 its high temperature resistance is very good, can be used as a kettle shell, baby bottles and other food containers can be used to it.

 However, the high temperature resistance of PET plastic bottles is not as good as that of PP plastic bottles, and the carbonated drinks we usually drink, such as cola, Sprite, 

and some juice packaging plastic bottles are made of it.

Any kind of plastic product has a temperature limit when it is used, if the temperature is too high, it will decompose into a harmful substance, or our plastic is easy to be softened.
