Plastic bottles are a necessity in our daily life. How to easily judge the damage of those plastic bottles after use can be said to be a more important skill in our daily life. There are many factors that determine which plastic bottles are harmful to the human body. Today we learn about the healthy use of plastic bottles by knowing the identity of the bottom of plastic bottles.
"No. 1" PET: mineral water bottles, carbonated beverage bottles, etc.
Drink bottles do not use hot water
Use: heat resistant to 70 ° C, only suitable for warm drinks or frozen drinks, high temperature liquid, or heating is easy to deform, there are substances harmful to the human body. Moreover, the scientists found that after 10 months of plastic products, it may release the carcinogen DEHP, which is toxic to the testes. Therefore, if the beverage bottle is used up, it will be discarded. Do not use it as a water cup, or use it as a storage container to take other items, so as not to cause health problems.
"No. 2" HDPE: cleaning products, bath products
It is not recommended to recycle without thorough cleaning.
Use: It can be reused after careful cleaning, but these containers are usually not easy to clean, leaving the original cleaning products and turning into a hotbed of bacteria. You should not recycle them.
“No. 3” PVC: Currently rarely used for food packaging
Best not to buy
Use: This material is prone to harmful substances when it is hot, and even it will be released during the manufacturing process. When toxic substances enter the human body with food, it may cause diseases such as breast cancer and neonatal congenital defects. Currently, containers of this material have been used less for packaged foods. If you are using it, don't let it get hot.
"No. 4" LDPE: plastic wrap, plastic film, etc.
The cling film is wrapped in a microwave oven on the surface of the food.
Use: The heat resistance is not strong. Generally, the qualified PE plastic wrap will have a hot melt phenomenon when the temperature exceeds 110 °C, leaving some plastic preparations that cannot be decomposed by the human body. Moreover, the food is heated by wrapping the plastic wrap, and the fat in the food can easily dissolve the harmful substances in the wrap film. Therefore, when the food is placed in the microwave oven, the wrapped plastic wrap is first removed.
"No. 5" PP: microwave lunch box
Remove the cover when placing it in the microwave
Use: The only plastic case that can be placed in the microwave oven can be reused after careful cleaning. Need special attention, some microwave lunch boxes, the box is indeed made of No. 5 PP, but the cover is made of No. 1 PE, because PE can not withstand high temperature, it can not be put into the microwave together with the box. To be on the safe side, remove the lid before placing the container in the microwave oven.
"No. 6" PS: bowl of instant noodles, fast food box
Don't use microwave oven to cook instant noodles
Use: It is heat-resistant and cold-resistant, but it cannot be placed in a microwave oven to prevent the release of chemicals due to excessive temperature. It can not be used to pack strong acid (such as orange juice) and strong alkaline substances, because it will decompose polystyrene which is not good for the human body and is easy to cause cancer. Therefore, you should try to avoid using hot food boxes to pack hot food.
