PP pepper balls can be divided into solid plastic PP pepper balls and hollow plastic PP pepper balls according to their functions. The weight calculation method of PP plastic pepper balls is that the volume * density is the weight of solid plastic PP pepper balls, but the weight calculation method of hollow plastic PP pepper balls is very different from that of solid pepper balls, because the density of hollow plastic PP pepper balls is not fixed, so it is not possible to get an accurate result by using a fixed formula to calculate the weight of hollow plastic PP pepper balls.
