Safety appraisal of plastic foam bottles and plastic containers
Plastic packaging suitable for food or plastic bottles for beverages and water are made of a few types of plastics, and their use conditions are restricted. For the sake of health, how to use plastic plastic bottles rationally?
The plastic packaging used for beverage products is generally a PET plastic bottle, which heats up to 70°C. It is only suitable for warm or frozen drinks. It is easy to deform when it is filled with high-temperature liquid or heated, and harmful substances to the human body will melt. Therefore, throw away the beverage bottle when it is used up, and don't use it as a water cup, or as a storage container for other items, so as not to cause health problems.
The PC material plastic is generally used to make water bottles, water cups, and baby bottles. The safety performance of PC in baby bottles is currently controversial because it contains bisphenol A. Many foreign countries such as Canada have banned baby bottles containing bisphenol A. In theory, as long as 100% of the bisphenol A is converted into a plastic structure in the process of making PC, it means that the product is completely free of bisphenol A, let alone released. However, if a small amount of bisphenol A is not converted into the plastic structure of PC, it may be released into food or drink. Therefore, be careful, and pay extra attention when using this plastic container. The residual bisphenol A in PC, the higher the temperature, the more release and the faster the speed. Therefore, the PC water bottle should not be used to hold hot water, so as not to increase the release rate and concentration of bisphenol A (if any).
For people’s favorite bowls of instant noodle boxes and fast food boxes, because they contain PS, although they are heat-resistant and cold-resistant, they cannot be placed in a microwave oven to avoid the release of chemicals due to high temperatures. I like to cook instant noodles in a microwave oven. Please pay attention to your friends. And can't be used to carry strong acids (such as orange juice), strong alkaline substances, because it will decompose polystyrene, which is not good for the human body, and is easy to cause cancer. Therefore, try to avoid using fast food boxes to pack hot food. The only plastic container that can be put in the microwave is the PP microwave lunch box, which can be reused after careful cleaning.
