Mineral water bottle, carbonated beverage bottle
The beverage bottle does not circulate to use the hot water Use: Heat-resistant to 70 ℃, only suitable for warm drink or frozen drink, high temperature liquid, or heating is easy to deform, there is harmful to the body of the material melt out.
And, scientists found that 1th plastic products after 10 months, may release a carcinogen DEHP, the testes are toxic.
"No. 2nd" HDPE
Cleaning supplies, bath products
Clean not thoroughly recommended do not cycle use
Use: can be reused after careful cleaning, but these containers are usually not good cleaning, residue of the original cleaning supplies, become a hotbed of bacteria, you'd better not recycle.
"No. 3rd" PVC
Currently rarely used in food packaging best not to buy
"No. 4th" LDPE
Cling film, plastic film, etc.
Wrap the film on the food surface into the microwave oven Use: Heat resistance is not strong, usually, qualified PE cling film in the temperature of more than 110 ℃ will appear hot melt phenomenon, will leave some human body can not decompose plastic formulations. Also, wrap food with plastic wrap to heat up, the grease in food is easy to dissolve the harmful substance in the cling film.
Therefore, the food into the microwave oven, the first to remove the wrapped cling film.
"No. 5th" PP
Microwave Dining Box

"No. 6th" PS
Bowl bubble Noodle box, fast food box
Don't use the microwave to cook the noodles. Use: Heat and cold, but can not be put into the microwave, so as to avoid the temperature is too high to release the chemical. And can not be used to hold strong acid (such as orange juice), high alkaline substances, because it will break down on the human body is not good polystyrene, easy to cause cancer.
Therefore, you should try to avoid packing hot food with fast food boxes.
"Number 7th" PC
Other types: kettle, water cup, bottle
PC Adhesive Heat Release Bisphenol A Use: A material that is used extensively, especially in bottles, because it contains bisphenol A and is controversial. Lin Hanwa, associate professor of the Department of Biology and Chemistry, City University of Hong Kong, said theoretically, as long as the process of making a PC, bisphenol A hundred percent conversion into a plastic structure, it means that the product is completely free of bisphenol A, not to mention release. However, if a small amount of BPA is not converted into a plastic structure of a PC, it may be released into food or drink.
Be careful, therefore, to pay extra attention when using this plastic container. The residual bisphenol A in the PC, the higher the temperature, the more release, the faster the speed. Therefore, you should not use a PC water bottle to warm up, so as not to increase the speed and concentration of bisphenol A (if any) release.
If your bottle is numbered 7, the following methods can reduce the risk:
No dishwasher, no dishwasher, no washing machine.
Do not heat when using.
Keep the kettle out of direct sunlight. Before first use, use baking soda powder to clean the water and dry it naturally at room temperature.
Because Bisphenol A is released more in the first use and long term use.
If the container has any fall or breakage, it is recommended to discontinue use, because the plastic product surface if there is a subtle pattern, easy to hide bacteria. Avoid repeated use of aging plastic utensils.
