The disposable environment-friendly lunch box made from corn starch is non-toxic, harmless, and pollution-free, improving the packaging level of takeaway food, making it easy to use and not easy to spill. Using corn starch based environmentally friendly lunch boxes can greatly save forest resources. Corn starch based environmentally friendly lunch boxes can to some extent replace plastic lunch boxes, reducing white pollution to the environment. It is an ideal substitute for the widely used but controversial "sterilized tableware" in the catering market.

Corn starch based products are environmentally friendly and biodegradable, truly pollution-free and resource saving. Degradable corn starch material, mainly a starch raw material extracted from corn, is an environmentally friendly material that can be naturally biodegradable through microorganisms and enzymes in the natural environment, which is environmentally friendly and odorless, making it safer to use. The product is buried in the soil and can be degraded to form carbon dioxide and water after 90 days at a suitable temperature. It does not cause pollution to the soil and air, and can save a lot of oil and forest resources.
The lunch box has the characteristics of heat and cold resistance, as well as anti extrusion, water resistance, oil resistance, and penetration resistance. After scientific experiments, the lunch box has good resistance to high and low temperatures (- 18120 ℃). It can be frozen, refrigerated, and kept fresh in a refrigerator, and can be heated in a microwave oven. Many methods of use do not produce harmful substances.

Corn starch based tableware is a relatively common biodegradable lunch box in the current market. The main source of starch is corn, so it is sometimes called corn starch based. However, this type of lunch box is actually a mixture of starch and traditional petroleum based PP plastics, which is called biological based abroad. Corn starch based tableware is biodegradable through starch, resulting in the collapse of the physical properties of the entire material. However, the collapsed petroleum based PP is still non degradable, and the degradation rate can reach 40% to 80% based on the composition of the lunch box, so it can only be considered a degradable lunch box, not a fully degradable lunch box. Therefore, corn starch based tableware can only replace plastic products to a certain extent, and is a controversial alternative to plastic tableware in the current market.
