For example, disposable lunch boxes, fresh-keeping bags, disposable paper cups, etc., are usually used directly without washing. Is this true?
Toxic tableware is flooding the market, and disposable tableware such as chopsticks and lunch boxes can be seen everywhere in our lives. Most of the tableware used in some low-end dining places such as street food bars, food stalls, and fast food restaurants are disposable. A large amount of such garbage is "received" in the trash cans in various office buildings and most office spaces every day.
According to regulations, the main raw material for producing lunch boxes is polypropylene, with a content of about 80%; industrial calcium carbonate is used as a filler, and the content cannot exceed 20%. Polypropylene has strong plasticity, and the lunch boxes produced are very strong and not easy to deform. However, industrial calcium carbonate is a kind of stone powder with poor plasticity. It is difficult for the powder to stick together when used in excess. Therefore, the produced lunch boxes are prone to quality problems such as softening and leakage.
The common characteristics of these substandard disposable lunch boxes are that they feel soft to the touch, break easily when torn, and have a peculiar smell. The soft feel makes the lunch box very inconvenient to use, and may even cause food or soup to spill out during meals; and the smell is an obvious sign that the materials used to make the lunch box contain toxic substances.
