PET: mineral water bottle, carbonated drink bottle
Don't recycle the hot water in the drink bottle
Use: heat-resistant to 70 degrees centigrade, only suitable for warm drink or frozen drink, high temperature liquid, or heating is easy to deform, there are harmful substances to the human body melt out. And, scientists have found that the 1 plastic, after 10 months, may release the carcinogen DEHP, which is toxic to the testicles.
Therefore, if the beverage bottle is used up, it will be thrown away, and no longer used as a water cup or as a storage container for other items, so as not to cause health problems.
HDPE: cleaning products, bath products
Do not clean up thoroughly and do not recycle
Use: it can be used repeatedly after being careful and clean, but these containers are usually not well cleaned, leaving the original cleaning products to become a hotbed for bacteria. You'd better not recycle.
PVC: it is rarely used for food packaging at present
It's better not to buy
Use: this material is prone to produce harmful substances at high temperature. Even during the manufacturing process, it will release. Toxic substances will enter the body after food, which may cause breast cancer, neonatal congenital defects and other diseases. At present, the containers of this material have been less used for packaging. If you are in use, do not let it be hot.
LDPE: preservative film, plastic film, etc.
The fresh-keeping film does not pack the microwave oven on the food surface
Use: heat resistance is not strong. Usually, qualified PE fresh-keeping film will appear hot melting phenomenon when the temperature exceeds 110 degrees. It will leave some plastic preparations that human body can't decompose. In addition, it is heated by wrapping the food with a fresh-keeping film. The oil in the food is easy to dissolve the harmful substances in the fresh-keeping film. Therefore, the food into the microwave oven, first to take off the wrapped plastic film.
PP: a microwave oven box
When you put it in the microwave, take the lid off
Use: the only plastic box that can be put into the microwave oven, and can be reused after careful cleaning. We need to pay special attention to the fact that some microwave oven boxes are made of No. 5 PP, but the lid is made of No. 1 PE. Because PE can't withstand high temperature, it can't be put into the microwave oven with the box. For insurance, the container is put in front of the microwave oven and the lid is taken off first.
PS: a bowl of noodle box, fast food box
Don't cook a bowl of instant noodles in a microwave oven
Use: heat resistant and cold resistant, but can not be put into a microwave oven so as not to release chemicals because of the high temperature. And can not be used in heavy acid (such as Liu Chengzhi), strong alkaline substances, because the decomposition of the human body is not good polystyrene, easily carcinogenic. So, you should try to avoid packing hot food in a fast food box.
PC other classes: kettles, cups, bottles
PC TL bisphenol A
Use: a material used in large quantities, especially in bottles, which is controversial because of the inclusion of bisphenol A. Lin Hanhua, an associate professor of biology and chemistry at City University Hong Kong, said that in theory, only when bisphenol A was converted into plastic structure in the process of making PC, it would be indicated that products had no bisphenol A, let alone release. However, if a small amount of bisphenol A is not converted into a plastic structure of PC, it may be released into food or drink. Therefore, be careful, pay extra attention to the use of this plastic container.
