The country is now advocating environmental protection, and catering and takeaway businesses are gradually replacing ordinary disposable lunch boxes with degradable lunch boxes. So what is a degradable lunch box?

The degradable lunch box refers to a lunch box that can undergo a biochemical reaction under the action of the natural environment to eventually form carbon dioxide and water. The entire degradation process can be decomposed into harmless substances without human intervention.

Common degradable lunch boxes include the following categories:

1. Starch-based degradable lunch box

It uses starch as the main raw material, adds plant fiber and special additives, and is processed by chemical and physical methods to make a biodegradable snack box. Because starch is a biodegradable natural polymer, it is decomposed into glucose under the action of microorganisms, and finally decomposed into water and carbon dioxide. In addition, the material blended with it is also a fully degradable material, so it can be said that it has no impact on the environment. The main source of raw material starch can be corn, potatoes, sweet potatoes, cassava and other plants.

2. Biodegradable plastic lunch box

This kind of disposable lunch box is made of degradable plastic processed by adding other additives to biodegradable raw materials such as PBAT and PLA. From a long-term perspective, degradable plastics are completely decomposed into carbon dioxide and water under biological action, which is harmless to the natural environment
