Have you ever used the plastic bottle of the used beverage when the glass is used? Do you know which plastic bottles take hot water and release toxic carcinogens? In fact, each plastic bottle has a small ID card - a triangular symbol, usually at the bottom of the plastic bottle. Inside the triangle there are 1 to 7 numbers, each number represents a plastic bottle, their production of different materials, the use of contraindications are also different.
"1" PET: mineral water bottles, carbonated beverage bottles
Drink bottles do not use hot water cycle
Use: heat to 70 ℃, only suitable for warm drinks or frozen drinks, loaded with high temperature liquid, or easy to deformation when heated, there are harmful substances melt. And, scientists found that No. 1 plastic products with 10 months after the release of carcinogens DEHP may be toxic to the testes.
As a result, bottles and other drinks are discarded when they are used up. They should not be used for drinking cups or other storage containers to avoid causing health problems.
" 2" HDPE: cleaning supplies, bath products
Not cleaned thoroughly recommended not to recycle
Use: Can be repeatedly used after careful cleaning, but these containers are usually not good to clean, leaving the original cleaning products, become a hotbed of bacteria, it is best not to recycle.
" 3" PVC: Currently rarely used in food packaging
It is best not to buy
Use: This material is prone to harmful substances at high temperature, it will be released even in the manufacturing process. Poisons may enter the body with food and cause diseases such as breast cancer and neonatal birth defects. At present, containers of this material have been less used for packaging food. If used, do not let it heat.
"4" LDPE: plastic wrap, plastic film and so on
Cling film wrapped in the food surface into the microwave oven
Use: heat resistance is not strong, usually, qualified PE cling film in case of temperature exceeds 110 ℃ will appear hot melt phenomenon, will leave some of the body can not break down the plastic preparation. And, wrap the food with plastic wrap heating, food grease is easy to dissolve the harmful substances in the plastic wrap out. Therefore, the food into the microwave oven, you must first remove the wrapped plastic wrap.
"5" PP: microwave meal boxes
Remove the lid when in the microwave
Use: The only plastic box that can be placed in the microwave oven for repeated use after careful cleaning. Special attention should be paid to some microwave lunch boxes. The box is indeed made of PP No. 5, but the lid is made of No. 1 PE. Because PE can not withstand high temperatures, 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.
"6" PS: bowl filled instant noodles box, fast food box
Do not cook in a microwave bowl of instant noodles
Use: Also heat-resistant and cold-resistant, but can not be placed in the microwave, so as to avoid the release of chemicals due to high temperature. And can not be used to take a strong acid (such as orange juice), strong alkaline substances, because it will break down on the human body is not good for polystyrene, carcinogenic. Therefore, you should try to avoid using the fast food box packaged hot food.
"7" PC Other categories: water bottles, cups, bottles
PC adhesive heat release bisphenol A
 Use: A widely used material, especially for use in baby bottles, is controversial because it contains BPA. Lin Han-hua, an associate professor of biology and chemistry at City University of Hong Kong, said that in theory, as long as bisphenol A is converted into a plastic structure 100% of the time in the process of making a PC, it means that there is absolutely no bisphenol A in the product, not to mention release. However, if a small amount of bisphenol A is not converted into a plastic structure of PC, it may be released into the food or drink. Therefore, be careful, be careful when using this plastic bottle.
