Although disposable plastic lunch boxes are convenient, most of them are low-priced and inferior lunch boxes, even recycled plastic lunch boxes. These unqualified lunch boxes contain industrial calcium carbonate residue, heavy metals, paraffin, benzene and other toxic substances, which seriously endanger human health.

Once the plastic components of inferior disposable plastic lunch boxes encounter high temperature, high oil and ethyl acetate, it is easy to transfer toxic substances into food. Therefore, the use of disposable plastic lunch boxes should be reduced or avoided. The raw materials of foamed plastic lunch boxes contain harmful substances. Once the high-temperature and high-oil food is filled, the harmful substances in foamed plastics can easily precipitate, migrate and condense on the food, and then enter the human body with the food, causing harm to the human body. ?
