With the acceleration of the pace of life, paper cups are becoming more and more into people's fast life, and paper cups can be divided into "cold drink cups" and "hot drink cups......
You may think that a paper cup is nothing more than cold water and hot water, what else can be the difference?
According to the material, paper cups can be divided into two types: paraffin cups and PE coated cups:
Paraffin wax is very stable at 0-5 degrees Celsius, but when it reaches 42-62 degrees Celsius, the paraffin wax melts and releases harmful substances such as polycyclic fenfins, which are a possible carcinogen, therefore, paraffin cups should only be used for cold drinks!
PE film is a kind of plastic film, which can be waterproof, can be low temperature, and can also withstand high temperatures of 100 degrees Celsius, so it can be filled with both hot and cold drinks!
