Application of aluminum anti-theft bottle cap in wine

as we all know, corks are generally used for packing wine bottles. However, since the successful development of the screencap for wine by stelvin company in 1984, more and more wine producers began to gradually adopt the stelvin screencap (Note: the bottle cap is an aluminum anti-theft bottle cap with a special cushion). At present, the global sales volume of the bottle cap has exceeded 1billion, and has maintained a rapid growth momentum in recent years. With its own advantages, aluminum anti-theft bottle caps have gradually replaced the cork market and become another major theme of wine packaging. The following is a brief introduction to the advantages of aluminum anti-theft bottle caps in wine packaging

I. sealing performance

in the past, many people thought that cork was the best cork for bottled wine. Cork is the best way to not completely isolate the air, which is conducive to the development and aging of the wine in the bottle. Recently, southrop wine company of Australia released the latest research results: oxygen is not necessary during the continuous development of bottled wine. For the development of high-quality wine, the most ideal cork should have stable low permeability or even zero permeability. The most commonly used bottle stoppers in the wine industry (mainly referring to traditional natural corks and synthetic stoppers) have either too high permeability or unstable permeability. And there are errors in different bottle mouths, and the different elasticity of cork leads to different sealing degrees

the inner cushion of the aluminum anti-theft bottle cap is made of special sealing materials. Its low permeability and zero permeability effectively prevent the oxidation of the wine in the bottle, and keep the wine fresh and retain the fruit fragrance. No matter how long the storage time is, no chemicals will be produced. At present, saran/tin and saranex are mainly used as sealing gaskets in the market. The following figure shows the indicators of oxygen permeability and water permeability of sealing materials:

note: 1. Oxygen permeability is the oxygen permeability per square meter for 24 hours under normal atmospheric pressure and 23 ° C

2. Water permeability refers to the amount of pervious steam per 24 hours at 23 ° C and 93% humidity

(1) saran/tin gasket PVDC coating contacts with wine to ensure the health and environmental protection requirements of wine

tin material has the characteristics of zero permeability, which ensures that the wine is completely isolated from the outside air and prevents the wine from being oxidized

(2) check whether the gasket at the joint is completely

this gasket is suitable for packaging wine with a storage period of more than 10 years

(2) saranex has two layers of PVDC and saranex polymer. Its low permeability is suitable for packaging and storage for a short period. This time, Jinan new era Gold Testing Instrument Co., Ltd. will share with you the structure and operation method of the concrete pressure testing machine in 10 years

the main component of the two gaskets is foamed PE material, which has a high degree of elasticity, and can further improve the error size between the ports to meet the market competitiveness of different bottles. So how to distinguish the bandwidth of a system and the concave convex of the sampling rate? The sealing effect is proved

II. Requirements for health and environmental protection

the raw material of cork is the bark of Quercus variabilis, which is mainly concentrated in the Mediterranean region. Quercus variabilis reached the bark stripping stage after 25 years of age. And the stripping cycle shall be at least 9 years. So raw materials are in short supply. With the continuous improvement of people's material and cultural living standards, less and less liquor is consumed, more and more wine is consumed by people, more and more corks are used, and resources are facing depletion. The cork after use can not be recycled, resulting in environmental pollution. Bauxite is relatively rich in resources. After the aluminum anti-theft bottle cap is used, it can be recycled without causing environmental pollution

after the wine packed with cork has been stored for many years, the bottled wine sealed with synthetic cork is generally oxidized, while the wine sealed with natural cork is highly polluted by oak, because the cork will produce a compound TAC (trichlorobenzyme) during storage. The thickness of the gasket of the aluminum anti-theft bottle cap in contact with the wine is 0.20 μ M PVDC coating, which is characterized by stable quality, acid and alcohol resistance, conforms to food hygiene packaging standards and meets the requirements of FDA. Keep the wine fresh

III. easy to use

the aluminum anti-theft bottle cap is easy to open without special tools. If a cork is used for sealing, it is inconvenient to open, a special opener is required, and time is wasted. Sometimes the cork is broken and cannot be opened. There are more and more occasions to drink wine, especially in wedding banquets, picnics, aviation wine and other occasions. Sometimes there is no opener, which is very inconvenient to drink

if the bottled wine is not drunk at one time, simply screw the aluminum anti-theft bottle cap tightly; If it is a cork, it is very difficult to re plug and re open it, and bacteria will enter it

IV. production and cost

the production process of aluminum anti-theft bottle cap is aluminum plate coating printing stamping roller printing polishing knurling padding counting packaging. Each process can realize large-scale mechanized production with high output. At present, our company has seven full-automatic coating printing production lines and six roller printing production lines, and processes more than 5 million aluminum anti-theft bottle caps per day

and the cork production cycle is long. Cork cork process includes raw material collection - raw material air drying - raw cork cooking - primary processing (sorting, cutting, punching and sorting) - finishing (grinding, cleaning, drying and grading) - post-processing (hot stamping, surface treatment, counting, sterilization and packaging). It takes 6 months for raw materials to be air dried. The processing technology is complex, so it is impossible to use automatic machinery for large-scale production, and the production batch is small. Aluminum anti-theft bottle caps cost 5-6 cents each, while synthetic corks cost 8 cents, and high-end natural corks cost at least 12 cents

v. expert conclusion

the flavor of wine sealed with screencap is better than that sealed with cork

this conclusion was drawn from an expert wine tasting activity organized by international wine magazine. The wine tasting event organized by international wine magazine is to solve the dispute between cork and screencap. The wine tasters employed by the organizer are internationally renowned wine tasting experts, including Michel Rolland and Peter Gago, the famous wine consultants of Penfolds The experts tasted 40 kinds of wine. Each wine was sealed in four forms: natural cork, synthetic cork, screencap and ordinary wine bottle cap. According to the evaluation results, experts gave high praise to 21 kinds of wines sealed with screencap. Among them, Penfolds wine made in Australia in 1996 sealed with a screencap was one of the highest score winners, and 77% of the evaluation experts gave it high praise
