Careful friends will find that most plastic bottles will have numbers and some simple patterns on them, so what do these numbers represent?
“01″: It is best to throw it away after drinking, heat-resistant to 70°C. Commonly used in bottled beverages such as mineral water and carbonated beverages. It cannot be filled with hot water and is only suitable for warm or frozen beverages. High-temperature liquids or heating will easily deform and even dissolve substances that are harmful to the human body.
“02″: It is not recommended to be used as a water container, and the heat resistance is 110°C. Commonly found on plastic containers containing cleaning products, bath products, or plastic bags commonly used in shopping malls. It can withstand high temperature of 110°C, and can be used to hold food if it is marked for food.
“03″: can not be heated, heat-resistant 81 ℃. Common in raincoats and plastic films. Plastic products of this material are prone to produce two toxic and harmful substances, one is the monomolecular vinyl chloride that is not fully polymerized during the production process, and the other is the harmful substances in the plasticizer. These two substances are easy to be precipitated when encountering high temperature and grease, and if they accidentally enter the human body, they are likely to cause cancer. Therefore, it is rarely used for cup production. If you buy a plastic cup of this material, please do not let it heat up.
“04″: Over 110°C, there will be hot-melt phenomenon. Heat-resistant, 110°C. Commonly used in the packaging of cling film and plastic film, the heat resistance is not strong. When the temperature exceeds 110 ℃, the qualified plastic wrap will appear hot melting, leaving some plastic preparations that cannot be decomposed by the human body. If it is wrapped outside the food and heated at the same time, the fat in the food is more likely to dissolve the harmful substances in the plastic wrap.
