Use safe plastic products:
In order to ensure our health, we need to choose to use safe plastic products in our daily life. According to Nanjing Daily, when buying plastic drinking cups, consumers should pay attention to whether the information on the product label is complete, including the manufacturer, production license number, implementation standard and material.
Among them, the materials should list in detail all the materials that may come into contact with food, including cup cover, cup body, straw and so on. Experts suggest that plastic food containers, including children's plastic cups, should be made of PP as much as possible.
In addition, consumers should try to avoid using plastic containers or plastic bags to put hot water, hot soup, tea and coffee, and also avoid using microwave ovens to heat food in non-dedicated plastic containers.
