Aluminum Anti-theft Bottle Cap Industry Introduction

Since Stelvin successfully developed screwcaps for wine in 1984, more and more wine producers have gradually adopted its Stelvin screwcaps. At present, the global sales of this bottle cap has exceeded 10 billion, and it has maintained a rapid growth momentum in recent years. Aluminum anti-theft bottle caps have gradually replaced the cork market with their own advantages 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.

1: Strong sealing The inner pad of the aluminum anti-theft bottle cap uses a special sealing material. 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 the fruity aroma. No chemical substances will be produced even if the storage time is long. At present, the main sealing gaskets on the market are: Saran/tin and Saranex. The main components of the two gaskets are foamed PE materials, which have high elasticity and can meet the error size between different bottle mouths, ensuring the sealing effect.

2. Healthy and environmentally friendly The gasket of the aluminum anti-theft bottle cap, which contacts the wine, is coated with PVDC with a thickness of 0.20µm. It is characterized by stable quality, acid resistance, alcohol resistance, compliance with food hygiene packaging standards, and compliance with US FDA requirements. Keep the wine fresh.

3. Convenient to use The aluminum anti-theft bottle cap is easy to open and does not require special tools. If a cork is used to seal, a special opener is required, which wastes time, and sometimes the cork breaks and cannot be opened. If the bottled wine is not finished at one time, the aluminum anti-theft bottle cap can be simply screwed tight; if it is a cork, it is very difficult to re-plug and re-open, and bacteria will enter.

4. Short production cycle and low cost The production process of aluminum anti-theft bottle caps is aluminum plate-coating printing-stamping-rolling glazing-knurling-pad-counting packaging. Each process can achieve mechanized mass production with high output, while the production cycle of corks is long. The cork process is raw material collection - raw material air drying - raw cork steaming - primary processing - fine processing - post-processing. It takes 6 months to air dry the raw materials. The processing technology is complicated and cannot be mass-produced using automated machinery. 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.

Conclusion: Wine sealed with screwcaps tastes better than wine sealed with corks
