Bottom identification
Folding No. 1 PET
Mineral water bottle, carbonated beverage bottle
Drink bottles are looped with hot water
Use: heat -resistant to 70 ° C, only suitable for warm drinks or freezing drinks, high temperature liquid, or heating is easy to deform, and it is harmful to the human body. In addition, scientists have found that after 10 months of plastic products, the carcinogen may be released, which is toxic for testicles.
Therefore, the beverage bottle is thrown out after using it. Do not use it to make A as a water cup, or use it for storage container to install other items, so as not to cause health problems.
Folding No. 2 HDPE (high -density polyethylene)
Cleaning supplies, bathing products
It is recommended not to recycling
Use: You can use it carefully after careful cleaning, but these containers are usually not easy to clean. The original cleaning supplies are left to become a breedingbed of bacteria. You'd better not use it circularly.
Folding No. 3 PVC (Polyvinyl chloride)
It is rarely used for food packaging, it is best not to buy
Folding No. 4 LDPE (low -density polyethylene)
Cling, plastic film, etc.
Do not wrap the plastic wrap on the surface of the food on the microwave oven
Use: The heat resistance is not strong. Generally, the qualified PE plastic wrap will appear hot -melt when the temperature exceeds 110 ° C, leaving some plastic preparations that the human body cannot decompose. In addition, if the food is wrapped with plastic wrap, the oil in the food can easily dissolve the harmful substances in the plastic wrap. Therefore, when the food is entered into a microwave oven, the parceling of plastic wrap must be removed first.
Folding No. 5 PP (polypropylene)
Microwave lunch box
When put in the microwave oven, remove the lid and remove
Use: The only plastic box that can be placed in the microwave oven can be reused after careful cleaning. It is necessary to pay special attention to some microwave lunch boxes, the box body is indeed made of No. 5 PP, but the lid is made of No. 1 PE. Because PE cannot resist the high temperature, it cannot be put in the microwave oven with the box body. For the sake of insurance, the container is put off in front of the microwave oven, first remove the lid.
Folding No. 6 PS (polystyrene)
Bowl foam box, fast food box
Do not use a microwave oven to boil bowl instant noodles
Use: heat resistance and cold resistance, but it cannot be placed in a microwave oven to avoid release of chemicals due to high temperature. And it cannot be used for multiplied strong acids (such as orange juice) and strong alkaline substances, because it will decompose polystyrene that is not good for the human body, which is easy to cause cancer. Therefore, you should try to avoid packing hot food for fast food boxes.
Folding No. 7 PC (polycarbonate)
Other categories: kettle, water cup, bottle
Folding PC glue heat release bisphenol A
Use: A large amount of materials, especially in the bottle, are controversial because they contain bisphenol A. Lin Hanhua, an associate professor of the Department of Biology and Chemistry, Hong Kong University, said that theoretically, as long as the PC is made, bisphenol A is 100 % transformed into a plastic structure, and it means that the product has no bisphenol A at all, let alone release. However, if there is a small amount of bisphenol A that is not converted into a PC, it may be released and enter the food or drink. Therefore, be careful, pay special attention when using this plastic container.
Cleaning bisphenol A
The bisphenol A remaining in the PC, the higher the temperature, the more release, and the faster the speed. Therefore, the PC water bottle should not be filled with hot water, so as not to increase the speed and concentration of bisphenol A (in case). If your kettle has a number 7, the following method can reduce the risk:
Do not heat it during use.
Wash the kettle without dishwasher and dishwasher.
Do not let the kettle shine directly in the sun.
Before using it for the first time, clean it with soda powder and warm water to dry it naturally in room temperature. Because bisphenol A will release more when used and long -term use.
If the container has any injury or damage, it is recommended to stop using it, because if there is a slight pits on the surface of the plastic product, it is easy to hide bacteria.
Avoid repeatedly used plastic appliances.
