"07" -- PC and other classes
Common uses: kettles, cups, bottles, and so on
PC is widely used as a material, especially for the manufacture of milk bottles, space cups and so on. It is controversial because it contains bisphenol A. Experts point out that in theory, as long as the bisphenol A is converted to plastic structure 100% in the process of making PC, it is indicated that the product has no bisphenol A, let alone release. However, if a small amount of bisphenol A is not converted into a plastic structure of PC, it may be released into food or drink.
Therefore, when using this plastic container, we must strictly store food according to the instructions, store and sterilize it in the right way, and avoid repeating the aging or damaged PC products.
Bisphenol A residues in PC, the higher the temperature, the faster speed of release. Therefore, hot water should not be filled with PC water bottle.

Avoid the repeated use of ageing plastic utensils.
A cup of low is 7 cups are made of polycarbonate used, namely PC, is used to call a bisphenol A material in the production process of PC material, PC material will be more or less in the presence of bisphenol A monomer, the higher the temperature, the faster speed of release.
General PC plastic cup can be resistant to -30-140 degrees, the physical properties of materials, it is said that this material in this temperature is not cracking and melting, but this is not from the food safety point of view, in the high temperature biphenol A precipitation, is harmful to the body, there is reported that will affect the male sexual function, the use of PC material has been banned in Canada and some western the cups, bottles etc.. It is best not to use a PC glass for hot water during the period of safety, and not to be heated in a microwave oven.
