Will eating food in plastic containers do harm to your body

some people believe that eating food packaged in plastic containers often will be harmful to the body, because these plastic containers will release a load of ± 500000 yards; Plasticizers, bisphenol A, dioxins, heavy metals and other harmful substances are not divided inside and outside

1. Plasticizer

plasticizer, also known as plasticizer, is an additive used to add hard plastics to make them more elastic and durable. No. 3 (PVC) is the hard plastic that most often uses plasticizers. Plastic containers made of PVC contain plasticizers. However, No. 1, No. 5 and No. 6 plastic, which are most commonly used in takeaway plastic containers, are soft plastic, which are elastic and do not need to use plasticizers

even take away plastic containers made of PVC materials, as long as they are qualified products produced by regular manufacturers and used correctly (for example, they are not used to contain high-fat food, and the use temperature will not be too high), there will not be excessive plasticizers released into food

2. Bisphenol A

it is said that disposable lunch boxes made of plastic or resin contain an estrogen like substance called bisphenol A, which will ooze out of the lunch box after high temperature and enter the body with food. Human body will cause cancer if it is exposed to bisphenol A for a long time

bisphenol A is a chemical raw material, and bisphenol A in food contact materials may indeed be transferred to food. However, bisphenol A is not required for No. 1, No. 5 and No. 6 materials mainly used in takeaway plastic containers. As for the harm of bisphenol A to human body, there is no definite conclusion at present. For example, as for carcinogenicity, animal studies have not provided convincing evidence that exposure to bisphenol A has carcinogenic risk

3, dioxin

it is also said that No. 1 (PET) plastic will release dioxin when refrigerated. Dioxins are toxic and carcinogenic

however, at present, there is no reasonable scientific evidence to show that No. 1 (PET) plastic itself contains dioxins, and dioxins will not be produced under refrigeration temperature

4. Other chemicals

molding properties

some other chemicals used to make plastics may also be released into food. For example, plastic containers made of material No. 1 (PET) contain trace amounts of antimony

antimony is a heavy metal used to make pet. When the plastic container of No.1 (PET) material is filled with water, the antimony contained can be released into the water. However, research shows that the antimony content of PET bottled beverages is very low (far lower than the guidelines set by the World Health Organization on the quality of drinking water), and will not pose a risk to health

in fact, China has adopted many test methods for the transmission system of some metal material tensile machines in the plastic containers that are now on the market. In many test methods, spherical pins or balls are used to take one sample. There are also limited standards for reducer chemicals. For example, antimony in plastic containers made of No. 1 (PET) material should be less than or equal to 0.05 mg/L

in a word, we don't have to worry too much about the safety of qualified disposable plastic containers produced by regular manufacturers. Of course, it's not a good thing to eat takeout too often, for example, it's difficult to guarantee nutrition balance, hygiene, etc
