First, harmful substances contained in plastic bags are released and contaminate food. If these contaminated foods are eaten, people are prone to symptoms of food poisoning such as vomiting and diarrhea. This will not only affect human health for a long time, but also have a huge impact on the healthy development of children.Second, do not use ultra-thin plastic bags. Ultra-thin plastic bags are light in weight and thin in thickness, but they have a certain load-bearing capacity. Looks good, do you know how these ultra-thin plastic bags can achieve such performance? That’s because plastic bag manufacturers have added plasticizers in the production process, and this plasticizer is extremely harmful to human health. National laws and regulations also prohibit manufacturers from producing and selling plastic bags with a thickness lower than2.5cultra-thin plastic bag. Moreover, ultra-thin plastic bags are of poor quality and difficult to recycle, which is not in line with the concept of environmental protection.Third, do not use plastic bags for alcoholic foods. Why? Because alcoholic food will dissolve the lead in the polyvinyl chloride plastic bag into the food. As we all know, lead is a heavy metal that is toxic to the human body. Once a person absorbs excessive lead, severe abdominal cramps, anemia, toxic liver disease, toxic kidney disease, and multiple peripheral neuropathy will occur.Fourth, ordinary plastic bags cannot contain food and heat it in a microwave oven. Heating plastic bags is easy to produce carcinogens, which is very harmful to human health. Consumers should use special microwave ovens to heat plastic films for heating. Consumers should use special food packaging bags to hold food, especially plastic bags with particularly dark colors, which are likely to be reprocessed from recycled plastics and should be resolutely avoided for food packaging.Mastering the correct method of using plastic bags can not only prolong the service life of plastic bags, but also protect personal health.
