Tips for choosing a paper bowl

First of all, we can see whether the identification information on the package is complete, whether the production license number and QS logo are marked, etc. At the same time, it is necessary to look at the color of the paper cup, not too bright. The paper cup is pointed at the light, and there are no impurities. If the paper cup appears blue under a fluorescent light, it is a sign that the fluorescent agent may be exceeded. At the same time, it is also necessary to pay attention to whether the paper cup is produced in accordance with the new national standard, and try to choose products marked with GB/T27590 standard.
Secondly, we can use our hands to gently squeeze on both sides of the cup, and we can roughly know the quality of the cup. If it is a high-quality paper cup, it is harder and has a certain resilience, while a low-quality paper cup is softer after pinching, has no resilience, and is easy to pinch flat. Generally, high-quality paper cups can be filled with water for 72 hours without leakage, while poor quality will seep water in half an hour.

Preferably, we can also smell the paper cup for pungent odors, especially the smell of ink, or the smell of mold. Because generally qualified paper bowls do not smell too heavy and pungent, on the contrary, which inferior paper bowls will have a strong taste or a direct moldy smell.
