Aluminum anti-theft cap will become the mainstream of wine caps --------------------------------------- ----------------------------------------- 2005-08-05 09:51: 54 8 aluminum anti-theft cover will become the mainstream of wine bottles China's current liquor, wine, wine and beverage packaging are still mostly glass bottles, so many of the bottle caps are made of aluminum. At present, there are tens of thousands of liquor production factories in China, including about 30,000 liquor production factories. According to the statistics of China Brewing Industry Association, the annual output of white spirits in recent years is about 6 million tons, of which about 50% of bottles use anti-theft caps. China's aluminum cap production plant nearly 200, the annual design production capacity of about 9 billion, of which nearly 30 production lines introduced, the output is more than 5 billion, can produce nearly a hundred kinds of various types of caps. According to relevant experts, China's anti-theft caps will increase at a rate of 10% a year. It is estimated that about 15 billion anti-theft caps will be needed in 2010, and aluminum plates need to consume about 53,500-60,000 tons. In recent years, the anti-counterfeiting of alcoholic drinks has become more and more important for manufacturers. As part of the packaging, the bottle caps are also diversified and gentrified for their anti-counterfeiting functions and production methods. Bottle caps such as twist-off type, open type, and multiple security counterfeit bottles Widely used by manufacturers. Although the function of anti-counterfeit bottle caps is constantly changing, there are two main types of materials used, namely, aluminum and plastic. Internationally, most alcohol bottle caps use aluminum bottle caps, which are simple in shape and delicate in production, giving consumers an elegant visual experience. Compared with plastic bottle caps, aluminum bottle caps are not only superior in performance, but also can be produced in a mechanized, large-scale, low-cost, non-polluting, and can be recycled. Aluminium bottle caps are simple in appearance, but they are made in fine detail. The advanced printing technology makes them uniform in color and exquisite in design, giving people a sense of exquisiteness and elegance. The style of bottle caps used in foreign countries mostly adopts the traditional mode. Less change, such as the cap of Scotch whisky, its pure black and golden text, it gives people a simple, elegant, long-lasting enjoyment, but also it should have The logo function. The structure of the plastic anti-theft cover is complex, and it has the function of preventing back pouring. Its surface treatment process methods are various, the three-dimensional sense is strong, the appearance is unique and novel, but its inherent defects cannot be ignored. Due to the thermoforming process used for glass bottles, bottle head size errors are large, and it is difficult to achieve high sealing performance. Relevant packaging experts pointed out that due to the presence of strong static electricity, plastic caps are prone to adsorb dust in the air. In addition, debris generated during ultrasonic welding is difficult to remove. There is currently no complete solution to the problem of plastic debris on wine contamination. In addition, individual plastic bottle cap manufacturers have to worry about making their raw materials adulterated to reduce costs. As part of the bottle cap is connected with the glass bottle mouth, it is not easy to recycle. Environmental experts believe that its pollution to the natural environment is obvious. In addition, compared with aluminum bottle caps, the cost of plastic caps is about double or more. In contrast, aluminum anti-theft caps can overcome the above-mentioned shortcomings of plastic caps. The aluminum security cover has a simple structure, strong adaptability and good sealing effect. It can not only print colorful patterns, but also can be easily mass-produced. The cost is low. If a special and advanced printing method is used, the anti-counterfeiting effect of the aluminum security cover is also effective. well. Of course, aluminum bottle caps also have some defects, such as the different colors of the side of the bottle cap, easy to produce paint off, the appearance of a lack of change, but these problems can be found in the technical solution. Bottle cap as part of the package, its function is mainly two things: First, the seal, the protection of wine, which is the basic function of the bottle cap, but also easier for manufacturers to do; second is the aesthetics, As an integral part of the packaging, small caps can be the finishing touch. At present, some manufacturers in the selection of bottle caps, overemphasized its anti-counterfeiting features, and ignored its more basic sealing function. In essence, the effectiveness of sealing and anti-counterfeiting of a packaged product is closely related to its technical content, but it is not the product itself that determines the role, but the laws and regulations of the country and consumers' self-protection awareness. Aluminum anti-theft bottle caps are made of high-quality special aluminum alloy materials and are mainly used for the packaging of alcoholic beverages, beverages (gas-containing, non-gas-containing) and medicines and health products, and can meet special requirements such as high-temperature cooking and sterilization. Aluminum bottle caps are often processed in production lines with a relatively high degree of automation. Therefore, the strength, elongation, and dimensional deviation of the materials are all very strict. Otherwise, cracks or creases may occur during processing. In order to ensure that the bottle cap is easy to print after forming, the bottle cap is required to have a flat plate surface with no rolling marks, scratches and stains. The commonly used alloy states are 8011—H14, 3003—H16, etc., and the material thickness is generally 0.20— 0.23mm, width 449~796mm. The aluminum bottle cap material can be produced by hot rolling or continuous casting and rolling, respectively, and cold rolling. At present, China's anti-theft cover material production plant uses continuous casting and rolling stock production, but according to anti-theft cover manufacturers, the use of anti-theft cover material on the hot-rolled billet is better than the cast blank.
