What is the wine bottle cap made of?
Bar polymerization plug: the cork particles are compressed into a stick and processed. This bottle stopper contains a high amount of glue and is inferior in quality to the plate polymerization plug. But the production cost is lower, and it is more common in developing countries.
The plate is made from cork plug: polymerization particles are pressed into plate after processing, physical properties close to the natural cork, rubber content is low, is a good bottle stopper, but the production cost is relatively high, the use of more in developed countries.
Polymerization plug: it is a cork made of cork particles and adhesives. According to the different processing technology, can be divided into plate polymerization plug and bar polymerization plug.
Fill plug: This is a kind of identity in the cork family is low, and it matches natural born the same, but because of relatively poor quality, the quality of the surface of the impurities in the holes will have an impact on the surface, with a mixture of cork powder and a binder in cork smear evenly, filled with cork defects and breathing holes. This bottle stopper is usually used to preserve wines of lower quality.
Plug: it is natural cork in the aristocracy, is of the highest quality cork, cork is composed of one or several pieces of natural cork processing, mainly used for sealing Wine and longer storage period of the Wine not containing gas. It is no wonder that the wine sealed with a natural stopper has been kept for decades, and the record of over one hundred years is not surprising.
