PP pepper balls are mostly produced by injection molding technology, but the quality of PP pepper balls produced by different manufacturers is different. Except for the same brand of PP materials, the biggest difference is that some pepper ball manufacturers use nozzle materials to reduce production costs, and the PP pepper balls made from nozzle materials are not up to standard in environmental protection, which also has a great impact on the strength of PP pepper balls.If the PP pepper ball wins with the nozzle material, it is easy to cause the heavy metal content of the pepper ball to exceed the standard, and the application factories of the PP pepper ball are all used in food, medical care and other fields. If the PP pepper ball is not environmentally friendly, it will cause great damage to people's health. All the PP pepper balls manufactured by our company are made of PP materials that meet FDA standards, and the appearance of the products is basically translucent. In order to cover up the fact of using the nozzle material, some plastic ball manufacturers usually process the PP pepper ball into it.
