Air conditioning aluminum foil

Air conditioning foil is a film material that can protect air conditioning units. It prevents dust, dirt, and other debris from entering the interior of the air-conditioner, keeping it clean and in good working condition. Air conditioning foil can also act as a heat insulator, preventing the air conditioning unit from emitting too much heat to the outside, improving the efficiency and energy saving of the air conditioner. Using air conditioning foils can extend the service life of air conditioning units and reduce the cost of repairs and maintenance. Different sizes of air-conditioning foils can be selected according to the model and size of the air-conditioning unit to ensure complete coverage and protection of every part of the air-conditioning unit. Convenient and easy to install and remove, air conditioning foils protect air conditioning units in every home and office environment.

Air conditioning foil is a material specifically used to make fins for heat exchangers. Early air conditioning foils used were plain, but hydrophilic foils were developed to improve their surface properties. Hydrophilic foils, coated with corrosion-resistant inorganic coatings and hydrophilic organic coatings before forming, account for 50 percent of the total air conditioning foils and are used in progressively higher proportions. In addition, there is a hydrophobic foil that has the function of preventing condensate from adhering. Still, since the technology for improving the defrosting properties of surfaces with hydrophobic foils requires further research, actual production is low.
The thickness of air-conditioning foils ranges from 0.1mm to 0.15mm. As technology continues to evolve, air-conditioning foils are being developed toward even greater thinness, with Japan’s main product already reaching a thickness of 0.09mm. In a very thin state, aluminum foil needs to have good formability, its organization, and properties must be uniform, with fewer metallurgical defects and less anisotropy, and it also requires high strength, flexibility, uniform thickness, and good flatness. Air-conditioning foils are suitable for mass production because of their relatively small number of specifications and alloy types. However, due to the strong seasonality of the market, it is difficult for specialized manufacturers of air-conditioning foils to solve the contradiction between the oversupply in the peak season and the virtually non-demand in the off-season.

In recent years, due to market demand growth, the production capacity and technical level of air-conditioning foils in China have been significantly improved. Now, China has formed a group of enterprises producing large, medium, small, high, medium, and low-end air-conditioning foils, and some of these large enterprises, such as North China Aluminium and Bohai Aluminium, have reached the internationally advanced level of product quality. However, due to the excess production capacity in China, the market competition has become extremely fierce.

Aluminum Foil for Cigarette Packaging 

Cigarette packaging foil is a film material used for packaging cigarettes. It is usually made from a composite of aluminum foil and paper and has the property of blocking light, gas, and moisture. The main function of cigarette packaging foil is to protect tobacco from the external environment and ensure the quality and taste of tobacco. In addition, cigarette packaging foil also serves as an anti-counterfeiting, decorative, and display product. It can be personalized through printing, hot stamping, and coating processes to improve brand recognition and market competitiveness. Cigarette packaging foil is an indispensable and important material in the cigarette industry, playing a decisive role in the quality and appearance of cigarette products.

China is the world’s largest cigarette-producing and consuming country. There are 146 large cigarette factories in China, with an annual output of 34 million large boxes. These cigarettes are packaged in cigarette foil, of which 30% is spray-plated, and 70% is calendered aluminum foil. The consumption of calendered aluminum foil reaches 35,000 tonnes. With increased health concerns and the impact of foreign cigarette imports, the demand for cigarette foil has slowed significantly but is expected to increase slightly in recent years.

It accounts for 70 percent of the total cigarette packaging foil in China. There are two or three domestic enterprises capable of producing high-quality cigarette foil, with a technical level comparable to the international level.

Aluminum Foil for Decoration

Decorative foil for aluminum-plastic composite is a decorative material that uses the characteristics of good coloring and high light and heat reflectivity of aluminum foil. It is mainly used for decorating buildings and furniture, as well as packaging some gift boxes. In China’s construction industry, decorative foil was applied in the 1990s. It was initially limited to major cities such as Shanghai, Beijing, and Guangzhou but has now spread rapidly throughout the country. In recent years, market demand has increased dramatically, and decorative foils are commonly used as decorative materials for the interior walls of buildings and furniture. They are widely used in the facades and interiors of commercial organizations.

Decorative foil has the advantages of heat insulation, moisture resistance, sound insulation, fire prevention, easy cleaning, luxurious appearance, convenient processing, and fast construction. China’s construction and home decoration industries have seen a boom in the application of decorative foils. With the rapid development of China’s construction industry and the continuous promotion of the application of decorative foils, the demand for decorative foils will increase significantly. In addition, the use of decorative foils as a gift-wrapping method, which has long been popular abroad, has also developed rapidly in China in recent years and is expected to have a good future.

Aluminum Foil for Cable

Cable foil is a metal foil material used for cable insulation. It is usually made of aluminum or aluminum alloy and has good conductivity and corrosion resistance. Cable foil is widely used in electric power, communication, and other fields to protect the cable insulation layer. Due to the unique properties of cable foil, it can effectively improve the performance and service life of cables.

Cable foil is a composite material used for cable protection, mainly composed of aluminum and plastic film. Based on aluminum foil’s airtight and shielding properties, an aluminum-plastic composite foil is formed by applying a plastic film on one or both sides. The surface of the cable foil needs to contain a small amount of oil, be free of holes, and have high mechanical properties. Although the quality requirements are low, the length requirements are extremely strict.
The country has the production capacity of advanced cold rolling mills, 10,000 mills, and aluminum foil roughing mills. Still, the market development prospects could be better, and the annual domestic demand is only about 25,000 tonnes.
