The difference between degradable transport bags and non-degradable transport bags
In 2020, the National Development and Reform Commission’s “Opinions on Further Strengthening the Control of Plastic Pollution”, more than 20 plastic products are used in the market, from non-degradable plastics to degradable plastics, and the plastic composition has undergone tremendous changes. How to distinguish between degradable plastic shipping bags and non-degradable plastic shipping bags?
The main raw materials used for degradable plastics are biochemical raw materials such as corn starch/cassava starch and methyl cellulose. Under normal natural conditions, the degradation time is about 100 days. That is to say, about 100 of the main components will be “oxidized”. Even if the degradable plastic bag is not used, it will degrade in five months. Under the standard of retting, even the newly produced degradable plastic transport bag can be degraded, converted into H2O and CO2, and finally absorbed by plants!
The main raw material of a non-degradable plastic transport bag is plastic raw material. Plastic raw material is defined as a synthetic or natural high molecular polymer, which can be arbitrarily kneaded into various shapes and can finally keep the shape unchanged. Material or plastic material product. Non-degradable plastic bags can remain unchanged for hundreds of years in the natural environment, which brings great environmental pollution to nature.
