Is aluminum anti - theft cap better than plastic?

Aluminum anti-theft bottle cap is made of high-quality aluminum alloy material, which is mainly used for packaging of alcoholic drinks (including steam, without steam) and medicine and health products, and can meet the special requirements of high temperature cooking and sterilization.

Aluminum caps are mostly processed in highly automated production lines, so the requirements for material strength, elongation and dimensional deviation are very strict, otherwise there will be cracks or creases during processing.

In order to ensure that the bottle caps are easy to be printed after forming, it is required that the sheet surface of the bottle caps should be flat and free from roll marks, scratches and stains. The alloy states are generally 8011-H14, 3003-H16, etc. The thickness of the materials is generally 0.20mm ~ 0.23mm, and the width is 449mm ~ 796mm.

Aluminum cap material can be produced by hot rolling or continuous casting and rolling billet respectively, and then by cold rolling.

At present, continuous casting and rolling billets are used more frequently in Chinese manufacturers of anti-theft cover, which is better than that.

The relevant personage inside course of study introduces, our country guard against theft bottle cap will grow with the speed of 10% every year, about need guard against theft bottle cap 15 billion in 2010, aluminium sheet strip material 535000 ~ 60000 tons, development is very rapid.

Demand for aluminum caps is growing fast.

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

At present, our country each kind of alcoholic drink production factory already tens of thousands.

According to the data, the annual production of liquor in recent years is about 8 million tons, of which about 50% of the bottles use security caps.

Alcohol anti-counterfeiting has been paid more and more attention by manufacturers. As a part of packaging, wine bottle caps have diversified anti-counterfeiting functions and production forms. Torsion, opening, singing, talking and multiple anti-counterfeiting 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.

In the world, most wine packaging bottle caps are made of aluminum, characterized by simple appearance, fine production, advanced printing technology to make the color consistent, elegant design.

Compared with plastic bottle caps, aluminum bottle caps not only have good performance, but also have low cost, no pollution and can be recycled.

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.

Concerned packaging expert points out, because of the existence of strong static electricity, plastic bottle cap is easy to absorb the ash in the air, plus the detritus produced when ultrasonic welding is difficult to eliminate, plastic detritus to the problem of wine pollution has not been completely solved.

Additional, manufacturer of individual plastic bottle cap is cut cost, adulterate in raw material make false, wholesome condition is worrying, because bottle cap has a part to be connected with glass bottle mouth, recycle not easily, environmental protection expert thinks, it is obvious to natural environment pollution.

In addition, plastic cap compared with aluminum cap, the cost of high about times or more.

Compared with the development of aluminum anti - theft cap can overcome the above shortcomings of plastic cap.

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

Aluminum anti-theft bottle cap is made of high-quality aluminum alloy material, which is mainly used for packaging of wine, beverage (including gas, without gas) and medicine and health products, and can meet the special requirements of high temperature cooking and sterilization.

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.

Aluminum caps are mostly processed in highly automated production lines, so the requirements for material strength, elongation and dimensional deviation are very strict, otherwise there will be cracks or creases during processing.

In order to ensure that the bottle caps are easy to print after forming, it is required that the plate surface of the bottle caps is flat and free from roll marks, scratches and stains.

Aluminum cap material can be produced by hot rolling or continuous casting and continuous rolling, respectively, through cold rolling.

At present, domestic continuous casting and rolling billets are produced by domestic manufacturers of security caps. However, according to the manufacturers of security caps, hot rolled billets are better than cast-rolled billets in the use effect of security caps.
