However, it should be noted that the state has no mandatory requirement that the bottom of the cup must be marked with material, so some small manufacturers or poor manufacturers will not mark the material of the cup, and most regular manufacturers will mark the material composition at the bottom of the cup.

Therefore, the purchase of plastic cups is the same as the purchase of stainless steel insulated cups. You must go to the regular shopping malls or sales stores to buy them. Don't buy them at roadside stalls.

Every time we buy a cup, we should directly contact with drinking water. If we carry harmful substances, they will harm our health. So we should be careful when buying cups.

In addition to cups, some baby bottles are also made of plastic. Parents also need to pay attention to the material when purchasing. Children should focus on safety.

Summary:

No matter what kind of cups you use, you should be careful when buying. The cup material will directly affect the safety of our drinking water and our health, so you should be careful.
