Find aluminum can manufacturer

by admin

I want to buy an aluminum nitrate tank, a horizontal aluminum tank that can hold 60 tons of nitric acid. Where is the manufacturer in Northeast China? Our company is located in Jilin City, Jilin Province

Aluminum two-piece cans with easy opening lid are popular in liquid food packaging, especially in beer packaging, which has more momentum than traditional glass bottle packaging beer. Its development process is very worthy of serious summary. Especially at a time when we are vigorously promoting the packaging of beer in polyester bottles, we can change a perspective, that is, we can make an all-round comparison between polyester bottles and aluminum cans without sticking to the comparison between polyester bottles and traditional glass bottles. I’m afraid there will be more comparability between them, so we can further infer that since the beer packaged in cans is feasible from then to now, the beer packaged in polyester bottles must be feasible. This has to be convincing, and there is no lack of more theoretical and practical enlightenment for the promotion of polyester bottle packaged beer

the original beverage packaging cans were made of steel, which was later improved to aluminum. The material density of aluminum is 2.7, which is only 1 /3 of that of steel. Its extensibility is better. After the successful trial production of drawing & ironing (DI tank for short), it is possible to realize that the tank height is greater than the tank diameter (H is greater than D), so it has popularization value in the packaging of liquid food industry. However, since aluminum is located at the end of the sequence of the periodic table, once it contacts with other metals, the interface will be corroded due to the bimetallic potential difference. At the same time, it has certain instability for acidic beverages, including beer. Therefore, the coating in the tank has become a shielding structure that must be considered. At present, the finalized packaging materials are two cans, which are internally coated with 130mg epoxy resin for packaging beer (CO2 content is 5g /L), and internally coated with 180mg epoxy amino acid for packaging strong corrosion beverage (CO2 content is 8g /L). With the improvement and perfection of environmental protection standards, the structure of the easy to pull cover is also changed from the disposable pull ring (stay-ontab) to the combined button type (). The large-scale popularization and use of easy open cover two-piece can is closely related to the completeness and effectiveness of its recycling system, which is the result of the unremitting efforts of Alcoa for nearly half a century. The result is that only those packaging materials that effectively enter the resource recycling and circular economy system and meet the requirements of sustainable development are truly viable and can be accepted and respected by the public. This is the behavior guide that should be regarded as the highest purpose in today’s action to promote polyester bottle packaged beer

in a German beer manual, many advantages of cans are listed:

· not easy to break

· the mass is much lighter than that of glass bottles (355ml cans weigh only 14g)

· disposable packaging, effective recycling of raw materials

· can stack well

· opaque and light free taste

· packaged beer can be pasteurized after being sealed

to be fair, all the advantages of beer packaged in the above cans are the combination of polyester bottles, and polyester bottle packaged beer has many advantages that the latter does not have, such as:

· packaging equipment, which is used for the packaging of polyester bottles, The existing glass bottle packaging line can basically be used for both purposes after necessary design changes (in fact, there is a glass plastic bottle dual-purpose bottling line), while the pop can packaging must spend a lot of money to re purchase special packaging equipment

· with the same fixed liquid level filling, polyester bottles and glass bottles can have the same filling accuracy, while the filling accuracy of easy to pull cans is much lower because the diameter of the can body is much larger than that of the bottleneck

· in the filling process, polyester bottles have the same small opening area as glass bottles. Even if 209 is changed to 206 cover type, the opening area of can mouth is much larger than that of bottle packaging (directly proportional to the square of can diameter). Therefore, the oxygen increasing capacity of beer packed in cans is much higher than that of bottled beer

· polyester bottles and cans can not withstand vacuum pumping, and both use CO2 replacement to obtain low oxygenation, but polyester bottles can be filled stably under the liquid level of long tubes. People in the beer industry have always believed that this is an effective filling method with low oxygen content

· the change of polyester bottle type meets the market fashion, with more variety and convenience

you can also list many advantages of polyester bottles over cans. The conclusion is that the cost performance of polyester bottle packaged beer is much better than that of pop can packaged beer

the manufacturing of domestic aluminum two-piece cans began in 1985, with an investment of US $300 million and the introduction of 13 can production lines, with an annual production capacity of 11 billion aluminum cans. In 2003, there were 2 billion cans for tinned beer, about 600000 tons (kiloliters), accounting for 2.3% of the total beer production in China, with a year-on-year increase of more than 8%, which is higher than the average annual growth rate of 5 ~ 6%, reflecting the domestic safe, lightweight and beautiful one-time packaging market, which is expanding day by day. Can packaging beer is feasible, polyester bottle packaging beer must be feasible!
