Performance characteristics of plastic caps

Plastic caps are the most commonly used packaging forms for bottles, cans, and barrels, especially in the fields of beverages, chemicals, and medicine. According to their uses, they can be divided into breathable plastic caps and airtight plastic caps. The plastic cover is generally made of polyolefin as the main raw material, which is processed by injection molding, hot pressing and other processes. The plastic anti-theft cover not only needs to be easy for consumers to open, but also needs to avoid leakage problems caused by poor sealing performance. How to reasonably control the sealing performance of bottle caps is the focus of on-line or off-line inspection of production units.





Performance characteristics:
1. There is an annular leak-proof ring on the top inner wall of the general plastic cover; there are also ordinary plastic bucket covers that need to match 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 tensile 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 the characteristics of firm sealing, good leak-proof and anti-theft performance, safe and convenient use, can effectively prevent the liquid in the container from being polluted by the outside, and can ensure that the packaging of various liquid products conforms to national safety standards.
