Packaging aluminum foil key product introduction

(1) Air conditioning foil

Air conditioning foil is a special material for the manufacture of heat exchanger fins for air conditioners, and the air conditioning foil used in the early days is plain foil. In order to improve the surface properties of the plain foil, the hydrophilic foil is formed by applying the antiseptic inorganic coating and the hydrophilic organic coating before forming. Hydrophilic foil accounts for 50% of the total air conditioning foil, and its use ratio will be further increased. In addition, there is a water-repellent foil, so that the surface of the fin has a water-repellent function to prevent condensation from sticking. Because the technology of hydrophobic foil to improve the surface defrosting property needs further research, the actual production is few.

The thickness of air conditioner foil is 0.1mm ~ 0.15mm. With the development of technology, the air conditioning foil has a further thinning trend, and the leading product thickness in Japan is 0.09mm. In the extremely thin state, the packaging aluminum foil to have good formability, its organization and performance must be uniform, fewer metallurgical defects, small anisotropy, while requiring high strength, good ductility, uniform thickness, flatness. The specifications and alloys of air conditioning foil are relatively single, suitable for large-scale production, but its market seasonality is strong, and it is difficult for professional manufacturers of air conditioning foil to solve the contradiction between short supply in the peak season and almost no demand in the off-season.

Due to the strong market demand, China's air conditioning foil production capacity and technical level continues to improve, has formed large, medium, high and low production of air conditioning foil enterprise groups, some large enterprises such as North China Aluminum, Bohai aluminum product quality has basically reached the international advanced level. Due to the excess of domestic production capacity, the market competition is extremely fierce.

(2) Cigarette packaging foil

China is the world's largest cigarette production and consumption country, China has 146 large cigarette factories, with an annual output of 34 million large boxes of cigarettes, basically using cigarette foil packaging, of which 30% using spray foil, 70% using rolled aluminum foil, rolled aluminum foil consumption of 35,000 tons, with the increase of people's health awareness and the impact of imported cigarettes, The growth of cigarette foil demand has slowed significantly and is expected to increase slightly. China's cigarette packaging foil accounts for 70% of the total number of double zero foil, 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 and the international level has a certain gap.

(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. Mainly used for construction, furniture decoration and part of the gift box packaging. The application of decorative foil in China's construction industry is from the beginning of the 1990s, from Shanghai, Beijing, Guangzhou and other central cities to the rapid spread across the country, the demand has increased sharply, generally as the interior wall of the building and interior furniture decoration materials, in the facade of commercial institutions and interior decoration is also widely used.

Decorative foil has the advantages of heat insulation, moisture proof, sound insulation, fire prevention and easy cleaning, and luxurious appearance, convenient processing, construction and installation speed. China's construction and home improvement industry has formed a boom in the application of decorative foil. With the rapid development of China's construction industry and the continuous popularization of decorative foil application, the demand for decorative foil will also have a substantial increase. In addition, the use of decorative foil packaging gifts is very popular in foreign countries, the development speed in our country is very fast, is expected to have a better prospect
