In the past, wine packaging was mainly made of cork made of cork bark from Spain, plus PVC shrink cap. The disadvantage is good sealing performance. Cork plus PVC shrinkage cap can reduce the oxygen penetration, reduce the loss of polyphenols in the contents, and maintain its oxidation resistance; But it’s expensive. At the same time, the bark originating from Spain has poor reproduction capacity. With the increase of wine production and sales, cork resources are increasingly scarce. In addition, the use of cork is suspected of damaging the natural environment. At present, the caps of foreign wine bottles on the market adopt new processing methods and new designs, which are popular with the majority of users. Now let’s take a look at the characteristics of bottle caps in the application of foreign wine bottles?
1. Low cost, convenient processing, suitable for industrial production;
2. Good sealing performance, single film covering can store for about ten years; Double coated film can be stored for 20 years;
3. It is easy to open without special tools, especially suitable for today’s fast-paced society.
4. It has little impact on the environment, and aluminum anti-counterfeiting bottle caps will soon become the mainstream of wine packaging.
