The role of plastic products in our lives is too important. In our lives, we often use plastic cups, beverage bottles, and various plastic wrap bags, etc. These are all made of plastic, which can be said to cover our daily life. Life, and recently many voices are very worried when it comes to plastics, and worry that plastics are poisonous. In fact, many plastics are not poisonous after they are made, because some operations, such as high temperature and long-term heating, cause plastics to produce certain toxic substances. In fact, Fuhe packaging is also a disposable lunch box, as long as you use it, pay attention The properties of some plastics, safe use, are basically no problem.

　　 I have talked a lot about PP plastic materials before, so let me talk about PET and PE plastic products.

PET is polyethylene terephthalate, and its code name in plastic is "1". This plastic material is mostly used in mineral water bottles and beverage bottles, and we have come into contact with a wide range. When using this kind of plastic products, it is best not to use it to hold high-temperature things, let alone to heat it, and it is best not to use this kind of plastic for disinfection. Once used for a long time, it will easily lead to the growth of bacteria and affect health. For health considerations, it is best not to use it for a long time.

　　PE is a No. 2 plastic polyethylene, which is mostly used in various cling films and various insurance bags, and is a commonly used plastic product in the home. This material is composed of hydrocarbons and does not contain benzene rings. It is no problem to use in low or normal temperature environments. If it encounters high temperatures or oily substances, it is more dangerous and may melt and release toxic substances.

In summary, in fact, many plastic products are not problematic. As long as the properties of plastics are mastered, there is no problem in using them. Once they exceed the scope of their use, they may be dangerous. Safe use is very important.
