The biodegradable plastic pepper ball is made of PLA material, which can be decomposed by bacteria in soil or humid environment and will not pollute the environment, but the manufacturing method of biodegradable plastic pepper ball is completely different from POM plastic pepper ball.

The shrinkage rate of PLA-degraded plastic pepper balls is greater than POM plastic pepper balls, so the production of PLA plastic pepper balls cannot be shared with plastic pepper ball molds of other materials, and a separate mold should be made to produce them. During the injection molding of PLA plastic pepper balls, the materials should be fully dried. If there is moisture in the materials, the materials will be gasified during the injection processing, making it difficult for injection molding. The grinding machine used for PLA plastic pepper balls is different from that used for POM plastic pepper balls. The grinding machine used for PLA plastic pepper balls can only be used for manual pressure grinding, while POM plastic pepper balls can use hydraulic pressure as power to pressurize the grinding machine.
