Plastic Bottle Cap is a common form of packaging for bottles, cans, and barrels, especially in the fields of beverages, chemicals, and medicine. According to their uses, they can be divided into air-permeable plastic caps and air-impermeable plastic caps.
Plastic Bottle Cap generally use polyolefin as the main raw material, and are processed by injection molding, hot pressing and other processes. Plastic anti-theft caps are 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 testing by production units.
