How to distinguish between good and bad paper cups:
Look: the light is blue, be careful with the phosphor
Don't think that the whiter the color, the more hygienic it is. In order to make the cup look whiter, some paper cup manufacturers add a large amount of fluorescent whitening agent. When people choose paper cups, they should take a photo under the lamp. If the paper cup is blue under the fluorescent lamp, it proves that the fluorescent agent exceeds the standard.
Smell: the color of the cup wall is fancy, be careful of ink poisoning
Some paper cups will be printed with colorful patterns and words. When the paper cups are stacked together, the ink on the outside of the paper cup will inevitably affect the inner layer of the paper cup wrapped around it. The ink contains benzene and toluene, which are harmful to health. Paper cups with no ink printing or less printing on the layer.
Pinch: the cup is soft and not firm, be careful of water leakage
Use paper cups with thick and stiff walls. Paper cups with poor body stiffness are very soft when pinched. After pouring water or beverages, they will be severely deformed when held up, or even unable to be held up, which affects the use.
Use: cold cup, hot cup, each has its own role
