What kind of custom paper coffee cup is safe?

Pick

When choosing a custom paper coffee cup, don't just look at the color of the paper cup, and don't think that the whiter the color, the more hygienic it is. Some paper cup manufacturers add a lot of fluorescent whitening agents to make the cup look whiter. Once these harmful substances enter the human body, they will become potential carcinogens.

Experts suggest that citizens should take a photo under the light when choosing a custom paper coffee cup. If the paper cup appears blue under the gorge light, it proves that the fluorescent agent exceeds the standard, and consumers should use it with caution.

Pinch: the body of the cup is soft and not firm, be careful of water leakage

In addition, it is necessary to choose paper cups with thick and stiff walls. Paper cups with poor cup body stiffness are very soft to pinch. After pouring water or beverages, they will be seriously deformed or even unable to be lifted, which affects the use. When citizens choose paper cups, they can use their hands to gently squeeze on both sides of the cup to roughly know the stiffness of the cup body.

Experts pointed out that the general high-quality paper cups can hold water for 72 hours without leakage, while the poor quality will seep water for half an hour.

Smell: the color of the cup wall is fancy, be careful of ink poisoning

Quality supervision experts pointed out that paper cups are mostly stacked together. If they are damp or contaminated, mold will inevitably form, so damp paper cups must not be used.
In addition, 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 on the outside. The ink contains benzene and toluene, which are harmful to health. It is good to buy paper cups with no ink on the outer layer or less printing.
You can easily tell by smelling it before purchasing and using it.
