   Disposable plastic tableware safety distinction

   Every plastic product has a triangle with an arrow at the bottom, which is a "recycled" sign. There are Arabic numerals from 1-7, and the difference in Arabic numerals represents the different properties and different uses of this plastic material. It's like the identification of plastic products.

        The number "1" means that the material of the plastic is PET, that is, polyethylene terephthalate, common mineral water bottles, carbonated beverage bottles, etc., heat-resistant to 70°C, easy to deform, and dissolve harmful substances to the human body; use After 10 months, the carcinogen DEHP may be released; it cannot be placed in the car in the sun, and it cannot be filled with alcohol or oil. The bottle with this logo can no longer be filled with water after use, please throw it in the recyclable trash can and let it be recycled.

   The number "2" means that the plastic material is HDPE, which is commonly used as packaging bottles for cleaning products and shower products. Not used for food packaging.

   The number "3" means that the plastic material is PVC. This kind of material is prone to produce harmful substances when it is high temperature, and it will even be released during the manufacturing process. After the toxic substances enter the human body with food, they may cause breast cancer, birth defects and other diseases in newborns. Containers of this material have been rarely used for packaging food. If it is in use, do not let it heat up.

  The number "4" means that the plastic material is LDPE. General products are cling film, plastic film, etc. The heat resistance is not strong. Generally, qualified PE cling film will melt when the temperature exceeds 110 ℃, leaving some plastic preparations that cannot be decomposed by the human body. In addition, when food is wrapped with plastic wrap and heated, the fat in the food can easily dissolve harmful substances in the plastic wrap. Therefore, when food is put into the microwave oven, the wrapped plastic wrap must be removed first.

  The number "5" means that the material of the plastic is PP. High temperature resistance, more common in microwave lunch boxes. Can be reused after careful cleaning. Special attention should be paid to some microwave lunch boxes. The box body is indeed made of No. 5 PP, but the lid is made of No. 1 PE. Because PE cannot withstand high temperatures, it cannot be placed in the microwave together with the box. To be safe, remove the lid before placing the container in the microwave.

   The number "6" represents that the plastic material is PS. It is more common in bowls of instant noodle boxes and fast food boxes. It is heat-resistant and cold-resistant, but it cannot be placed in a microwave oven to avoid the release of chemicals due to excessive temperature. And can not be used to contain strong acids (such as orange juice), strong alkaline substances, because it will decompose polystyrene, which is not good for the human body, and easily cause cancer. Therefore, you should try to avoid using fast food boxes to pack hot food.

   The number "7" represents the plastic material other than PVC and polystyrene or a composite material of multiple plastic materials. More common in water bottles, water cups, and baby bottles. High temperature resistant, can be used repeatedly, but cannot be heated in a microwave oven.
