Aluminum Foil Has Been Widely Used
Sep 01, 2017

Aluminum foil classification by use of large categories can be divided into packaging foil, Aluminum Foil daily necessities foil, electrical equipment foil and construction foil.

The use of aluminum foil is very wide, such as aviation food packaging, general meat packaging, cable foil, building insulation materials and so on. In developed countries in Europe and the United States, the packaging of aluminum foil products accounted for 70% of the total demand. Today, aluminum foil in the Chinese market has developed rapidly, people in daily life more and more can see the figure of aluminum foil. So what is aluminum foil?

Aluminum foil is the use of 99%-99.7% pure electrolytic aluminum, after many times calendering, this soft metal film, not only moistureproof, airtight, shading, but also has the advantages of incense, non-toxic tasteless, such as the advantages of the existing other packaging materials can not be compared. This is the practical side of aluminum foil, its gorgeous side is embodied in its elegant silver-white luster, Aluminum Foil people can give full play to the imagination, printed on the above features, colorful beautiful patterns and patterns.

It is because of the super practical and colorful, aluminum foil packaging is increasingly favored by people, the market space Unlimited.

Advantages of aluminum Foil: aluminum foil with shiny metal luster, decorative strong; non-toxic, tasteless, odorless, relatively light weight, the proportion is only iron, copper, etc. one-third, rich extensibility, thin thickness, the unit area of small weight; good shading, reflective rate of up to 95%; strong protection, so that the packaging is not susceptible to bacteria, fungi and insects ; Aluminum Foil High temperature and low temperature stability, temperature in-73~371℃ shrinkage deformation; barrier is very good, moisture-proof, airtight, fragrant, can prevent the packaging content of moisture absorption, oxidation and volatilization, Aluminum Foil its moisture resistance, oxygen resistance. Aluminum foil is easy to process, can be combined with a variety of plastic film and paper.

The four uses of aluminum foil are:

Air conditioner Foil

Air conditioner foil is the special data of heat exchanger fin for air conditioner, and the early use of air conditioner foil is the foil. In order to improve the appearance of the foil performance, before the formation of anti-corrosion inorganic coating and hydrophilic organic coating, forming hydrophilic foil. Aluminum Foil The current hydrophilic foil account for the total amount of air conditioner in the%1, its utilization ratio will further progress. There is also a kind of hydrophobic foil, so that fin surface has a hydrophobic function, to avoid condensation water adhesion. Because the hydrophobic foil to improve the appearance of defrosting skills to be further discussed, Aluminum Foil the current practice produces little.

The air conditioner foil thickness is 0.1mm~0.15mm. With the development of skills, air conditioning foil to further reduce the trend, Japan today's leading product thickness of 0.09mm. In the extremely thin state, the aluminum foil must have the good formability, its arrangement and the performance is necessary even, the metallurgical flaw is few, each anisotropy is small, together needs the intensity high, Aluminum Foil the ductility is good, the thickness is homogeneous, the flatness is good. Air conditioning foil standard and alloy relatively single, suitable for large-scale production, but its seasonal strong, about air conditioning foil professional manufacturers, it is difficult to deal with the peak season demand and cold season almost no need contradiction.

Because of the weak stock market needs, in recent years, China's air conditioning foil production capacity and technical level of continuous progress, has been formed in large and medium-sized, Aluminum Foil high school low production air-conditioning foil company groups, some large companies such as North China aluminum, Bohai Aluminum product quality has reached the world leading level. Aluminum Foil Because the domestic production capacity is excessive, the market competition is unusually fierce.

II. Cigarette packaging foil

China is the world's largest production and cost of cigarettes, the current China has 146 large-scale cigarette factory, annual output of 34 million large boxes, Aluminum Foil the basic choice of cigarette foil packaging, in which 30% selected spray foil, 70% selected calendering aluminum foil, Calendering aluminum foil consumption of 35,000 tons, along with the increase in citizen health awareness and foreign import cigarette impact, smoke foil need to add a significant slowdown, estimated in recent years will be slightly added. Chinese cigarette packaging foil accounted for 0 foil total of 70%, the current domestic two or three companies can produce high-quality tobacco foil, Aluminum Foil skill level and world-level appropriate, but the overall quality of domestic tobacco foil and the world standard has a certain distance.

III. Decoration Foil

Decoration foil is an aluminum-plastic composite of the use of the decoration materials, the use of aluminum foil color good, high reflectivity of light and heat characteristics. First used for construction, furniture decoration and a part of gift box packaging. Decoration foil in China's construction industry in the use of the beginning of the the 1990s, from Shanghai, Beijing, Guangzhou and other central cities to the rapid extension of the country, Aluminum Foil in recent years need to increase the volume, usually as a building interior wall and interior furniture decoration information, in the commercial organization of the façade and interior decoration is also widely used

Decoration foil with heat insulation, moisture, noise, fire and easy to clean and other advantages, and the appearance of luxury, processing facilities, construction equipment speed. Currently China's construction, decoration industry has formed the use of decorative foil craze. With the rapid development of China's construction industry and the continuous popularization of decoration foil, the need for decoration foil will have a large amount of added. Other, the selection of decoration foil packaging gifts in foreign countries very popular, in recent years in China's rapid development, it is expected to have a better vision.

IV. Cable FOIL

Cable foil is the use of aluminum foil airtight and shielding, single-sided or double-sided coating on the plastic film, composed of aluminum # plastic composite foil, used as a cable shield. The cable foil needs the outward appearance to carry the oil quantity little, has no hole, has the high mechanical performance, the overall quality need is not high, but to the length need extremely stern.

At present, the domestic leading cold rolling mills, universal mill and aluminum foil roughing mill can be produced, but the growth of the mall is poor, the domestic needs of 25,000 tons per year.

Aluminum foil According to the surface state can be divided into one light aluminum foil and two light aluminum foil. ① one side of the light aluminum foil: Double rolled aluminum foil, after the volume of light,-surface hair, such as aluminum foil is called a light aluminum foil. Aluminum Foil The thickness of a light foil usually does not exceed O. 025mm. ② Two-sided light aluminum foil: Single sheet rolling aluminum foil, both painting and roll contact, aluminum foil on both sides of the surface roughness of the rollers are divided into mirror two surface light aluminum foil and ordinary two-sided light aluminum foil. Two surface light aluminum foil thickness is generally not less than 0. 01mm.

Aluminum foil According to the state can be divided into the element foil, embossed foil, composite foil, coated foil, color aluminum foil and printed aluminum foil. ① foil: After rolling, no other processing of aluminum foil, also known as light foil. ② Embossed Foil: The surface is embossed with various patterns of aluminum foil. ③ Composite Foil: The aluminum foil and paper, plastic film, cardboard laminating in-formed composite aluminum foil. ④ coated Foil: The surface is coated with various types of resin or lacquer foil. ⑤ Colored aluminum Foil: the surface is coated with a single color of aluminum foil. ⑥ Printing aluminum Foil: by printing on the surface to form a variety of patterns, patterns, text or picture of the aluminum foil, can be a color, up to 12 kinds of color.

Aluminum foil with light weight, airtight and cladding of good and so on-series of advantages, therefore, in many sectors of the national economy and People's daily life to obtain a wide range of applications, but at present it is mainly used in packaging, electromechanical and construction of the three major areas.
