What is the difference between degradable plastic bags and non-degradable plastic bags

The difference between the two is the difference in degradation rate.

Most ordinary people have misunderstandings about "non-degradable plastics"-plastics themselves are actually degradable. The raw material of ordinary plastic is polyethylene, which has high corrosion resistance and strong chemical stability. If it is discarded in the soil, it will take at least a long time to degrade. It's just that the degradation rate of plastics is too slow, so people feel that they are not degradable. However, this slowness in the context of massive use has also caused the current problem of plastic pollution treatment, which can not be degraded and degraded, and incineration will pollute the air.

The degradable plastics have made technological innovations in terms of degradation speed. By adding degradable masterbatch in the production process of traditional non-degradable plastics, the degradation speed of plastics is accelerated. Generally, complete degradation is achieved within 2 years, and the degradation process will not affect the environment. Cause harm.

In addition, because many degradable plastic technologies were relatively backward, they focused on degradability and ignored the performance of degradable plastic products. As a result, degradable plastic products using this technology generally exhibited the problem of poor quality and poor load-bearing and easy breakage. . However, this problem has been overcome by new technologies when the use of degradable plastics is becoming more widespread. The performance of degradable plastic products under the new degradation technology is basically the same as that of ordinary plastics.
