1. What is a biodegradable lunch box?

2. What are the main ingredients of biodegradable disposable lunch boxes?
There are two types of raw materials used in biodegradable lunch boxes: one is made of new stone, such as paper packaging products, straw, tapioca starch, etc., which is biodegradable and is also called a green and environmentally friendly product; the other is made of plastic as the main component , made by adding ingredients such as tapioca starch and initiators.

1) Biodegradable new stone lunch box

Disposable degradable lunch boxes made of new materials are also called fully biodegradable reusable bento box. The fully biodegradable lunch box is a relatively good green and environmentally friendly product. It uses corn starch as the main raw material, adds annual growth fiber powder, and uses chemical and physical methods to make a fully biodegradable fast food box. Because starch is a biodegradable polymer, it dissolves into glucose water under the action of microorganisms, and finally dissolves into water and carbon dioxide.

 

In addition, the blended raw materials are also fully degradable materials, so it can be said that it does not harm the natural environment. The specific source of raw material starch can be corn, potato, sweet potato, cassava and other annual plants. Of course, biodegradable lunch boxes are not perfect. For example, most of the manufacturing raw materials are crops, and problems such as mildew removal still need to be solved.

 

 

2) Biodegradable plastic lunch box

The raw material for the production of this type of reusable take out containers are degradable plastic. To put it bluntly, degradable plastic means adding a certain amount of additives, such as initiators, starch and other materials, during the plastic production process.

 

In this way, after the biodegradable plastic products are used and discarded and exposed to the environment for three months, they can be transformed from the complete shape into fragments, thus less visually improving the environment. However, the biggest disadvantage of this process is that these fragments cannot be degraded again, but change from large areas to small pieces of plastic, which cannot fulfill the task of removing white garbage from the source.
