According to experts, PC plastic products will release bisphenol A in the encounter of high temperature, and the space cup is the most problematic PC plastic bottle, many people are used to using space cups to make tea, the temperature is too high, bisphenol A is easy to be released, as for drinking buckets, mineral water barrels, mineral water bottles and other plastic products used at room temperature do not worry, These drinking bottles generally do not require BPA, and most are used at room temperature. Too transparent mineral water bottles should also pay attention to, it is likely to contain bisphenol A, if the mineral water bottles are as transparent as glass, it is necessary to pay attention.

Experts remind that some transparent soy milk machine material is also PC material, may contain bisphenol A, some soy milk machine can still be cooked, the release is relatively large. So it is recommended to use stainless steel soy milk machine. As for plastic lunch boxes, chopsticks, spoons and other products, generally do not contain BPA. There is A coating on the inner layer of the metal can, which also uses bisphenol A, so the metal can can not be heated directly, but should be eaten at room temperature, or the contents of the can can be poured out to heat.

The residual bisphenol A in PC plastic products, the higher the temperature, the more the release, the faster the speed. Therefore, hot water should not be held in A PC water bottle to avoid increasing the speed and concentration of BPA release. Experts say that if parents have purchased plastic items numbered 7 for their children or themselves, they can wash them with baking soda and warm water before using them for the first time and dry them naturally at room temperature. Because bisphenol A will be released more during the first use and long-term use. After that, do not heat when in use, do not wash in dishwasher, dish dryer, and do not be in direct sunlight.
