Disadvantages Of Plastic Bottle Caps

The cap is made of plastic injection molding, which is called a plastic bottle cap. At present, the market share of plastic bottle caps on the market is very high, and many bottles are almost all made of plastic bottle caps. On the other hand, the price of plastic bottle caps is low and the cost is cheap, which is also the reason why plastic bottle caps are used in large quantities.

However, there are also many shortcomings in plastic bottle caps, and in general there are these aspects. First of all, the sealing performance of plastic bottle caps is not outstanding. Compared with tinplate caps and aluminum-plastic caps, there is a certain gap in the sealing performance of plastic bottle caps. Secondly, the pressure resistance of plastic bottle caps is poor, such as soft drinks and other products should not use plastic bottle caps. Thirdly, the anti-corrosion performance of plastic bottle caps is poor, and it is not suitable to use plastic bottle caps for the packaging of some chemical corrosion products. Finally, plastic bottle caps cannot withstand high temperatures, cannot be used repeatedly, and the material safety is poor.
