We need to pay attention to the following issues when purchasing and using paper cups:
1. When purchasing disposable paper cups, look for the QS logo. In addition, you should carefully check whether the product name, factory name, factory address, product execution standards, production date, etc. are marked on the packaging. If the labeling is incomplete or irregular, it is best not to buy such paper cups.
2. Different uses: distinguish between cold drink cups and hot drink cups.
3. Look at the appearance: You should choose products with lighter printing colors. If the paper cup has an obvious smell of ink, it is best not to use it because the ink contains substances harmful to the body.
4. Distinguish the color: Some cups use food-grade base paper on the surface, but use recycled paper, cardboard paper, etc. as the middle layer. It is recommended to tear it open to see if the broken surface is yellow or contains more impurities. If the paper product is too white or contains impurities, it is recommended not to use it.
5. Smell: If the paper cup smells pungent, it may be because the recycled polyethylene undergoes cracking changes during reprocessing. Many compounds volatilize when exposed to high temperatures and easily migrate to water, which will cause harm to human health. to affect, do not use.
