light aluminum foil. The thickness of a light foil usually does not exceed O. 025mm. ② Two-sided light aluminum foil: Single sheet rolling aluminum foil, both painting and roll contact, aluminum foil on both sides of the surface roughness of the rollers are divided into mirror two surface light aluminum foil and ordinary two-sided light aluminum foil. Two surface light aluminum foil thickness is generally not less than 0.01mm.

Aluminum foil According to the state can be divided into the element foil, embossed foil, composite foil, coated foil, color aluminum foil and printed aluminum foil. ① foil: After rolling, no other processing of aluminum foil, also known as light foil. ② Embossed Foil: The surface is embossed with various patterns of aluminum foil. ③ Composite Foil: The aluminum foil and paper, plastic film, cardboard laminating in-formed composite aluminum foil. ④ coated Foil: The surface is coated with various types of resin or lacquer foil. ⑤ Colored aluminum Foil: the surface is coated with a single color of aluminum foil. ⑥ Printing aluminum Foil: by printing on the surface to form a variety of patterns, patterns, text or picture of the aluminum foil, can be a color, up to 12 kinds of color.

Aluminum foil with light weight, airtight and cladding of good and so on-series of advantages, therefore, in many sectors of the national economy and People's daily life to obtain a wide range of applications, but at present it is mainly used in packaging, electromechanical and construction of the three major areas.

Second, the domestic aluminum foil industry present situation and the development foreground analysis

With the development of national economy and the improvement of people's living standard, the production and production capacity of aluminum foil in China is developing rapidly. The application field of aluminum foil is also expanding, and the demand of aluminum foil in all fields is increasing rapidly, especially in the field of packaging, which has become an important part of the rapid development of China's aluminum foil industry.

China's aluminum foil industry product structure will be further rationalized, high-grade aluminum foil production proportion will continue to increase, the international competitiveness of products continue to improve, overall to a wider, thinner direction, in particular, the 0.005 mm thickness of the following aluminum foil will achieve scale production, and in the packaging industry in a large number of applications. For such as double 0 foil, air conditioner foil, medicine foil and other important varieties and some special varieties, such as high voltage anode foil, will be developed to the direction of High-tech level. China's aluminum foil market demand is the air-conditioning foil, smoke foil, decorative foil, cable foil, the above four varieties accounted for more than 70% of the demand for aluminum foil.
