PVC plastic pepper balls are transparent after raw materials are processed in their natural colors. However, due to the poor control of temperature and processing time in the production process, the color of PVC plastic pepper balls often turns yellow, which affects the quality of PVC plastic pepper balls.

The reason for the yellowing of PVC plastic pepper balls may be due to the high temperature of the injection molding machine and the denaturation of the material during the melting process of the injection molding machine, or it may be caused by the material being in the barrel of the injection molding machine for too long during the injection molding. Generally, by adjusting the temperature and time of the injection molding machine, the problem of the yellowing of PVC plastic pepper balls can be well solved.
