There are many materials of plastic water bottle. I don't know if you have found that there are triangle marks at the bottom of the plastic water bottle. These marks represent the material of the plastic water bottle, that is, the ID card of the plastic water bottle. What kind of plastic water bottle is suitable for students? We will discuss this topic and hope you can participate in our discussion.
The plastic water bottle used by students should be safe and healthy. Here we recommend several plastic water bottles to see if they are suitable for students.
Most of the plastic water bottles on the market are made of PP and PC. PP is polypropylene, which has a heat resistance of over 120 ℃, which is relatively safe. PP is polypropylene plastic, non-toxic and tasteless. It can be soaked in boiling water at 100 ℃ without deformation and damage. The common organic solvents of acid and alkali can hardly work on it. At the same time, the plastic water bottle made of food grade PP (polypropylene) material is not easy to decompose in general, and its temperature resistance is mostly higher than PP melting temperature, which is non-toxic to human body as microwave oven appliance in daily use. So the plastic water bottle made of this material is the safest for students.
The bisphenol A (BPA) in the structure of PC material will be dissociated because of high temperature. This ingredient is harmful, so it was banned many years ago. This kind of water bottle can hold cold water.
The last is Tritan plastic water bottle, which does not contain BPA, so tritan plastic water bottle is also very healthy and safe.
