Now the country is promoting environmental protection, catering and take-out businesses have gradually replaced ordinary disposable meal boxes with biodegradable meal boxes, so what is a biodegradable meal box?
Biodegradable lunch box refers to the lunchbox that can undergo biochemical reactions under the action of natural environment and eventually form carbon dioxide and water. The whole degradation process can be broken down into harmless substances without manual involvement.
Common biodegradable meal boxes include the following categories:
1. Starch-based degradable meal box
It takes starch as the main raw material, adding plant fiber and special additives, through chemical and physical methods to make biodegradable fast food box. As starch is a biodegradable natural polymer, it is decomposed into glucose and finally water and carbon dioxide under the action of microorganisms. In addition, the material blended with it is also fully degradable, so it can be said that it has no impact on the environment. The main source of raw material starch production, can be corn, potato, sweet potato, cassava and other plants.
2. Degradable plastic meal box
This kind of disposable meal box is made of biodegradable plastic processed from biodegradable raw materials such as PBAT and PLA by adding other additives. In the long term, biodegradable plastics are completely decomposed into carbon dioxide and water under biological action, which is harmless to the natural environment.
