In daily life, it is common for every family to use plastic bags, plastic containers, and other foods that are packed in plastic containers. As we all know, plastics used to package and hold food should be non-toxic. But sometimes people do not pay attention to this issue and readily pick up a plastic bag and use it to hold food. They do not know that doing so is harmful to the body. Because these plastic bags are added with the plasticizer dibutyl phthalate and dioctyl phthalate during the manufacturing process, they are toxic, and the added stabilizer, lead stearate, is also toxic. In addition, lead and salt are easily precipitated, and once they enter the human body, they will have a collection function. For a long time, they cause poisoning. Therefore, special food bags and boxes must be used for packaging and serving foods in plastic products. They must not be used indiscriminately.

At present, the plastic packaging used in beverage products is generally a PET plastic bottle, which is heat-resistant to 70° C. It is only suitable for warm drinks or frozen drinks. It is easily deformed when it is filled with hot liquids or heated, and substances that are harmful to the human body are melted. Therefore, when the bottle is used up, it is discarded. Do not use it as a cup, or use it as a storage container.

Items, so as not to cause health problems more harm than good.

For people's favorite bowl of instant noodle boxes and snack boxes, because they contain PS, although they are both heat-resistant and cold-resistant, they cannot be put into a microwave oven to avoid release of chemicals due to high temperatures. They like to use microwave ovens to cook instant noodles. Friends must pay attention. And can not be used to take a strong acid (such as orange juice), a strong alkaline substance, because it will break down the body of polystyrene is not good, easy to cause cancer.

The PC material plastic is generally used to make kettles, cups, bottles. The safety performance of PCs in milk bottles is also controversial because of the presence of bisphenol A. Many countries in Canada and other countries have already banned bottles containing bisphenol A. In theory, as long as bisphenol A is 100% converted into a plastic structure during the production of PC, it means that the product is completely free of bisphenol A, let alone released. However, if there is a small amount of bisphenol A plastic structure that does not convert to PC, it may be released into food or drink. Therefore, be careful to use caution when using this plastic container. Residues of bisphenol A in the PC, the higher the temperature, the more the release, the faster the speed. Therefore, you should not use PC water bottles to hold hot water, so as not to increase the release rate and concentration of BPA (if any).
