Plastic PES Material - BPA free!

Also called Polyethersulfone, it is not a traditional bottle material because of the relatively high cost of raw materials, very transparent, but the colour is not glass as colourless, but a little bit of brown/honey, some Ma may not like it. However, it is more tolerant than PP and can withstand temperatures above 180 ° C (this is the biggest difference between PES and PP) and can be sterilized repeatedly, with a longer life expectancy than PP.
