(a) 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 accounts for 70% of the total amount of double zero foil, at present, there are two or three domestic enterprises can produce high-quality cigarette foil, the technical level is equivalent to the international level, but the overall quality of domestic cigarette foil has a certain gap with the international level.
(two) air conditioning foil
The thickness of air conditioning foil is 0.1mm ~ 0.15mm. With the development of technology, air conditioning foil has a tendency of further thinning. The thickness of leading products in Japan is 0.09mm now. In the very thin state, aluminum foil to have good formability, its structure and performance must be uniform, metallurgical defects less, small anisotropy, and requires high strength, good ductility, uniform thickness, good flatness. The specifications and alloy of air conditioning foil are relatively single, which is suitable for large-scale production. However, the market is seasonal. For professional manufacturers of air conditioning foil, it is difficult for them to solve the contradiction between short supply in peak season and almost no demand in off-season.
Air conditioning foil is a special material for the manufacture of heat exchanger fins for air conditioners. The early air conditioning foil used is a plain foil. In order to improve the surface performance of plain foil, anticorrosive inorganic coating and hydrophilic organic coating were applied before forming to form hydrophilic foil. At present, hydrophilic foil accounts for 50% of the total amount of air conditioning foil, and its use proportion will be further increased. In addition, there is a hydrophobic foil, so that the fin surface has the function of hydrophobic, prevent condensation water adhesion. Because the technology of hydrophobic foils to improve the surface defrost needs further research, the actual production is very few at present.
Drived by the strong market demand, the production capacity and technical level of air conditioning foil in China have been continuously improved in recent years, and now there are large, medium, medium and low size enterprises producing air conditioning foil. The product quality of some large enterprises, such as North China Aluminum and Bohai Aluminum, has basically reached the international advanced level. Due to excess domestic production capacity, the market competition is extremely fierce.
(3) decorative foil
Decorative foil is a decorative material applied in the form of aluminum - plastic composite, which takes advantage of the characteristics of good coloring and high photothermal reflectivity of aluminum foil. Packaging belt manufacturers are mainly used for construction, furniture decoration and part of the gift box packaging. The application of decorative foil in China's construction industry began in the 1990s, spreading rapidly from Shanghai, Beijing, Guangzhou and other central cities to all over the country. In recent years, the demand has increased sharply. It is generally used as decorative materials for the inner wall of buildings and indoor furniture, and is also widely used in the facade and interior decoration of commercial institutions.
Decorative foil has the advantages of heat insulation, moisture-proof, sound insulation, fire protection and easy cleaning, and the appearance of luxury, convenient processing, construction and installation speed. At present, China's construction, home decoration industry has formed a decorative foil application boom. With the rapid development of China's construction industry and the continuous popularity of decorative foil applications, the demand for PP packing belt decorative foil will increase greatly. In addition, the use of decorative foil packaging gifts are very popular abroad.
