There are two kinds of plastic pepper floating balls commonly used, one is a plastic pepper foaming ball produced by foaming technology, and the other is a hollow plastic pepper ball with a hollow inside. The manufacturing technology of the two plastic pepper floating balls is different, which also causes great differences in price and quality of the two plastic pepper floating balls.

Plastic foamed pepper balls are produced by adding foaming agent to plastic raw materials, which has the advantages of high production efficiency and low cost. However, the yield of plastic foamed pepper balls is not high, and the precision of plastic foamed pepper balls is not high, which is easy to absorb liquid, resulting in unstable density, so the frequency of use is not high.

Plastic hollow pepper balls are made of plastic raw materials through blow molding or injection molding and welding. Because they are made of pure plastic, the density of plastic hollow pepper balls is very stable. Moreover, if plastic hollow pepper balls are made by mold hot welding, many kinds of plastic materials can be used to produce plastic hollow pepper balls. Plastic hollow pepper balls with different materials are excellent in temperature resistance, oil resistance and chemical resistance, and their application range is more than that of foamed plastic pepper balls. With mold hot welding, plastic hollow pepper balls are made.
