Application prospect of aluminum foil in food pack

  • Detail

Discussion on the application prospect of aluminum foil in food packaging industry with the improvement of China's comprehensive national strength and the huge increase of foreign trade volume, China's packaging industry is rising rapidly, and various new packaging materials are emerging in endlessly. In particular, the application of aluminum foil in the packaging industry has increasingly shown its unique superior performance, forming a new market growth point and opening up new incremental space for the consumption of aluminum foil in the packaging industry

aluminum foil has the characteristics of light material, high barrier, shading, UV resistance, moisture resistance, corrosion resistance, heat insulation, long shelf life, sanitation, etc., and has the advantages of easy folding, excellent adhesion and heat sealing, excellent surface printing performance and decorative effect in deep processing and utilization. As an excellent packaging material, aluminum foil is widely used in cigarette, food, candy, dairy products, beverages, medicine, machinery, electronics, photographic equipment, daily chemical industry and other industries. With the rapid development of global packaging industry, packaging industry has become an important pillar industry in developed countries

in the United States, the packaging industry has become the third largest industry; In Europe, the packaging industry is the seventh largest industry. The development of the global packaging industry has greatly boosted the consumption of aluminum foil, making the packaging industry the largest application and consumption market of aluminum foil. According to the statistics of European aluminum foil industry association, more than 70% of aluminum foil in Europe is used in various packaging products. In the United States, the ratio is as high as 75%, and in Japan, the consumption of aluminum foil for packaging accounts for 70%, of which food packaging alone accounts for 30% of the consumption of aluminum foil

at present, there are more than 10000 packaging enterprises in China, with an annual output value of 328.3 billion yuan. Among the 42 major industries in the country, the packaging industry has risen from the penultimate in the early 1980s to the 14th now. In the global packaging consumption market of about 600billion US dollars, China has become the third largest packaging country after the United States and Japan. In recent years, with the rapid development of China's packaging industry, the application of aluminum foil in the packaging field has also increased rapidly. At present, China's consumption of aluminum foil for packaging is about 110000 tons/year, including about 38000 tons of aluminum foil for cigarette packaging, accounting for 34.5% (Note: China has signed the International Framework Convention on tobacco control in November 2003, and before November 10, 2006, domestic tobacco enterprises will switch to environmental friendly vacuum aluminized paper, which will sharply reduce the consumption of aluminum foil for cigarettes); About 20000 tons of aluminum foil for food packaging, accounting for 18.2%; About 9000 tons of aluminum foil for dairy products packaging, accounting for 8.2%; About 5000 tons of aluminum foil for daily chemical packaging, accounting for 4.5%; Other packaging aluminum foil is about 10000 tons, accounting for 9.1%. In 2005, the consumption of aluminum foil in China was about 600000 tons, and the proportion of aluminum foil for packaging was 18.3%. It can be seen from the above that there is still a big gap between the application ratio of aluminum foil in packaging industry in China and that in developed countries

flexible packaging: flexible packaging is a new type of packaging developed in recent years. It has the special effects of moisture-proof and fresh-keeping. It is a very ideal packaging product for modern packaging. It is a bag type packaging container (such as cooking bag and standing bag) made of aluminum foil, plastic and other materials. As far as the cooking bag is concerned, it has air tightness, shading and heat resistance. If the food is packaged in the cooking bag, its shelf life can be extended to 2 years, and it can withstand the high-temperature sterilization treatment of 120 ℃ ~150 ℃. It is widely used in the packaging of sauce, paste food and space food. In developed countries, flexible packaging has become the main form of food and beverage packaging, especially in Europe, the United States and Japan. At present, flexible packaging has become the mainstream of global food packaging. In 2005, the global output value of flexible packaging reached US $65.8 billion, with an average growth rate of more than 5%. It has become one of the top ten packaging technologies that can most affect the packaging industry in the world in recent years. In recent years, China's flexible packaging market has developed rapidly, with an annual growth rate of 9.5%, second only to India's 12% growth rate. With the rise and rapid development of flexible packaging in China, the annual consumption of aluminum foil is more than 20000 tons, and there will be more room for market increment in the future

aluminum plastic composite packaging: in modern packaging, almost all products requiring opaque or high barrier composite materials use aluminum foil as the barrier layer of packaging products. Aluminum plastic composite packaging is the most widely used and used product. Among the aluminum-plastic packaging materials, the following aluminum-plastic composite packaging has a promising future

aluminum plastic composite can material is composed of aluminum foil, plastic film and kraft board. It is processed into various shapes of packaging cans. It is non-toxic, tasteless and pollution-free, and can be recycled. It is a substitute for tinplate cans, cooking cans and other liquid packaging containers widely used in the market. It is especially suitable for the packaging of frozen food and flat food and for containing engine oil. The two kinds of bio based epoxy obtained in the market have reached UL ⑼ 4 V0 industrial flame retardant level, with considerable amount Aluminum plastic composite film is composed of aluminum foil and high-strength and heat sealable plastic film. It has barrier, mechanical and heat sealing properties. It is an excellent aluminum plastic composite flexible packaging material with great application potential, and is widely used in the packaging of food, chemicals and military products

in fact, the gap with developed countries is not very large. The aluminum-plastic composite hose is compounded with aluminum foil and plastic or resin, and then processed into tubular semi-rigid packaging products by pipe making equipment. It is mainly used for the packaging of paste and dew products, such as the packaging containers of toothpaste, ointment, cosmetics and other daily-use chemical products. Aluminum plastic composite hose has the advantages of good isolation, not easy to crack, clean and beautiful. In developed countries such as Europe, the United States and Japan, more than 90% of toothpastes are packed with aluminum-plastic composite hoses, while the rate of such packaging in China is less than 5%. The annual consumption of aluminum foil for aluminum-plastic composite hose in China is about 5000 tons. With the development of this emerging market, the consumption of aluminum foil in this field will develop rapidly

wine sealed packaging: Wine sealed packaging is a new type of packaging material produced with the requirements of beer hygiene standards in recent years. Aluminum foil is widely used in bottle neck and bottle mouth sealing packaging of beer, fruit wine and high-grade soy sauce because of its good ductility, tensile strength and easy printing. The utility model can prevent dust from entering around the bottle cap, which brings unsanitary food, and has a beautiful and elegant packaging effect. In recent years, with the change of Chinese food consumption habits, beer consumption has increased greatly. In 2005, the national beer output was 30.62 million tons, ranking the first in the world for many consecutive years. Its packaging aluminum foil also increased rapidly, reaching an annual consumption of more than 10000 tons of aluminum foil, and there is still a large incremental space

pet food packaging: pet food has some special requirements on packaging, which can be re sealed after opening, and must have the characteristics of heating, preservation, corrosion prevention and moisture resistance. In meeting these requirements, aluminum foil has become the first choice of pet food packaging materials. In addition, according to foreign statistics, about 70% of the recovery rate of packaging products can be achieved. In recent years, pet food packaging products made of aluminum foil have developed rapidly in the European and American markets. At present, it is still a blank market to be developed in China, and its application and consumption potential are great. In addition, with the development of new packaging technology, selective aluminum foil packaging, anti freezing aluminum foil packaging, anti condensation aluminum foil packaging, aseptic packaging, Tetra Pak and other new packaging methods will open a series of new incremental market space for the application of aluminum foil in the packaging field

from the perspective of the development prospect of China's packaging industry, the state has put forward the development plan of agricultural industrialization in the field of food, and food processing has been listed as a key priority development area. It is expected that the output value of food packaging will increase by more than 12% every year in the future. Dairy and beverage industry has become the most growing industry, and various kinds of flexible packaging products have appeared in the market. At present, the annual output value of China's pharmaceutical packaging industry is 15billion yuan, which can only meet 80% of the packaging needs of domestic pharmaceutical enterprises. It is expected that the pharmaceutical packaging industry will achieve rapid development during the Eleventh Five Year Plan period. In the daily chemical industry, daily chemical products are entering a market boom period with great development potential. In the packaging industry, it is one of the most updated and fastest growing markets. It can be seen that the future growth space of China's aluminum foil demand is mainly to support a large capacity market with aluminum foil for packaging until it passes the inspection. Industry experts predict that by the end of the 11th Five Year Plan period, China's annual demand for packaging aluminum foil will reach about 250000 tons, which will be 1.3 times the current consumption of packaging aluminum foil. In the next few years, the growth rate of aluminum foil for packaging will greatly exceed that of the three major applications of aluminum foil for air conditioning, decoration and cables in China

more than 90% of aluminum foil used for packaging is double zero aluminum foil. At present, there are 7 large-scale enterprises producing double zero aluminum foil in China. In 2005, the national output of double zero aluminum foil was about 115000 tons, of which xiashun aluminum foil, Huabei aluminum and Danyang aluminum accounted for a large market share. In recent three years, the domestic aluminum sheet, strip and foil processing industry has achieved rapid development. Before 2008, five new enterprises represented by Nanshan and Wanji will give full play to the capacity advantage of 20 2000mm wide aluminum foil mills and join the double zero aluminum foil manufacturing camp. It provides a strong aluminum foil material guarantee for the rapid development of China's packaging industry
