Almost every new parent will be hysterical about bottle safety. However, from a safety point of view, the preferred material is naturally glass. Glass is almost the healthiest tableware material, and almost all first-line bottle-making enterprises use high-quality glass (mainly lead-free high-boron glass), and its physical properties also determine that glass will not release toxic and harmful substances like plastic materials.

For newborns (babies less than 8 months old), Science Parenting Encyclopedia also suggests that Bao's father Ma Bao use big-name genuine glass bottles for the baby. Then, as the baby grows up and is more active, please also use big-name genuine plastic bottles. The reason is: a friend once said, "I bought nine glass bottles, and now there are nine caps left." And almost all the cups after one year old are made of glass. Choosing plastic bottles is a huge topic (even a difficult problem). What brand do you choose? How to tell the truth from the false? Which optional materials are healthier? At present, the mainstream plastic bottles are almost all made of pc (because of the release of polyphenol A, many countries have banned the use as bottle materials. For the sake of children's health, please don't buy bottles made of PC). At present, the mainstream plastic baby bottles are basically PP, PPSU, PES, and soft silicone. None of the above materials contains polyphenol A (provided that the process and purity pass). So what kind of material is good?

Polypropylene bottles are cheaper than PPSU and polyethersulfone. The physical properties of PP are milky white, the atomization is not so transparent, the softness is easier to scratch and wear, and the high temperature resistance is not as good as the latter two. Science parenting encyclopedia is not recommended to buy!

PPSU and PES are new plastic materials. They are amber transparent (much more transparent than PP), harder, less worn, lighter and healthier. Both of them are excellent bottle materials, and their durability and high temperature resistance are obviously superior to those of PP. Compared with them, PPSU is superior to PES in durability and high temperature resistance. On the market, PPSU bottles are mainly made by parents, while PE is mainly from the camp of Dr. Xin Anyi and Dr. Brown (other brands of plastic bottle parenting science books don't mind buying, the price gap is relatively small, and a plastic bottle can last for a long time). So the answer to the question of bottle material selection is: you can choose glass bottles at home, and you can choose plastic bottles or soft silicone bottles made of PPSU or PES when you go out.
