Application of aluminum anti-theft bottle cap in wine

as we all know, corks are generally used in wine bottle closures. However, since 1984, when stelvin company successfully developed the screencap suitable for wine, more and more wine producers began to gradually adopt its stelvin screencap (Note: the bottle cap is an aluminum anti-theft bottle cap with a special inner cushion). At present, the global sales volume of this bottle cap has exceeded 1billion, and has maintained a rapid growth momentum in recent years. Aluminum anti-theft bottle cap has gradually replaced the cork market with its own advantages to meet the comprehensive needs of customers, and has 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

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 in Australia announced the latest research results: oxygen is not necessary in 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 corks in the wine industry (mainly traditional natural corks and synthetic corks) either have too high permeability or unstable permeability. And there are errors in different bottle mouths, and the different elasticity of corks leads to different sealing degrees

the inner cushion of the aluminum anti-theft bottle cap adopts special sealing materials, and its low permeability and zero permeability characteristics effectively prevent the oxidation of the wine in the bottle, so that the wine remains fresh and retains fruity fragrance. No matter how long the storage time is, no chemical substances will be produced. At present, two kinds of sealing gaskets are mainly used in the market: saran/tin and saranex. 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 is the amount of pervious steam per 24 hours at 23 ° C and 93% humidity

(1) saran/tin gasket PVDC coating is in contact 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

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

(2) saranex two-layer PVDC and saranex polymer, with its low permeability, is suitable for wines with a packaging storage period of less than 10 years

the main component of the two gaskets is foamed PE material, which has high elasticity, can meet the error size between different bottle mouths, and ensure the sealing effect

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 entered the bark stripping period after its age reached 25 years. And the stripping cycle shall be at least 9 years. So the raw materials are in short supply. With the continuous improvement of people's material and cultural living standards, less and less alcohol is consumed, more and more wine is consumed by people, the consumption of corks is increasing, and resources are facing depletion. The cork after use cannot be recycled, causing environmental pollution. Bauxite resources are relatively rich. After the use of aluminum anti-theft bottle caps, they 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 to reduce the power noise, while the wine sealed with natural cork is highly polluted by oak, because the cork will produce a compound TAC (Trichlorobenzene methyl ether) 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 you haven't finished drinking the bottled wine 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. 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 cork production cycle is long. Cork process includes raw material collection - raw material drying - raw cork cooking - primary processing (sorting, cutting, punching, sorting) - fine machining and specimen removal (grinding, cleaning, drying, 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 a minimum of 12 cents

v. expert conclusion

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

this conclusion was reached by an expert wine tasting activity organized by international wine magazine. International Wine Magazine organized this wine tasting event to resolve the debate between cork and screencap. The wine tasters hired by the organizer are all 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 of which 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, Australia's 1996 Penfolds wine sealed with a screencap was one of the highest score winners, and 77% of the evaluation experts gave it high praise
