1. Degradable natural material lunch box

The disposable degradable lunch box made of natural materials is also called biological fully degradable lunch box. Biodegradable lunch box is an advanced environmental protection product. It takes starch as the main raw material, adds one-year plant fiber powder and special additives, and is processed by chemical and physical methods to make a biodegradable fast food box.

As starch is a biodegradable natural polymer, it is decomposed into glucose, water and carbon dioxide under the action of microorganisms. 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 starch can be plants in one-year growth period such as corn, potato, sweet potato and cassava. Naturally, biodegradable lunch boxes are not perfect. For example, most of the production raw materials are food crops, and problems such as mildew prevention have yet to be solved.

2. Degradable plastic lunch box

The raw material of this kind of disposable lunch box is degradable plastic. The so-called degradable plastic is to add a certain amount of additives in the production process of plastic, such as photosensitizer, starch and other raw materials. In this way, the degradable plastic products can be decomposed into fragments from the complete shape after being used, discarded and exposed in nature for three months, thus improving the environment at least visually

However, the biggest defect of this technology is that these fragments can not continue to degrade. They just change from large pieces to small pieces of plastic, which is not fundamentally competent for the task of eliminating white pollution.
