哺乳瓶の材質はどれが良いでしょうか？

1.Glass baby bottles

Glass baby bottles are characterized by safety, BPA-free, high corrosion resistance and thermal insulation. Glass baby bottles have good transparency and wear resistance. But glass baby bottles have two drawbacks: heavy and fragile. Although the glass baby bottle has a certain thickness, it is easy to break when it falls on the ground. At the same time, it should be noted that thermal expansion and cold contraction will cause glass bursting. Glass baby bottles are heavier than plastic baby bottles and silicone baby bottles. It is difficult for baby to hold the bottle firmly.

2.Plastic baby bottle

Plastic baby bottles include PC bottles, PP bottles, PES bottles, PPSU bottles and so on. PC material has become the most popular material in plastic baby feeding bottles because of its low price, good heat resistance and light quality. However, since the news that BPA is harmful to baby's health appeared in PC bottles, PC can no longer be used as the material of baby feeding bottles.

PP, PES and PPSU baby bottles have their own advantages and disadvantages. At present, PP baby bottles have become the most choice material for consumers in plastic baby feeding bottles because of their low price and good performance.

3. Silicone baby bottle

Silicone baby bottles are made of liquid silicone (LSR), BPA free, non-fragmentation, soft texture, and are very popular with parents. Silicone baby bottles are characterized by good stability and good elasticity at – 60 – 200 C. In addition, the silicone baby bottle has good chemical resistance, acid and alkali resistance, even if any disinfection method is used, it is not easy to deform, and does not contain any harmful substances.
