How to choose a safe plastic water cup?

1. Confirm the type of plastic:

The first step is to confirm the plastic type of the cup. On the bottom of the product or on the package, there is usually a triangle symbol with some numbers inside, and these numbers represent the type of plastic of the cup.

For example, the number "5" means that the cup is made of PP (polypropylene), which is a safer material. When choosing plastic cups, you should give priority to the products labeled "5".

2, choose odorless products:

High-quality plastic cups in the production process will not add too much plasticizer, so basically tasteless. If the cup is found in the purchase of a very heavy plastic flavor or chemical flavor, then this may be too much plasticizer performance, so the cup is not suitable for water or food.

3, pay attention to the transparency of the cup:

Generally speaking, the transparency of the plastic cup is high, and can see the inside of the cup, which is conducive to our observation of the state of the drink or food inside the cup when we use it. If the color of the cup is too dark, or the transparency is too low, you should try to avoid choosing.

4, check the surface of the cup:

A high-quality plastic water cup, the surface of the cup should be smooth, without obvious scratches, pits or raised bubble points. These are a direct reflection of the quality of the cup.
