Plastic ball plastic degradation rate depends on the choice of raw materials, general plastic ball degradation total degradation and degradation of two half, the so-called degradation refers to the natural environment, plastic ball is the sun, water, and a process of powder hollow plastic ball after oxidation, the general degradation rate in a few years, some even hundreds of years, the degradable plastic ball the fastest plastic ball PLA production of degradable plastics, general degradation rate can be degraded completely in a year and a half, but the condition is PLA plastic ball to fully contact with water and soil, make a full production of bacteria the environment, so also can accelerate the degradation of PLA plastic ball speed.
