"No. 1" PETE

Mineral water bottles, carbonated beverage bottles

Do not recycle or install hot water in beverage bottles. Use: heat resistant to 70 ℃, only suitable for warm or frozen drinks, high temperature liquid, or heating is easy to deformation, there are harmful substances melt out. Moreover, scientists found that after 10 months of use, the No. 1 plastic may release the carcinogen DEHP, which is toxic to the testes.

"No. 2" HDPE

Cleaning products, bath products

Cleaning can not be 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 supplies and becoming a hotbed of bacteria. It is best not to recycle them.

"No. 3" PVC

Rarely used for food packaging, it is best not to buy.

"No. 4" LDPE

Fresh-keeping film, plastic film, etc.

Do not heat food in the microwave with plastic wrap. Use: heat resistance is not strong, usually, qualified PE cling film in the case of temperature more than 110 ℃ will appear hot melt phenomenon, will leave some human body can not decompose the plastic preparation. In addition, the food is heated with plastic wrap, and the fat in the food can easily dissolve the harmful substances in the plastic wrap. Therefore, when food enters the microwave oven, the plastic wrap must be removed first.

"No. 5" PP

Microwave lunch box

When you put it in the microwave oven, you should take the lid off.

Use: The only plastic box that can be put into the microwave oven, which can be reused after careful cleaning. Special attention should be paid to the fact that for some microwave oven lunch boxes, the box body is indeed made of PP No. 5, but the box cover is made of PE No. 1. Since PE cannot withstand high temperatures, it cannot be put into the microwave oven together with the box body. To be on the safe side, remove the lid before the container is placed in the microwave.

"6" PS

Bowl-packed instant noodle box, snack box

Do not use microwave oven to cook instant noodles.

Use: heat and cold, but can not be put in the microwave oven, so as not to release chemicals due to high temperature. And can not be used to contain strong acid (such as orange juice), strong alkaline substances, because it will decompose the human body bad polystyrene, easy to cause cancer. Therefore, you should try to avoid packing hot food in fast food boxes.

"7" PC

Other categories: kettle, cup, bottle

PC glue meets heat release bisphenol A

Use: A material that is heavily used, especially in baby bottles, is controversial because it contains bisphenol A. Lin Hanhua, associate professor of biology and chemistry at City University of Hong Kong, said that in theory, as long as bisphenol A is 100% converted into plastic structure in the process of making PC, it means that the product has no bisphenol A at all, let alone released. However, if a small amount of bisphenol A is not converted into the plastic structure of PC, it may be released into the food or beverage. Therefore, be careful when using this plastic container.

PC residual bisphenol A, the higher the temperature, the release of more, the faster. Therefore, do not use PC water bottles to hold hot water, so as not to increase the rate and concentration of bisphenol A (if any) release. If your kettle has a number 7, the following methods can reduce the risk:

● Wash the kettle without a dishwasher or a bowl dryer.

● Do not heat when using.

● Do not let the kettle in direct sunlight.

● Before first use, wash with baking soda in warm water and dry naturally at room temperature. Because bisphenol A will be released more during the first use and long-term use.

● If the container has any fall or damage, it is recommended to stop using, because the surface of plastic products if there are subtle pits, easy to hide bacteria.

● Avoid repeated use of aging plastic appliances.
