Lightweight and easy-to-open plastic anti-theft caps for beverage packaging are not only convenient for consumers but also accelerate the development of the beverage industry. Domestic enterprises have introduced foreign equipment one after another and started the large-scale production and application of plastic anti-theft covers. However, the current aluminum cover site is still large. Some wine companies even cast a 35% cost on aluminum caps
Not long ago, a media broke the news that a well-known liquor company actually dropped 35% of its production costs on bottle caps. Whether this news is conclusive or not, the role played by the small bottle caps in the entire wine industry cannot be underestimated, and the anti-theft caps have also evolved from the spark of the year to the prairie fire.
Recently, the reporter learned from the China Brewery Association that in recent years, China's liquor production has been around 6 million tons, of which about 50% of wine bottles use anti-theft covers. In the past, the main raw material for anti-theft caps was aluminum, but since the mid-1990s Coca-Cola used plastic anti-theft caps instead of aluminum caps, plastic anti-theft caps have also been pushed to the forefront of beverage packaging. The future anti-theft cap is in the end the world of aluminum, or plastic world?
Zhang Liwen, an expert in the optimization of aluminum caps for the anti-theft caps, told reporters that at present, the bottle caps of Chinese liquor, wine, wine, and beverages are mostly made of aluminum. This is due to the fact that wines and beverages packed in glass bottles are mainly used, and the thermoforming process is adopted, the error in the size of the bottle mouth is large, and aluminum can achieve relatively high sealing performance. Zhang Liwen introduced that at present, there are tens of thousands of liquor production factories in China, of which there are more than 30,000 liquor production factories. In recent years, the annual output of liquor is about 6 million tons, of which about 50% are wine bottles. Use a security cover.
According to relevant experts, China's anti-theft caps will increase at a rate of 10% per year. By 2010, it is estimated that 15 billion anti-theft caps will be required, and about 60,000 tons of aluminum plates will be needed.
Zhang Liwen said that in terms of raw materials, the cost of aluminum is lower than that of plastic (the cost of an aluminum lid is about one-half of a plastic bottle cap), and the structure of the anti-theft cap is very complicated. The current production line is According to the needs of the installation of aluminum cover design, replaced by a plastic cover, not only the cost of raw materials, but also includes a series of issues including the transformation of the production line, bottle mouth, bottle cap redesign. Therefore, companies are less willing to spend their energy and financial resources to carry out these transformations. The aluminum anti-theft bottle cap is made of high-quality special aluminum alloy material, which has excellent performance, can be mechanized, large-scale production, and no pollution, and can achieve 100% recycling, but also meet the special requirements of high-temperature cooking sterilization.
In addition, aluminum caps also have a tendency to replace cork stoppers. Aluminum caps that do not require special tools have already been favored by many wine companies.
Plastic anti-counterfeiting bottle caps cannot be tightly attached to thermoformed glass bottles, making it difficult to achieve high sealing performance. Because plastic caps can easily absorb the dust in the air, together with the debris generated during welding, it is difficult to eliminate. At present, there are no complete solutions to the problems of plastic debris and dust pollution on wine. At the same time, some plastic bottle cap producers do not add environmentally friendly raw materials to plastics in order to reduce costs and cannot protect the health and safety of consumers.
But plastic security covers are not without merit. The structure has anti-backflow function, a variety of surface treatment process, strong three-dimensional sense, unique shape, lightweight and easy to open.
Aluminum caps and plastic caps are different. However, experts said that for a long period of time, aluminum is still the best choice for anti-theft cap manufacturers.
The aluminum lid must also be plastic. Since the mid-1990s, Coca-Cola's PET bottled drinks have used plastic anti-theft caps instead of aluminum caps to push the plastic anti-theft caps to the front of the beverage packaging. Since then, domestic packaging companies and beverage manufacturers have introduced foreign equipment and started mass production and application of plastic security covers. Today, lightweight and easy-to-open plastic anti-theft caps are used for beverage packaging, which not only facilitates consumers but also accelerates the development of the beverage industry. According to reports, at present, China's plastic cover production technology has reached the world's advanced level. The world-renowned plastic cover machinery has entered China. At the same time, the struggle between injection molding and compression molding has also begun in the production of plastic bottle caps. The industry believes that technological innovation has become the driving force for the rapid development of plastic anti-theft caps.
And sometimes, the role of plastic in the cap is irreplaceable. According to reports, almost all aluminum caps now require plastic caps. Because of investigations, people now prefer plastic caps and rubber caps with strong security and good openness. Although the profit of a plastic cap is only a penny, and the cap of a bottle is only a few cents, there are countless companies engaged in plastic bottle caps and plastic caps. Many companies find that a small plastic cover contains a huge market.
Bottle Innovation Brings Bottle Cap Revolution Because many companies use glass bottles to choose aluminum lids instead of plastic lids, industry insiders point out that if bottle materials are upgraded, the selection of bottle caps will be more diversified. Recently, two companies have jointly developed a plastic high-seal screw cap suitable for large-capacity high-density polyethylene bottles. The bottle cap is provided with a pull-type annular plastic sealing film. When the consumer opens, the cap can be removed without rotating the bottle cap, and then the ring-shaped membrane at the bottle mouth can be pulled to open the bottle. According to reports, this new type of bottle cap has good sealing performance, anti-theft function, and lower cost than aluminum sealing caps. At the same time, it does not need to purchase special sealing equipment to adapt to the existing cap production equipment. Survey shows that 80% of consumers choose this kind of bottle cap.
From a global perspective, according to a new research report from AMI Consulting, in the next five years, the global output of plastic caps and stoppers is expected to grow at an average annual rate of 5.6%, while the output of metal caps and stoppers will increase. The growth rate is only 3%.
According to reports, plastic caps are mainly divided into plastic caps, monolithic hot filling caps and combination caps.
As far as energy consumption, material consumption and environmental protection are concerned, in the beverage industry, compression-molded lids are undoubtedly the development direction of the present and future lid-making methods. At present, the compression molded caps account for more than 80% of Coca-Cola, Pepsi, Unity, and Master Kong, while Wahaha's tea beverages and soft drinks, Huiyuan PET bottled juices, etc., use compression molded covers to reach 100%. Compression molding and lidding technology accounted for 70% of the global share, accounting for more than 60% of China's share. Although the injection molding machine has adopted price cuts and other preferential measures to promote sales, the development trend of the compression molding process has continued unabated. From 2001 onwards, Chinese customers purchased more compression molding equipment than injection molding equipment.
Because the bottle mouth tolerance is difficult to control to the expected range, almost 100% of PET hot-fill bottles use two caps. From the end of the last century, many companies tackled the problem and tried to replace it with a single chip.
Since 2002, the world's petrochemical raw materials have generally risen in price, while the price of bottle caps in China has decreased. This spurs people to seek new technologies to reduce costs. The compression molding process has the advantages of accurate cap size and small bottle neck shrinkage factor.
It is also an inevitable trend that technological achievements are presented in fashion. The new combination cover will emerge in a timely fashion in the beverage industry, which will make China's beverage bottle more abundant.
However, the aluminum lid, plastic lid who is ups and downs, the future who will be responsible for the ears, the current may not be the time to draw conclusions.
