The pop industry in China started in 80’s, when annual output of only 2.4 billion. In recent years, the rapid development of China’s canning industry, cans of demand is also increasing year by year. Currently, the annual domestic consumption of cans in the 8 billion or so.
Still the main market of aluminum cans
Aluminum cans first appeared in the late 20th century, 50, development is very fast, and beverage containers occupy a large proportion. With the beer and beverage manufacturing industry to improve the overall level of world consumption of aluminum cans is growing year by year. End of this century, annual global consumption of aluminum cans has reached 180 billion, the current annual demand at 210 billion, accounting for about half of global output of more than metal containers.
China’s per capita consumption of aluminum cans is still very low, average only 80 cans / person, while the U.S. has more than 400 cans / person. Therefore, the development of China’s aluminum cans is a huge potential market.
With the rising international price of aluminum, aluminum cans manufacturers make life increasingly difficult, in my 25 aluminum can manufacturing enterprises in three have closed down. Countries have introduced corresponding policy, it becomes clear that approval of the new production line of aluminum cans. In this context, emerged cans steel cans and paper, aluminum cans into the alternative products.
Obvious advantages of steel cans
Steel cans is the new pop product. With the traditional three-piece cans than steel two-piece cans obvious advantages, the “two-piece” more advanced manufacturing technology, production faster, higher yields and lower costs. Aluminum is relatively speaking, lower prices of some steel; steel two-piece cans does not have welding, is a whole, not afraid of leakage is beneficial beverage shelf-life.
Steel cans are environmentally friendly, high-tech beverage packaging, products can fully replace imported aluminum cans, and the relatively low production costs, and meet the country’s industrial policy is a replacement product of aluminum cans, the market prospect is broad.
Paper cans cause material revolution
Compared to aluminum cans, steel cans saves the space is not great, but paper cans instead of aluminum cans is very obvious advantages. Aluminum cans paper cans cost is only about 20%, can be small batch production, but also for small and medium production.
In 2002, the Beijing New Technology Institute leading engineers and technicians successfully developed China’s first production line of paper cans. The paper cans of cheap straw pulp production line is the main raw material, similar to the principles of the alloy, with appropriate accessories made from pulp, by choosing different mold, after the die casting line, to dry and shape, and then finishing, coating, Serve easily degradable paper cans. Its strength, hardness, toughness is very good, superior performance. The technology obtained many national patents and by national technical supervision departments of the strict test inspection, environmental protection and materials is considered a revolution in the field.
Heilongjiang Province, Shangzhi use waste straw resources in rural areas, developed with straw as the raw material of paper cans, in compression, leakage, wrestling, sealed, aluminum roof off in terms of packaging products in China through quality supervision and inspection at the testing center and has successfully passed the beer filling test, the project is currently on paper can produce 720 million cans.
Cans in appearance and use of paper with not much difference between aluminum cans, but its outstanding feature is the pop market has injected new vitality. Experts predict that China’s annual demand for paper, cans will gradually reach 15 billion, and broad development prospects.
