Do foods in plastic containers often cause harm to the human body?
With regard to plastic containers , it brings convenience to our lives and also brings certain harm to our bodies. Frequent eating of food packaged in plastic containers can cause certain harm to the human body because these plastic containers release harmful substances such as bisphenol A, plasticizers, dioxins, and heavy metals.
1, bisphenol A
A disposable lunch box made of plastic or resin containing an estrogen-like substance called bisphenol A. It can ooze out of the lunch box after high temperature. If the food enters the human body, the human body will be in contact for a long time. Bisphenol A can cause cancer. Bisphenol A is a chemical raw material. Of course, bisphenol A in food contact materials may indeed be transferred to food. However, the three types of materials, No. 1, No. 5 and No. 6, which are mainly used for take-out plastic containers, No need to use bisphenol A. As for the harm of bisphenol A to the human body, there is no clear conclusion yet.
2, plasticizer
Plasticizers, also known as plasticizers, are plastic additives that are added to hard plastics to make them more flexible and durable. No. 3 (PVC) is a hard plastic that most commonly uses a plasticizer, and a plastic container made of PVC contains a plasticizer. However, the No. 1, No. 5, No. 6 plastics most commonly used in take-away plastic containers are soft plastics, which are inherently flexible and do not require the use of plasticizers. Even the take-out plastic containers made of PVC materials, as long as they are qualified products produced by regular manufacturers, and are used correctly (for example, foods that are not used for high-fat foods, and the use temperature is not too high), there is no excessive plasticization. The agent is released into the food.
3, dioxins
Some people think that PET (Plastic) No. 1 releases dioxin when it is refrigerated. Dioxins are toxic and can cause cancer. However, there is currently no reasonable scientific evidence that the No. 1 (PET) plastic itself contains dioxins and does not produce dioxins at refrigerated temperatures.
4. Other chemicals
Some other chemicals used to make plastic may also be released into the food. For example, a plastic container of No. 1 (PET) material contains trace amounts of hydrazine. Tantalum is a heavy metal used in the manufacture of PET. The plastic container of No. 1 (PET) material can be released into the water when it is filled with water. However, studies have shown that the content of strontium in PET bottled beverages is very low (far below the World Health Organization's guidelines for water quality) and does not pose a risk to health. In fact, some chemical substances in plastic containers are limited in China. For example, plastic containers in No. 1 (PET) materials should be less than or equal to 0.05 mg/L.
