The difference of PP PE PET material

PET polyethylene terephthalate is commonly found in mineral water bottles and carbonated beverage bottles. When the temperature reaches 70℃, it is easy to deform, and some harmful substances are melted. No. 1 plastic product may release carcinogen DEHP after 10 months of use. This kind of bottle cannot be placed in the car to bask in the sun, nor can it contain alcohol, oil and other substances.

PE polyethylene is common in plastic wrap and plastic film. Hazardous substances are produced at high temperatures. After the toxic substances enter the human body with food, they may cause diseases such as breast cancer and birth defects of newborns.

PP polypropylene is commonly found in soy milk bottles, yogurt bottles, and microwave lunch boxes. It has a melting point of up to 167°C. It is the only plastic product that can be placed in a microwave oven and can be reused after careful cleaning. It should be noted that some microwave lunch boxes, the box body is made of No. 5 PP, but the lid is made of No. 1 PET. Since PET cannot withstand high temperatures, it cannot be placed in the microwave together with the box.
