glass
Glass material is the highest in safety. At present, glass baby bottles on the market are divided into ordinary glass and high borosilicate glass, and high borosilicate glass is superior to ordinary glass in both heat resistance and air permeability.
Advantages: 1 High safety, high heat resistance, and no toxic substances will be released after high temperature disinfection.
2. High permeability, not easy to scratch, and the scale will not be blurred because of long use time.
3. It's not easy to hide evil and accommodate evil, and it's easy to clean.
Disadvantages: 1 Weak and fragile.
2. The bottle is heavy, so it is not recommended for the baby to hold it.
3. It is easy to explode when it expands with heat and contracts with cold.
Recommended brands: Beiqin, Bibi (high borosilicate glass), NUK and avent.
