Plastic hollow pepper ball refers to a low-density plastic pepper ball product floating on the liquid, which is mainly made of plastic hollow pepper balls, and some of them are produced by plastic foaming technology. Plastic floating pepper balls are sometimes used under certain pressure. If the pressure resistance of plastic hollow pepper balls is not enough, it will cause the leakage of plastic hollow pepper balls.

The main reasons for the low compressive strength of plastic hollow pepper balls are that the wall thickness of plastic hollow pepper balls is thin, and the joints of plastic hollow pepper balls are not firmly bonded. Under pressure, the joints of plastic hollow pepper balls open, which leads to leakage. The solution is to increase the welding temperature of plastic hollow pepper balls in the welding process, and make the wall thickness of plastic hollow pepper balls as thick as possible, so that the phenomenon of insufficient pressure resistance and leakage of plastic hollow pepper balls can be well solved.
