Update:10 Mar 2022

Everyone will touch and use plastic bottle caps. Generally, we are more concerned about whether the small plastic bottle caps can really play a leak-proof role, and at the same time can protect the liquid or other things in the container from spilling out.


1. There is a ring-shaped leak-proof ring on the top inner wall of the general plastic cover; there are also ordinary plastic bucket covers that need to be matched with the inner cover, so there is no need to design a leak-proof ring; 2. The lower end of the plastic cover is connected to an anti-theft ring through a tension reinforcing rib ;
3. At the same time, there are several sheet-like gyratory tension wings evenly distributed on the inner wall of the anti-theft ring; the plastic bucket lid designed in this way has firm sealing, good leak-proof and anti-theft performance, safe and convenient use, and can effectively prevent the liquid in the container from being incompatible. Affected by external pollution, it can ensure that the packaging of various liquid products meets the national safety standards and other characteristics. Therefore, the plastic bottle cap can be used with confidence, and it will help us preserve the liquid in the container from other factors.
The bottle cap is an important part of food and beverage packaging, and it is also the first place consumers come into contact with the product. The bottle cap has the function of keeping the contents of the product closed, and also has the functions of anti-theft opening and safety, so it is widely used in bottled products, so the bottle cap is the upstream industry of the food, beverage, wine, chemical industry, and pharmaceutical industry. It is the key product of bottle container packaging. In the early development of bottle caps, cork materials, tinplate crown caps and unscrewing caps were used. Up to now, we have continued to develop aluminum long-neck aluminum caps, carbonated drink aluminum caps, hot-filling aluminum caps, injection aluminum caps, medicine caps, and open-top caps. Type ring caps, safety button claw caps and plastic bottle caps and other products.
