The Development Prospect Of Aluminium Foil Jumbo Roll

The development prospect of aluminium foil jumbo roll

a) Conditioning foil

Air-conditioning foil is a special material for the manufacture of heat exchanger fins for air conditioners. The air-conditioning foil used in the early days was plain foil. In order to improve the surface properties of plain foil, anti-corrosion inorganic coating and hydrophilic organic coating are applied before forming to form hydrophilic foil. 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, which makes the surface of the fins have a water-repellent function to prevent condensed water from sticking. Since the technology of hydrophobic foils to improve surface defrosting needs to be further studied, there is little actual production.

The thickness of the air conditioner foil is 0.1mm to 0.15mm. With the development of technology, there is a trend of further thinning of air-conditioning foil, and the thickness of Japan's leading product is 0.09mm. In an extremely thin state, alumaluminium foil jumbo rollinum foil must have good formability, its structure and properties must be uniform, less metallurgical defects, small anisotropy, high strength, good ductility, uniform thickness, and good flatness. The specifications and alloys of air-conditioning foil are relatively simple, which is suitable for mass production, but its market is seasonal, and it is difficult for professional manufacturers of air-conditioning foil to solve the contradiction between the shortage of supply in peak season and almost no demand in off-season.

Due to the strong market demand, the production capacity and technical level of my country's air-conditioning foils have been continuously improved in recent years, and now a group of large, medium and low-level enterprises producing air-conditioning foils has been formed. Some large enterprises such as North China Aluminum and Bohai Aluminum have basic product quality Has reached the international advanced level. Due to the excess domestic production capacity, the market competition is extremely fierce.

(2) Cigarette packaging foil

my country is the world's largest producer and consumer of cigarettes. At present, there are 146 large cigarette factories in my country, with an annual output of 34 million large boxes of cigarettes, which are basically packed in cigarette foil, of which 30% are sprayed foil and 70% are rolled. The consumption of aluminium foil jumbo roll and rolled aluminium foil jumbo roll is 35,000 tons. With the enhancement of people's health awareness and the impact of imported cigarettes, the growth of demand for cigarette foil has slowed down significantly, and it is expected to increase slightly in recent years. my country's cigarette packaging foil accounts for 70% of the total double-zero foil. At present, there are two or three domestic companies that can produce high-quality cigarette foil, and the technical level is comparable to the international level.

(3) Decorative foil

Decorative foil is a decorative material applied in the form of aluminum-plastic composite, which utilizes the characteristics of good colorability and high light and heat reflectivity of aluminium foil jumbo roll. Mainly used for construction, furniture decoration and part of gift box packaging. The application of decorative foil in my country's construction industry began in the 1990s, and it spread rapidly from Shanghai, Beijing, Guangzhou and other central cities to all parts of the country. In recent years, the demand has increased sharply. , It is also widely used in the facade and interior decoration of commercial institutions.
