Aluminum foil meets the needs of modern production and life in a very broad field. In the electronics industry, aluminum foil is used to make capacitors, heating elements of evaporators, condensers and cable shielding layers; In the electromechanical industry, aluminum foil is the first choice for heat exchanger fins; In the aerospace industry, the insulation and waterproof layers of liquid fuel tanks such as aircraft rotors, missiles, rockets and satellites are inseparable from aluminum foil; In the packaging industry, aluminum foil is an important packaging material for food, medicine, cigarettes and chemicals. In the construction industry, it is widely used in heat insulation and moisture-proof places as decorative materials; In addition, aluminum foil can be found everywhere in the textile, vehicle and shipbuilding industries.
In a sense, the consumption level of aluminum foil has become an important symbol of a country's economic development level. At present, China has become the second largest consumer of aluminum foil after the United States, but the per capita consumption is only 0. 17kg, which is equivalent to110 to 1/20 in developed countries.
No matter from which aspect, there are huge business opportunities in China aluminum foil market.
In the early days of China, aluminum was mainly used in the military, and there was little demand for aluminum foil. After 1980s, aluminum foil developed as a civilian product. After 1995, the market of cable foil, air conditioning foil and cigarette foil entered a period of rapid growth, and the aluminum foil industry in China developed rapidly.
According to relevant statistics, the average proportion of aluminum foil demand in aluminum materials is about 6%. In China, the demand for aluminum foil is basically in step with the aluminum market. In developed countries, aluminum foil accounts for 7.5% ~ 8% of the total aluminum material, which shows that the consumption level of aluminum foil in China is low as a whole. At present, the most demanding products in China aluminum foil market are air conditioning foil, cigarette foil, decorative foil and cable foil.
The demand of these four varieties accounts for more than 70% of the total demand, while the demand of automobile foil, flexible packaging foil, medical foil and electronic foil is not great, but the market grows well and becomes an important growth point of aluminum foil market.
Market analysis of main products
Air conditioning film is difficult to solve the contradiction between supply and demand. The air-conditioning industry is the largest aluminum foil user at present. Air conditioning foil is a special material for making fins of air conditioning heat exchanger, and the air conditioning foil used in the early days is plain foil. In order to improve the surface properties of ordinary aluminum foil, anticorrosive inorganic coating and hydrophilic organic coating were coated before molding to form hydrophilic aluminum foil. At present, hydrophilic foil accounts for the total amount of air conditioning foil.
50%, the proportion of its use will be further improved. In addition, there is hydrophobic foil, which makes the surface of fin have hydrophobic function and prevents condensate from sticking. Because the technology of improving the surface defrosting of hydrophobic foil needs further study, there is little actual production at present.
The thickness of air conditioning foil is 0.1mm ~ 0.15 mm. With the development of technology, air-conditioning foil tends to be thinner. Now the leading product in Japan is 0.09 mm thick. In an extremely thin state, aluminum foil should have good formability, uniform structure and properties, few metallurgical defects and small anisotropy, and at the same time, it requires high strength, good ductility, uniform thickness and good flatness. The specification and alloy of air conditioning foil are relatively simple, which is suitable for mass production. However, its market is seasonal, and it is difficult for professional manufacturers of air-conditioning foil to solve the contradiction that demand exceeds supply in peak season and there is almost no demand in off-season.
Driven by strong market demand, the production capacity and technical level of air-conditioning foil in China have been continuously improved in recent years. At present, large, medium, small, high and low-grade enterprise groups have been formed, and the product quality of some large enterprises such as Huabei Aluminum and Bohai Aluminum has basically reached the international advanced level. Due to domestic overcapacity, the market competition is extremely fierce.
The demand for cigarette packaging foil slowed down obviously. China is the largest producer and consumer of cigarettes in the world. At present, there are 146 large cigarette factories in China, with an annual output of 34 million cartons of cigarettes, all of which are basically packed with cigarette foil, of which 30% are sprayed foil and 70% are rolled aluminum foil, with an annual consumption of 35,000 tons of rolled aluminum foil. With the enhancement of people's health awareness and the impact of imported cigarettes, the demand for cigarette foil has obviously slowed down and is expected to increase slightly in recent years. China cigarette packaging foil accounts for the total amount of double zero foil.
At present, there are two or three domestic enterprises that can produce high-quality cigarette foil, and their technical level is equivalent to the international level, but the overall quality of domestic cigarette foil is somewhat different from the international level. Due to the shortage of high-quality cigarette foil in China, some of them rely on imports.
The demand for decorative foil will increase greatly. Decorative foil is a kind of decorative material applied in the form of aluminum-plastic composite, which makes use of the characteristics of good coloring and high photothermal reflectivity of aluminum foil. Mainly used for decoration of buildings and furniture and packaging of some gift boxes. The application of decorative foil in China's construction industry began in the 20th century.
Since the 1990s, it has spread rapidly from Shanghai, Beijing, Guangzhou and other central cities to all parts of the country. In recent years, the demand has increased dramatically. Generally used as decorative materials for interior walls and indoor furniture of buildings, and also widely used for facade and indoor decoration of commercial institutions.
Decorative foil has the advantages of heat insulation, moisture resistance, sound insulation, fire prevention, easy cleaning, luxurious appearance, convenient processing and quick construction and installation. At present, the application upsurge of decorative foil in China's construction and home improvement industry has been formed. With the rapid development of China's construction industry and the continuous popularization of decorative foil application, the demand for decorative foil will increase greatly. In addition, the use of decorative foil packaging gifts is very popular abroad, and it has developed rapidly in China in recent years, and it is expected to have a better prospect.
The cable foil with poor market growth is an aluminum-plastic composite foil with aluminum foil as raw material and plastic film coated on one or both sides for cable shielding. Cable foil requires less oil on the surface, no holes, high mechanical properties and low overall quality, but its length is extremely strict. At present, domestic advanced cold rolling mills, universal rolling mills and aluminum foil roughing mills can all be produced, but the market growth is poor, and the domestic annual demand is 25,000 tons.
Aluminum foil products with rapidly growing demand
The market demand of composite foil for automobile is growing rapidly. With the vigorous development of China's automobile industry and the continuous improvement of automobile aluminization rate, the market demand for aluminum foil for automobile is increasing rapidly. There are two kinds of foil for automobile: one is composite foil for automobile air conditioning, which has been fully aluminized in China, and the annual demand for aluminum foil is 6.5438+0.5 million tons; The other is composite foil for automobile radiator, which is used to manufacture automobile water tank radiator, automobile condenser and evaporator. At present, the aluminization rate of automobile water tank reaches 40%, and the annual demand is about 3000 tons.
The application proportion of medicine foil is increasing. Medical packaging aluminum foil mainly includes aqueous solution, easy-to-open bottle cap for injection and PTP aluminum foil for medicine. PTP aluminum foil is widely used in international pharmaceutical industry because of its advantages of moisture-proof, portability, safety and hygiene. Starting from 1985, China began to use aluminum foil to package drugs. Up to now, aluminum foil only accounts for 20% of pharmaceutical packaging materials. In recent years, the pharmaceutical aluminum foil market has developed rapidly. On the one hand, the pharmaceutical market has developed rapidly, but mainly because the proportion of PTP aluminum foil used in pharmaceutical packaging has been increasing.
Flexible packaging aluminum foil has great development space. Flexible packaging is a bag-like container made of soft composite packaging materials. The emergence of soft packaging has greatly improved the mechanization and automation level of food and beverage industry, and accelerated the modernization and socialization process of people's diet life. In developed countries, soft packaging has become one of the main packaging forms of food and beverage, replacing canned and bottled in a certain range. In recent years, the flexible packaging market in China has also developed rapidly. Up to now, aluminum foil composite production line 10 has been introduced. According to the different uses of flexible packaging, different processes such as dry composite, hot melt composite and extrusion composite can be adopted. Flexible packaging not only has the functions of moisture-proof and fresh-keeping, but also can print various patterns and characters, and is an ideal material for modern commercial packaging. With the improvement of people's living standards, there is still a lot of room for development of flexible packaging aluminum foil.
There is little demand for aluminum foil for electrolytic capacitors. Aluminum foil for electrolytic capacitors is a corrosive material working under polar conditions, which requires high structure of aluminum foil. There are three kinds of aluminum foils used: cathode foil with a thickness of 0.015 mm ~ 0.06 mm; High-voltage foil, thickness 0.065 mm ~ 0. 1 mm, made of high-purity aluminum; Low-voltage foil with a thickness of 0.06 mm ~ 0.1mm.
There are few domestic manufacturers of electrolytic capacitor aluminum foil, mainly because the market demand is not great and the production technology is far from that of advanced countries. Aluminum electrolytic capacitor has good performance, low price and wide application, so it has a good market prospect. At present, the annual demand in Japan is
45,000 tons, six times that of the China market. With the development of electronic industry and China becoming the main industrial production base, the market demand of electrolytic capacitor aluminum foil has a broad prospect.
Xinxing aluminum foil products
Aluminum foil for composite hose has excellent properties. The composite hose is mainly used for packaging paste and semi-exposed products, and can be used as a container for toothpaste, ointment and some chemical cleaning products. It has the advantages of good insulation, not easy to be broken, clean and beautiful. If used as toothpaste packaging, it is a promising material. In Europe, America, Japan and other developed countries, more than 90% of toothpaste is packaged in this way. The consumption of toothpaste in China is 9 billion pieces/year, but at present only 3.5% of toothpaste is packed with composite hoses. The important reason is the limited production capacity and high production cost of composite materials. Some toothpaste manufacturers do not have supporting hose packaging production lines. Composite hose packaging can save medicine and a lot of aluminum, and has excellent performance and good development prospects.
Household aluminum foil will be widely used in food cooking, which can be directly steamed on the fire, so that the food is heated evenly inside and outside, and the original flavor and beautiful luster of the food are maintained. Therefore, aluminum foil, as a high-temperature resistant cooking material or packaging material, is applied to families, restaurants and food stores, which is in great demand in developed countries and has a good market prospect. The demand for household aluminum foil in Japan has exceeded 10% of the total aluminum foil.
At present, domestic restaurants and food stores mostly use household aluminum foil. With the improvement of people's living standards, the application of household aluminum foil in China will continue to spread, with great market potential.
Competition analysis between aluminum foil and substitutes
The main uses of aluminum foil can be divided into two categories: one is as a consumer material such as packaging or decoration. At present, this kind of aluminum foil accounts for 60% of the total demand in China market, and reaches more than 80% in developed countries such as the United States and Japan. The other is the auxiliary raw materials used in industrial production. The first kind of products mainly use the characteristics of aluminum foil, such as good sealing, good coating and beautiful appearance, and its substitutes are plastic and paper. The second kind of products mainly use the special physical and chemical properties of aluminum foil, and its substitute is special metal or metal alloy foil. Because aluminum foil has two advantages of easy processing and low cost, it is difficult for other foil materials to replace aluminum foil in industrial production. Therefore, only the first type of aluminum foil products face the competition of substitutes.
Aluminum foil packaging, plastic packaging and paper packaging are the three main forms of flexible packaging at present. Plastic and paper for packaging have the advantages of low price and portability, and these two packaging materials greatly restrain the market demand for packaging aluminum foil. The general plastic packaging and paper packaging are easy to be damaged, with poor safety, and the quality assurance and sealing effect are far less than that of aluminum foil packaging. The development of aluminum-plastic composite technology and aluminum foil lining paper technology has greatly stimulated the market demand of packaging aluminum foil. Aluminum foil and substitutes are both competitive and cooperative. At present, aluminum-plastic composite production technology and production cost are important factors restricting the development of packaging foil berths. The paper-plastic production process is polluted and the product recovery rate is low. With the improvement of social environmental protection requirements, its application scope will be limited. However, due to the continuous thinning of aluminum foil, the production cost is continuously reduced and the application range is rapid.
The trend of growth.
Another competitive product of aluminum foil is sprayed aluminum foil, which is used for packaging daily necessities such as cigarettes, but the consumption is decreasing at present.
