The triangular plastic on the plastic product can be recycled to represent each plastic vessel, with a number at the bottom (it is a triangle with an arrow and a number inside the triangle).
"No. 1" PET
Mineral water bottles, carbonated beverage bottles, pay attention to the careful use of hot water.
Use: heat resistant to 65 ° C, cold to -20 ° 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 carry other items, so as not to cause health problems.
"No. 2" HDPE
Cleaning products, bath products
Cleaning is not thorough, it is recommended not to recycle
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 in 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 birth defects. Currently, containers of this material have been used less for packaging foods. If you are using it, don't let it get hot.
"No. 4" LDPE
Cling film, 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 cling film 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 wrapped in plastic wrap is heated, 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, crisper
Because microwave oven lunch boxes generally use microwave PP (polypropylene, microwave oven special PP high temperature 120 ° C, low temperature -20 ° C), due to cost of production, the cover generally does not use special PP, when placed in the microwave, you need to take the lid below be usable. Since most types of bayonet type crisper boxes use transparent PP instead of special PP, they cannot generally be placed in a microwave oven.
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 PET, because PET can not withstand high temperature, it can not be placed in the microwave oven together with the box. To be on the safe side, remove the lid before placing the container in the microwave oven.
