What are the precautions for using disposable soup cups?

1: It is best not to drink the first cup of water, scald it with boiling water first, and pour out the water after four or five minutes, so that the harmful substances in the disposable soup cup can be fully volatilized. Because phosphors and inks are highly permeable, they will contaminate food.

2: Try not to heat the disposable soup cup or instant noodle carton in the microwave oven.

3: Try not to hold hot water in the disposable soup cup, because some manufacturers apply a thin layer of wax on the disposable soup cup to prevent the water from seeping out, and it will melt when it encounters hot water over 40 degrees. Therefore, disposable soup cups are best used for cold drinks, not hot water above 40°C.
