Cork has been used in wine for a long time. The cork has several characteristics. First of all, the cork has air permeability, which enables the wine packed by the cork to breathe with the outside world. Secondly, the cork expands with heat and shrinks with cold. Of course, there are also disadvantages of wooden plug, that is, it is troublesome to open the wooden plug, which requires certain skills and tools to open it well. And the price of cork is generally high.
Plastic corks also have their own advantages. One is that they can be opened easily without external force and tools, which reduces unnecessary troubles. The second is that the price of the corks is cheap, and the price is lower than that of the wood corks. However, the safety of the materials used for a long time is still questioned. At the same time, the plastic corks do not have the wood fragrance that the wood corks should have.
