In addition to looking at the signs above to understand the functions of the products, we should also distinguish the quality of plastic materials. For example, the lunch box is very soft, if pressed, it will have fingerprints, if torn by hand, it will break, or if put in water, it will sink, which means that there are impurities in the lunch box, and industrial waste plastics are probably added. This kind of lunch box must not be heated by microwave, even if it is hot (above 70℃).
In addition, it should be noted that the darker the color, the more impurities there are in the lunch box, and manufacturers often cover up the impurities by adding colors. The wholesale price of some all-black lunch boxes is only 10 cents, and about half of them are impurities. The box is hard and brittle, and it sags and deforms when heated. In addition, plastic lunch boxes will be cut into pieces and put into water, and more impurities will sink, while high-quality ones will float on the water.
Note: Check the labels on plastic lunch boxes containing information such as materials and usage methods, and use plastic lunch boxes correctly. Avoid letting unsafe factors affect health.
