Plastic No. 1 (PETE)
Common uses: mineral water bottles, carbonated beverage bottles, etc.
The transparent plastic bottle made from it is often called "Pote bottle". This plastic will be deformed when it is heat-resistant to 70°C, so it is only suitable for warm or cold drinks. If it is filled with high-temperature liquid or heated, it is easy to deform and release substances harmful to the human body. The study also found that this plastic product will release carcinogens after 10 months of continuous use, which is extremely harmful to the human body.
Summary: When the beverage bottle is used up, throw it into the "recyclable" trash, and don't use it as a water cup. Avoid heat (such as in a car or back box), avoid cracks (which will release harmful substances); and try not to make storage containers for other items, so as not to cause health problems.
Plastic No. 2 (HDPE)
Common uses: cleaning supplies, bath products, etc.
The packaging of common white medicine bottles, skin care and bath products are all made of this kind of plastic. If you want to reuse it, you need to clean it thoroughly before using it. The trouble is that these containers are usually not easy to clean, and will leave the original cleaning supplies, which can easily become a breeding ground for bacteria, so it is better to be careful!
Summary: It is best not to recycle. Need to be sorted and recycled.
Plastic No. 3 (PVC)
Common uses: raincoats, building materials, etc.
Good plasticity and low price; food cannot be packaged. This material is prone to produce harmful substances when exposed to high temperatures, and even releases toxic substances during the manufacturing process.
Summary: Do not let it heat up when using it.
Plastic No. 4 (LDPE)
Common uses: plastic wrap, etc.
People are accustomed to putting food covered with plastic wrap into a microwave oven to heat, and think that the water in the food is not easy to lose and the food tastes better. But in fact, even qualified PE cling film will melt when the temperature exceeds 110°C. In addition, when the food is wrapped with plastic wrap for heating, the fat in the food can easily dissolve the harmful substances in the plastic wrap. Therefore, it is best to remove the wrapped plastic wrap before putting the food in the microwave.
Summary: It is best not to heat in the microwave.
Plastic No. 5 (PP)
Common use: special lunch box for microwave oven
This is the only plastic box that can be put in a microwave oven and can be reused after thorough cleaning. It is important to note that in some microwave lunch boxes, the box body is indeed made of No. 5 PP, but the lid is made of other grades of plastic. Because the lid is often unable to withstand high temperatures, it cannot be placed together with the box body. Into the microwave.
Summary: To be on the safe side, remove the lid of the container before putting it in the microwave.
Plastic No. 6 (PS)
Common use: bowl of instant noodle box, fast food box
When exposed to high temperature, it will release chemicals that are harmful to the human body; at the same time, it cannot be used to contain acids (such as juice) and alkaline substances because it will decompose carcinogens. Therefore, you should try to avoid using fast food boxes to pack hot food, and do not use microwave ovens to cook bowls of instant noodles.
Summary: Out of considerations for ourselves and the environment, we still have to take a cautious attitude towards such disposable items.
Plastic No. 7 (PC)
Common uses: water bottle, water cup, milk bottle
PC is a material that is used in large quantities, especially in the manufacture of milk bottles, water bottles, etc. The raw material of PC is controversial because it may contain a substance called "bisphenol A". In theory, as long as the bisphenol A is completely converted into a plastic structure in the process of making PC, it means that the product does not contain bisphenol A. However, if a small amount of bisphenol A is not converted into a PC plastic structure, it may be released. If it enters food or drink, it will have a bad effect on the human body.
Summary: It is necessary to store food in strict accordance with the instructions; use the correct method to store and disinfect; avoid repeated use of aging or damaged PC products.
For long-term use or to contain food and beverages, it is better to use ceramic, metal or glass containers as much as possible. This will not only reduce the harm to the human body, but also reduce the use of petrochemical products and make the environment better. good.
