When we turn over the bottom of the anti-uv pet bottle packaging, we will find that there are different numbers marked on it. Now let's take a look at the meaning of the bottom numbers of anti-uv pet bottle packaging.
The number 1 represents PET(polyethylene terephthalate) :
It is used in general mineral water, carbonated drinks and functional drink bottles. Heat resistance to 70 ° C is easy to deform, so do not put it in the open air or in the car in high temperature weather, and do not directly flush the boiling water into it. Long-term recycling is not recommended, as 10 months of use may release carcinogens.
The number 2 represents HDPE(High density polyethylene) :
It is used to make containers for cleaning supplies. High temperature resistance but not easy to clean, easy to breed bacteria, not recommended for recycling.
The number 3 represents PVC(polyvinyl chloride) :
The toxic and harmful substances that are easy to produce come from two aspects: first, the monomolecular vinyl chloride that is not completely polymerized in the production process; The second is harmful substances in plasticizers. These two substances are easily released when they encounter high temperature and oil, and toxic substances enter the human body with food and are easy to cause cancer.
The number 4 represents LDPE(Low density polyethylene) :
Plastic wrap, plastic film and other use this material, heat resistance is not strong, when the temperature exceeds 110℃ hot melt, remember to take it off before heating in the microwave oven.
The number 5 represents PP(polypropylene) :
The microwave lunch box is made of this material, resistant to 130 ° C high temperature, is the only plastic box that can be put into the microwave oven, and can be reused after cleaning. However, some lunch boxes are made with No. 5 PP, but the lid is made with No. 6 PS(polystyrene), so the lid cannot be put into the microwave oven.
The number 6 represents PS(polystyrene) :
It can not be put into the microwave oven, and can not be used to install strong acids (such as orange juice) and strong alkaline substances, because it will decompose carcinogens such as polystyrene that are harmful to the human body. So don't pack hot food in a fast food box.
The number 7 represents other categories:
It is widely used in the manufacture of baby bottles and space cups. However, because it contains bisphenol A, try not to use it for boiling water.
