New crown cap (on)

As the domestic beer industry is increasingly in line with international standards, international beer of world-class brands has entered the Chinese industrial market. The domestic beer varieties have also expanded rapidly in recent years, and are directly reflected in the fine varieties of beer, with pure taste and freshness. The quality improvement and guarantees are all due to the direct help of the crown cap. What is worth mentioning here is that Shanghai Ziquan Packing Co., Ltd. focused on the development prospects of the Chinese beer market a few years ago and established its own scientific research system to develop a series of crown caps to meet the needs of many varieties of high-demand beer. The new members meet the different needs of the market.
Pure bottle cap
Pure bottle caps are sterile bottle caps, which are developed and produced in line with the production of pure draft beer in the domestic market in recent years. Pure draft beer maintains its taste and nutrition and is setting off a huge wave in the Chinese beer market. Due to the change of pasteurization to membrane filtration in the production process of draft beer, the draft beer requires filling machine pipes, glass bottles, crown caps, and filling room air to achieve aseptic filling. Standards, especially the brewers’ strict control of the harmful bacteria in beer, have added strict microbiological testing items to the only packaging of crown caps that is controlled by the supplier.

For this reason, the production line for the production of sterile bottle caps using the high-heat, filter-sterilization method ensures that the aseptic caps produced are the green bottle caps that are most safe to use in the brewery.
Take the domestic pure bottle cap manufacturer as an example, Ziquan established a weekly inspection system for dust particles in the production line to ensure the safety of the production line and ensure the effectiveness of the aseptic caps, to ensure the cooling of the caps and the cleanliness of the packaging room. The sterilized condition of 10,000 grades is required to produce pure bottle caps; a professional microbiological testing room is established synchronously, and the total number of harmful bacteria and bacteria in beer is detected for each batch of caps, thereby ensuring the production of sterile caps. It is also the only microbial detection room in the domestic industry.
Oxygen Caps <br> As the beer is usually pasteurized, the tightness of the cap weakens as the storage time becomes longer, the air in the environment will gradually invade the beer, oxygen will reduce the freshness of the beer, Increase bitterness. As a result, the quality of high-end beer has been weakened. For this reason, bottle cap manufacturers and material suppliers actively cooperated with the test, and the production developed an oxygen bottle cap, which means that the bottle cap absorbs invaded oxygen during the shelf life of the beer, thereby achieving the same The shelf life of beer has the effect of extending the shelf life of fresh or same taste beer. Domestic Carlsberg beer uses oxygen bottle caps for more than a year and has been effectively protected on the taste of beer. It has maintained its own brand well.

The product feature of the oxygen-absorbing bottle cap is that an oxygen-absorbing substance is added to the gasket material of the bottle cap, and the oxygen-absorbing substance needs to be activated under the humid condition and can be kept stable under the normal storage condition before capping. Each gasket can absorb up to 2mg of oxygen, and the amount of oxygen-absorbing material migrating to the beer is very small. The oxygen-absorbing bottle cap absorbs the bottleneck and oxygen infiltrated from the outside to reduce the aging of the beer and make the beer more fresh and tasteful. To improve.
Stainless bottle cap
Crown caps are usually produced using tinplate. Anti-rust is protected by internal and external coatings. Due to collision scratches during manufacture, transportation, and use, the coating is damaged and exposes iron. Water, acids, etc. are easily encountered. Rusty. Anti-rust has become one of the requirements that most major breweries have paid attention to and strived to overcome. Once rusting problems of high-end beer and export beer could not be completely solved and they became the market's constraints.
