Technology expert reveals the mystery of wine bottle caps

In the long history of the Chinese nation, wine has always been at the forefront of the world, writing its own glorious chapter. The variety of alcoholic beverages on the market today has already become a bright spot to attract people's attention. Fine bottle caps and unique bottle types add a lot of color to them. As a small part of the packaging, the bottle cap plays a vital role in ensuring the product quality and shaping the product's personality. It can be said that “the bottle cap is small, but it is the finishing touch.”

Zhuhai Special Economic Zone Longshi Bottle Cap Co., Ltd. (hereinafter referred to as Longshi) is a modern enterprise specializing in the development, development and production of various bottle caps. The company has modern production equipment and advanced production technology, and has now developed a variety of Patented product. In February 2008, Mr. Hu Lixue, the head of Longshi Technology, accepted an exclusive interview with the reporter and both parties communicated on some technical issues of the bottle cap and screen printing.

Aluminum and plastic, water and fire? Or fish and sea?

Liquor bottle caps are mainly made of aluminum and plastic. The structure of plastic caps is complex, with anti-backup function, and the surface treatment methods are various. The appearance is unique and novel and the three-dimensional sense is strong. The disadvantage is that it is difficult to achieve high sealing performance, it is difficult to recycle, and it is unfriendly to environmental protection. In comparison, aluminum bottle caps can overcome the above-mentioned deficiencies of plastic bottle caps. Aluminum anti-theft caps have a simple structure, strong adaptability, good sealing, no pollution, and good anti-counterfeiting effect. They can also be recycled and used, but aluminum bottles The lid also has some defects, such as the different colors on the side of the bottle cap, easy to produce paint off, and lack of change in appearance. In an interview with HC360.com, Mr. Hu Lixue, head of technology at Dragon Lions, analyzed that: “The combination of two materials used to complement one another is the best choice for bottle cap manufacturing companies. This is the current production method used by the Lions. Combining quality with plastic, combining the advantages of the two in one, makes the product functional, and the appearance of high-end appearance."

Unique anti-counterfeiting technology, personalized equipment use

With the increasing protection of property rights and anti-counterfeit awareness, the anti-counterfeiting of alcoholic products has been increasingly emphasized by manufacturers. Bottle caps are part of alcoholic products, and their anti-counterfeiting functions and production methods are also diversified and gentrified. .

“At present, the industry mainly uses off-magnetism and lead-cutting technologies to achieve the security of bottle caps, and Long Lion has taken a different path and developed a hidden anti-counterfeiting technology,” said Hu Lixue, who is very proud to say, “This technology uses physical principles, Create a small edge on the edge of the cap. Before the bottle is opened, the small edge will be found inside the cap. When the cap is opened, the small edge will be exposed. restore."

In addition to the unique anti-counterfeiting technology, the use of the equipment by the Dragon Lion is highly personalized. “There is an undoubted fact that there is a gap between domestic printing equipment and foreign printing equipment. Production efficiency is low, the degree of automation is low, and the quality is somewhat poor. It is a common problem in domestic equipment. The Dragon Lion is still mainly using domestic equipment. Although domestic equipment is inferior in quality to foreign ones, it is low in cost, and Long Lion will modify the equipment for different products to make it more applicable."

Overprinting - future trends in bottle cap printing

There are many bottle cap pattern printing methods, such as silk screen printing, hot stamping, pad printing, etc., and various printing methods have their own characteristics and scope of use. For Long Lion, Hu Lixue said, “bronzing is based on its aluminum materials. As well as the wide adaptability of plastics and the good glossiness of printed products, it has become the main bottle cap printing technology currently used by the Lions."
