The first is the worrying health condition. Food and drug regulatory agencies often publish news that plastic lunch boxes contain harmful flora such as Escherichia coli.

Second, plastic lunch boxes contain a large number of unstable plasticizers or shaping agents, which will release substances harmful to the human body when hot soup and hot rice are encountered.

Third, it is difficult to degrade. Plastic lunch boxes are generally discarded as garbage after use. At present, there is no very scientific classification and degradation measures in China. Generally speaking, it can only be buried or weathered, and it takes decades or more than a hundred years, which seriously affects our living environment.

I hope I can help you.
