The vast market of aluminum bottle caps

The demand for aluminum bottle caps grows rapidly

At present, most of the packaging of liquor, wine, medicinal liquor and beverage in China is still glass bottles, so many caps are made of aluminum materials.

At present, our country each kind of alcoholic drink production factory already tens of thousands, among them liquor production factory about more than 30,000.

According to the statistics of China Brewing Industry Association, the annual output of baijiu in recent years is around 6 million tons, among which about 50% of bottles use anti-theft aluminum caps.

There are nearly 200 aluminum bottle caps production plants in China, with an annual designed production capacity of about 9 billion, among which nearly 30 production lines have been introduced and the output is more than 5 billion, which can produce nearly 100 kinds of bottle caps.

Two, wine favors aluminum anti - theft cover

In recent years, wine anti-counterfeiting has been paid more and more attention by manufacturers. As a part of packaging, wine bottle caps have diversified and advanced anti-counterfeiting functions and production forms. Torsion, open-type, multi-anti-counterfeiting and other wine bottle caps have been widely used by manufacturers.

Although the functions of anti-counterfeit bottle caps are constantly changing, there are two main types of materials used, namely aluminum and plastic.

Internationally, wine packaging bottle caps are mostly aluminum, simple appearance, fine production, give consumers elegant visual experience.

Compared with plastic bottle caps, aluminum caps are not only superior in performance, but also mechanized, large-scale, low-cost, pollution-free and recyclable.

Moreover, the aluminum bottle cap is simple in appearance, but fine in production. Advanced printing technology makes it consistent in color and design, giving people a delicate and elegant feeling.

Foreign wine bottle cap style is more traditional mode, less change, such as the bottle cap of Scotch whisky, the pure black with gold text, in giving people a simple, elegant, lasting enjoyment at the same time, but also played its due role.

The personage inside course of study thinks, go up with bottle cap in wine, aluminium character guard against theft cap still will be mainstream.

Plastic cover structure is complex, has the function of preventing backward irrigation, its surface treatment technology is various, strong three-dimensional sense, unique appearance, but its inherent defects can not be ignored.

Because the glass bottle adopts the thermal forming process, the size error of the bottle mouth is large, and it is difficult to achieve higher sealing.

Relevant packaging experts point out that, due to the existence of strong static electricity, plastic bottle cap is easy to absorb the ash in the air, coupled with ultrasonic welding when the debris is difficult to eliminate, plastic debris to the problem of alcohol pollution has not been completely solved.

In addition, in order to reduce the cost of individual plastic bottle cap manufacturers, in the raw materials mixed with false, sanitary conditions are worrying.

As part of the cap is attached to the glass bottle mouth, it is not easy to recycle, and environmental experts believe that its pollution to the natural environment is obvious.

In addition, plastic cap than aluminum cap, the cost of double or more.

In contrast, aluminum anti - theft cap can overcome the above - mentioned shortcomings of plastic cap.

Aluminum anti - theft cap structure is simple, strong adaptability, good sealing effect, not only can print colorful patterns, but also easy to achieve mass production, low cost, if the use of special, advanced printing, aluminum anti - counterfeiting cap anti - counterfeiting effect is also very good.

Of course, aluminum bottle caps also have some defects, such as different colors on the side of the bottle cap, easy to lose paint phenomenon, the appearance of the lack of change, but these problems can be found from the technical solution.

As a part of packaging, bottle caps have two main functions: first, they are airtight and protect the wine, which is the most basic function of bottle caps and the easiest for manufacturers to achieve.

Second, aesthetic, as an integral part of the package, a small cap can play the role of the finishing point.

At present, some manufacturers in the choice of bottle cap, too much emphasis on its anti-counterfeiting function, and neglected the most basic sealing function.

In fact, the anti-counterfeiting effect of a packaging product is related to its technical content, but the decisive role is not the product itself, but the national laws and regulations and consumers' sense of self-protection.
