Can plastic bottles hold boiling water?

Can plastic bottles hold boiling water? Please look at the logo and Arabic numerals above. A triangle of three arrows means "recyclable". The numbers in it represent different materials. If the product is made of several different materials, indicate the main material of the product. These figures do not directly represent the heat resistance of plastic bottles, but if we can understand the materials represented by each figure, it will also facilitate consumers to use plastic products more scientifically:

1 stands for PET (polyethylene terephthalate), which is used for general mineral water, carbonated drinks and functional drink bottles. It is easy to deform when the temperature is high, and some harmful substances may be dissolved. Don't put mineral water in the open air or in the car in hot weather, and don't flush boiling water directly into the coke bottle;

2 stands for HDPE (high density polyethylene), which was widely used in plastic bags in supermarkets and shopping malls. High temperature resistance, but not easy to clean, easy to breed bacteria.

3 stands for PVC (polyvinyl chloride), in which plasticizer contains harmful substances, and it is easy to precipitate when it meets high temperature and grease. At present, many plasticizers have been banned in Europe, and plastic products used for packaging food are rarely used in China;

4 stands for LDPE (low density polyethylene). At present, the plastic wrap and plastic film on the market are mostly made of this material, and the heat resistance is not strong. When the temperature of qualified PE plastic wrap exceeds 1 10℃, hot melting will occur. When food is wrapped in plastic wrap and heated, the oil in food will easily dissolve the harmful substances in plastic wrap.

5 stands for PP (polypropylene) The microwave lunch box is made of this material, which can withstand the high temperature of 130℃ and has poor transparency. Some lunch boxes are made of PP, but the lid is made of PS (polystyrene), which has good transparency, but it is not resistant to high temperature, so it can't be put into the microwave oven with the box.

6 stands for PS (polystyrene), which is used to make instant noodle boxes in bowls and foamed fast food boxes. Heat and cold resistance, but it can't be put in the microwave oven. Try to avoid packing hot food in fast food boxes.

7 stands for other categories, such as plastics used to make bottles and space cups. Try not to use it for boiling water.
