Plastic anti-theft bottle caps are the common packaging form of bottle packaging at present, especially in the field of beverages. Generally, polyolefin is used as the main raw material, which is processed by injection molding, hot pressing and other processes.
Plastic anti-theft bottle caps are not only required to be easy for consumers to open, but also need 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 of plastic anti-theft bottle caps:
1. There is an annular leak-proof ring on the inner wall of the top of the bottle cap;
2. The lower end of the bottle cap is connected to an anti-theft ring through the tensile reinforcement;
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 bottle cap 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 bottle from being contaminated by bacteria, and can ensure that various beverage packaging meets the national health standards and other characteristics.
