What are the main components of degradable disposable lunch boxes?
2023-02-20
There are two kinds of materials used for degradable lunch boxes: one is made of natural materials, such as paper products, straw, starch, etc., which are degradable, also known as environmental protection products; The other is made of plastic as the main ingredient and added with starch, bang sensitizer and other substances.
1. Meal box made of biodegradable materials
The disposable degradable lunch box made of natural bamboo material is also known as the biodegradable lunch box. Biodegradable lunch box is an advanced environmental protection product. It takes starch as the main raw material, adds plant fiber powder and special additives in the one-year growth period, and then makes biodegradable fast food box after chemical and physical treatment. Because starch is a biodegradable macromolecule, it is decomposed into glucose under the action of microorganisms, and then 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 sources of raw material starch can be corn, potato, sweet potato, cassava and other plants with one-year growth period. Naturally, the biodegradable lunch box is not perfect. For example, most of the raw materials are food crops, and there are problems such as mildew prevention that need to be solved.
2. Degradable plastic lunch box
This kind of disposable lunch box is made of degradable plastic. The so-called degradable plastic is to add a certain amount of additives in the plastic production process, such as bang sensitizer, starch and other raw materials. In this way, the degradable plastic products can be decomposed into fragments from the complete shape after being used and discarded in the nature for three months, thus changing the environment visually at least. However, the disadvantage of this technology is that these fragments cannot continue to degrade. They are only changed from larger pieces into small pieces of plastic. They are not fundamentally qualified for the task of removing white pollution.
