PA plastic hollow pepper balls have a hollow structure inside, and a few plastic hollow pepper balls will crack in the process of use. The main reasons for the cracking of the hollow pepper balls are the poor toughness and insufficient strength of PA materials. Besides the temperature during injection molding, the improvement method also needs special post-treatment technology to improve the cracking of the hollow pepper balls.

After the PA plastic hollow pepper ball has just been processed, the PA material becomes brittle and easy to crack due to the loss of water. The important measure to prevent the PA plastic hollow pepper ball from cracking is to humidify the PA plastic hollow pepper ball. There are two methods to humidify the PA plastic hollow pepper ball. One method is to soak the PA plastic hollow pepper ball in water, so that the plastic hollow pepper ball can naturally absorb water. Either way, When the water absorption of PA plastic hollow pepper ball reaches more than 0.1%, the toughness of PA plastic hollow pepper ball increases, which basically solves the phenomenon of cracking of PA plastic hollow pepper ball.
