What material is safe for children's plastic cups? What material is safe for children's plastic cups?

1. Cup marked with "PE". "PE" refers to the composition of polyethylene, which is characterized by not being afraid of most acid and alkali corrosion. However, it has a relatively low melting point. Only PE children's cups are 92℃, so polyethylene cups can't be used to hold boiling water. If we fill this cup with boiling water, the cup itself will become very soft. For example, some plastic disposable cups are made of this material. If you use this cup for a long time, it will be harmful to your health. Because boiling water may decompose plastics and produce some harmful substances, which will enter our bodies with water. Therefore, it is not recommended for children to choose PE cups.

2. Cup marked with "PP". "PP" is made of polypropylene, and the glass made of it is crystal clear, beautiful, light and firm. The temperature resistance of this kind of water cup has also been greatly improved. The service temperature is between -30 ~ 140℃, and it can be used for filling hot water or sterilizing at a high temperature above 100℃. Moreover, polypropylene (pp) has a special property, that is, it is the only plastic product that can be heated by microwave oven.

3. Water cups marked with "Tritan". Qutan is also not resistant to high temperature, so it is not recommended to fill it with boiling water. However, one advantage of this kind of water cup is that this material will not produce BPA (bisphenol A) during the synthesis process. Many plastic products contain BPA. Long-term intake of trace BPA may cause children's endocrine system disorder and early puberty. Therefore, this kind of water cup is not recommended for children.

4. Water cup marked "Tritan". Tritan water cups are relatively environmentally friendly and safe. It does not contain BPA, and there are no toxic and harmful substances that affect children's health. In many European and American countries, this is the designated material for baby products, and its safety is relatively guaranteed. Parents can buy them for their children.
