Some hollow plastic pepper balls are used as sealed accessories in liquid, and they need to have certain pressure resistance when used in liquid. If the pressure resistance of the hollow plastic pepper balls is not enough, the hollow plastic pepper balls will be deformed, and some even leak, so that the inside of the hollow plastic pepper balls will enter the liquid and lose the role of plastic floating balls. Therefore, the pressure resistance of the hollow plastic pepper balls is the most important data of the technical indicators of the hollow plastic pepper balls.

There are several factors that affect the compressive strength of hollow plastic pepper balls. The first is the material. If the material strength is not enough, the produced plastic hollow pepper balls are easy to deform under pressure. The second factor is the wall thickness of plastic hollow pepper balls. Simply put, the thicker the wall thickness, the higher the strength. However, when the wall thickness exceeds a certain limit, the specific gravity of plastic hollow pepper balls increases, so they cannot float on the liquid. Therefore, the wall thickness needs to be controlled within a certain range. After solving these two factors, the problem of compressive strength of hollow plastic pepper balls is solved.
