(I) air conditioning foil

Air conditioning foil is a special material for making air conditioners with heat exchanger fins. The early air conditioner foil is plain foil. In order to improve the surface properties of the plain foil, the hydrophilic foil was formed by coating the inorganic coating and the hydrophilic organic coating before forming. Hydrophilic foil makes up 50% of the total amount of air conditioning foil, and its use proportion will be further improved. There is also a kind of hydrophobic foil, so that the fin surface has the function of hydrophobic, to prevent the condensation water adherent. The technology of improving surface defrosting by hydrophobic foil needs to be further studied and the actual production is very few.

The thickness of air conditioner foil is 0.1mm ~ 0.15mm. With the development of technology, there is a trend of further thinning of air conditioning foil, and the leading product thickness in Japan is 0.09mm. In the condition of very thin, the aluminum foil to have good formability, its organization and performance must be uniform, metallurgical defects, less anisotropy is small, at the same time require high strength, good ductility, uniform thickness, straightness is good. Air conditioning of the specifications of the foil and alloy is unitary, suitable for mass production, but its seasonal market is strong, for the professional manufacturers of air conditioning foil, it is difficult to solve the contradictions of peak season in short supply and the off-season almost no demand.

Due to the strong drive the market demand, in recent years, China's air conditioner foil production capacity and technical level enhances unceasingly, already formed medium, including production of air-conditioning foil enterprise group, some large companies such as aluminum, the bohai sea, north China product quality basic has reached the international advanced level. Due to the surplus of domestic production capacity, the market competition is extremely fierce.

(2) cigarette packaging foil.

China is the world's largest cigarette production and consumption power, at present our country has 146 large cigarette factories, an annual output of 34 million large amount of cigarette box, basically using cigarette foil packaging, 30% by spraying foil, 70% use rolling aluminum foil, aluminum foil rolling consumption of 35000 tons, with improvements in people's health consciousness and imported cigarettes, smoke foil demand growth slows significantly, it is expected to a slight increase in recent years. China's cigarette packaging foil accounted for 70% of the total double zero foil, at present there are two or three domestic enterprises can produce high quality smoke foil, technical level and international level, but the overall quality of homebred smoke foil is a certain gap with international level.

(3) decorative foil.

Decorative foil is the decorative material used in the form of aluminum - plastic composite, which makes use of the characteristics of good dyeing properties of aluminum foil and high heat reflectivity. It is mainly used for the decoration of buildings, furniture and some gift boxes. Decorative foil application in construction industry in China began from the 1990 s, from the central cities such as Shanghai, Beijing and guangzhou to spread rapidly across the country, demand has increased dramatically in recent years, the general as building walls and furniture decoration materials, in the appearance of the commercial organizations and are widely used in indoor decoration.

Decorative foil has the advantages of heat insulation, moisture proof, sound insulation, fire protection and easy cleaning, and it is luxurious in appearance, convenient in processing and quick in construction and installation. At present, China's construction and home decoration industry has formed the application of decorative foil. With the rapid development of China's construction industry and the popularization of decorative foil application, the demand for decorative foil will increase greatly. In addition, the use of decorative foil wrapping gifts in foreign countries is very popular, in recent years in China's development speed, expected to have better prospects.

(4) cable foil

The cable foil is made of aluminum foil with the sealing and shielding properties. The aluminum # plastic composite foil is used as the protective cover for the cable. Cable foil requires less oil, no holes, higher mechanical properties, lower overall quality requirements, but extremely strict length requirements.

Domestic advanced cold rolling mill, wan mill and aluminum foil roughing mill can be produced, but the market growth is poor, domestic demand is about 25,000 tons.
