Notes On Paper Cups

1： It is best not to drink the first glass of water. First, scald it with boiling water, and after four or five minutes, pour out the water to allow harmful substances in the paper cup to fully evaporate. Because fluorescent powder and ink have strong permeability, they can contaminate food.
2： Disposable paper cups or instant noodle boxes should not be heated in the microwave as much as possible.
3： Try not to fill paper cups with hot water, as some manufacturers apply a thin layer of wax to prevent water from seeping out. When encountering hot water above 40 degrees, it will melt off. Therefore, disposable paper cups are best used to hold cold drinks, rather than hot water above 40 ℃.
