Fashion evolution of beer cans packaging

tinned wine has superior sealing performance, is clean and hygienic, and can retain the fresh flavor of beer to a large extent within the shelf life of 12 months, so it has attracted more and more young and middle-aged urban consumer groups facing liquidation crisis in these industries

tinned beer is light and convenient to transport, carry and open, leading the trend of fashion consumption

the manufacturing of domestic aluminum two-piece cans began in 1985, with an investment of US $300million and the introduction of 13 cans production lines, with a production capacity of 11billion aluminum cans. In 2003, there were 2billion cans for tinned beer, an increase of more than 8%, higher than the growth rate of bottled beer of 5%, reflecting the expansion of the domestic high-end beer market

Budweiser and Qingdao are the largest users of cans for plastic film beer brands, with 200million and 400million cans respectively, of which Budweiser tins are rare in the world and the only corrugated cans in China, showing the uniqueness of global famous beer enterprises. Tsingtao Beer took the lead in launching 500ml cans in China. Through packaging innovation, it can better meet the needs of consumers for different capacity specifications

with tinned beer becoming more and more popular with consumers, the domestic can making industry has come out of trouble. Foreign aluminum cans such as ball, crown, Pacific, United and Shanghai Baoyi steel cans have jointly carved up the domestic beer metal container market

aluminum cans are mainly used

aluminum materials have good processability and printing adaptability, and are suitable for high-speed and continuous automatic production. Aluminum cans are rust free, corrosion-resistant, light tight, fresh-keeping and flavor preserving. The products are light in weight, safe in transportation and storage, easy to carry and use, and waste cans and old cans can be recycled, which is conducive to environmental protection. Tinned wine has excellent sealing performance, is clean and hygienic, and can retain the fresh flavor of beer to a great extent within the shelf life of 12 months, so it has attracted more and more young and middle-aged consumers in cities

ten processes are required for aluminum cans to be made into 0.28mm cans from coiled materials: Cup punching, stretching, thinning stretching (three times), cutting, primer, printing, closing and flanging. The process flow is as follows: the cup making machine makes the aluminum sheet into a cup: the stretching machine stretches and thins the cup into a white can, the cleaning machine cleans the paint for the white can, the external printer prints the can body according to the design style of different customers, the external printing oven dries the printed pattern of the can body, the can is internally coated through the internal spraying machine, the internal drying oven dries and internally sprays, the waxing machine waxes along the edge of the can mouth, the necking machine and flanging machine finally closes and flanges, Each finished product tank needs to pass the light inspection procedure. The computer light inspection machine will automatically remove the unqualified products, and the qualified cans will finally enter the automatic stacker for packaging. The speed of domestic can factories is above 900cpm

packaging process

the packaging process of tinned beer is simpler and easier to control than bottled and barreled beer. The main equipment of an automatic tinning line is composed of destacker, wine can roll sealer, sterilizer, packing machine/sealing machine, and the filling speed can reach 1000cpm

the technological process of beer Canning is as follows: the destacker unloads the empty cans of the code layer from the plastic tray, pushes them onto the plastic chain plate, enters the washing machine, rinses them with 80 ℃ hot water, dries them, and achieves sterility. Then, coz isobaric filling is adopted, and carbon dioxide is used to replace the air in the tank. After filling, carbon dioxide is sprayed to foam the tank mouth, and the cap is quickly sealed. The automatic quantitative instrument is used to detect the liquid level, followed by pasteurization (spray sterilization). The tins after filling are dried by the air dryer, and then the production time is sprayed on the bottom of the cans by the inkjet printer

according to the packaging form of packaging and becoming a domestic large-scale aluminum alloy material production base, different packing machines are used: the single die-cutting cardboard is a wrapping type, the earpiece is pressed onto one large side of the cardboard, the mechanical rod lifts the other large side and both sides in turn to wrap, and the hot sol quickly binds the manufacturer's seams and covers. When packing, the suction cup of the packing machine will absorb the large surface into a hollow, and the spreading rod of the machine will push the earpiece inward, and then glue it. This packing method is highly efficient and widely used abroad. The wrapping packing machine can also pack the thermoplastic film with paper bracket for packing. At this time, the packing machine needs to be equipped with a set of PE film cutting and printing, and it needs to be equipped with a photoelectric eye device. After automatic packing and bonding, OPP sealing tape is generally no longer used in the listening box. The typical 355ral tins are 24 cans, 18 cans and 12 cans, which are mainly determined by the habit of consumers to buy the whole box

modern filling

modern beer technology widely uses computer recognition system and digital display instruments to assist in mechanized filling operation, so as to ensure that beer quality is not affected in the filling process. The hearing remover can automatically detect the following manufacturing defects of the cans: oil, liquid, deformation, foreign matter, and odor, and remove the unqualified containers from the line. The consumption of plastic bags is still large, and unqualified products are still circulating in the market

empty cans are tested for liquid before washing, and the inner wall of empty cans is washed with clean brewing water

use C02 to wash the air receiver, prepare for pressure, and then pour wine; After the wine filling is over, it will be subject to pressure relief, bubble breaking, and then sealed and capped. The tolerance of 355ml internal volume should be controlled within ± 8ml, the coz should be between 2.65-2.85, the og should be 10.7-11.0, and the average TPO should be controlled below 134ppb. Wine filling and sealing are closely linked, and KHS is the majority of machine suppliers

the functions of HEUFT liquid level detector include detecting the overflow, listening to the internal volume, automatic sampling, and recording the number of filling defects of each wine valve

the beer sterilization process is divided into three parts: temperature rise, 62~c sterilization temperature and temperature drop. Improper sterilization affects the beer flavor. The quality indicators that should be controlled are: PU (8-10), MPT (141 ± OC), BOT ≤ 270C

the liquid level detection after sterilization is controlled by a fi~ec weight meter, which automatically picks out the tinned wine with insufficient liquid level. (to be continued)
