In the third category, the small edition of Zhonghua packaging bottle net has to provide tinplate cover, which is generally based on the canned products with wide packaging.

So, what is the production market of plastic caps and what is the future market prospect? First of all, the cost of plastic caps is dominant, and it is difficult for other types of caps to break through the advantages of plastic caps on this point, which is the main guarantee to ensure their future market prospects. Secondly, the plastic bottle cap is simple and convenient to use, and the screw cap can be unscrewed easily, which makes it difficult to replace its image in the hearts of consumers.
