In summer, bright-coloured, lovely and light plastic water bottles, which can withstand falling, have become the love of parents. However, in the face of a variety of plastic water bottles, how to choose? The plastic water bottle made of polypropylene (pp) is safer. The bottom of the water cup made of this material is printed with the number "5", which can be heated and disinfected in the microwave oven. When the water bottle made of PC is heated too high, used too long or encounters acidic substances, it is easy to precipitate harmful substances: free phenol. If free phenol is absorbed excessively by human body, it may destroy liver and kidney cells and cause chronic poisoning, which is no less harmful than phenol and formaldehyde. Therefore, it is not recommended to buy and use PC water bottles
So, how to choose a safe plastic water bottle for children in summer? First, we should try to buy it in supermarkets, shopping malls, specialty stores or mother-child chain stores, where the products sold generally have a fixed channel of purchase, and the product quality is relatively reliable. Second, when buying plastic water bottles for children, we should pay attention to the integrity of the information in the label of the product, such as: manufacturers. Implementing standards and materials, try to buy plastic water bottles made of PP or TRITAN. Other materials of children's plastic water bottles are not recommended to use microwave oven for heating and disinfection, so as to avoid releasing substances harmful to human health
In addition, when purchasing plastic water bottles, attention should be paid to the material of bottle caps, pipettes and other parts. Some children's plastic water bottle body is made of PP material, but parts such as bottle cap and straw are made of other materials. Consumers should be able to identify clearly when purchasing.
Of course, when choosing and purchasing, we should not only look at the price, but also pay more attention to the safety performance of goods.
