Is it harmful to use plastic bags for high temperature food

1. If the heavy metals in the plastic bag exceed the standard, it will affect the blood system and mental development. Most of the plastic bags for breakfast are disposable plastic bags, which contain various viruses, bacteria and carcinogens, and can produce 16 kinds of toxic substances at high temperatures, which can penetrate into food.

2. The polyvinyl chloride contained in non-food plastic bags is easy to produce dioxins and other harmful substances after being heated and heated, causing diseases of the liver and kidney, central nervous system and blood system.

3. The composition of food plastic bags is mostly polyethylene, which is not easy to decompose as long as it is below 110 degrees Celsius, so it is usually no problem when loading watery food with a temperature of no more than 100 degrees Celsius. However, fried foods that have just come out of the pan, such as fritters, have temperatures that far exceed the tolerance temperature of food bags, which may lead to the production of harmful substances.

The use of food plastic bags to package food, can not be said to be absolutely safe, it should be safe at room temperature, but it is best not to exceed 100, more than 100, the plastic bag will be deformed, will melt, melt on the food, eat it is not good for human health.

The reporter consulted the relevant information and found that the plastic bags currently used in the market mainly include polyethylene, polypropylene, polyvinyl chloride and so on. Among them, plastic bags made of polyethylene and polypropylene can be used to hold food, and the plastic bags used to hold food must be marked with the words "for food", and "non-food" plastic bags will cause certain harm to the human body.

The composition of food plastic bags is mostly polyethylene, which is not easy to decompose below 110, so it is generally no problem to pack food with a temperature of no more than 100. The reporter noticed that most of the plastic bags on the market that were filled with breakfast and set in bowls were disposable plastic bags, and they were not qualified "food" plastic bags. This kind of plastic bag contains various viruses, bacteria and carcinogens, and can produce toxic substances at high temperatures, which will cause great harm to the human body if used for a long time.

Here, this newspaper reminds the public to use less disposable products when dining out, and try not to use bowls covered with plastic bags to pack high-temperature food.

Will it be harmful to eat hot food in plastic bags? It's not too late to know.

It can cause cancer after a long time.

Plastic bags are mostly processed from polyvinyl chloride as raw materials, and most of them are recycled plastics, which will release chlorine and other toxic substances when encountering high temperatures, especially hot porridge and pasta, which will cause cancer after a long time.

In addition, the plastic itself will release harmful gases, due to the long-term accumulation in the sealed bag, the concentration increases with the increase of sealing time, resulting in different degrees of contamination of the food in the bag, especially the impact on the healthy development of children.

Plastic properties. Most of the commonly used food plastic bags are made of polyethylene film, which is non-toxic, so it can be used to hold food. There is also a film made of polyvinyl chloride, and polyvinyl chloride itself is not toxic, but the additives added according to the use of the film are often harmful substances to the human body, which has a certain toxicity.

Therefore, this kind of film and plastic bags made of this film are not suitable for holding food.

If you want to identify PVC plastic bags and polyethylene plastic bags, you can use the following simple method to identify:

Polyethylene film (non-toxic).

The film is milky white, translucent (several layers are stacked to observe it is especially obvious), it feels smooth, as if the surface is coated with a wax layer, shakes vigorously, the sound is brittle, flammable when exposed to fire, the flame is yellow, there is slime dripping when burning, and there is the smell of candles burning.

Polyvinyl chloride film (generally toxic).

If there is no pigmentation, it is transparent, the surface is a little sticky to the touch, shakes hard, the sound is low, it is not easy to burn when it encounters fire, it is extinguished when it is away from the flame, and the flame is green.

What are the hazards to the human body after the plastic bag is heated?

In our lives, do you know what are the dangers of plastic bags to the human body after heating, let's talk about it.

Plastic bags contain a carcinogenic substance--- benzopyrene, benzopyrene has strong carcinogenicity, often use plastic bags to contain food, plastic bags contain benzopyrene will be slowly released, into the food, after the human body eats, will cause human cells to become cancerous. Many people will use a lot of packaging bags to put things in order to conveniently, in fact, it is not advisable, long-term contact with the packaging bag will cause great damage to the internal organs of the body, and will make the body get many special diseases. When the temperature reaches 65, the harmful substances in the disposable packaging bag will penetrate into the ingredients, causing harm to the human liver, kidney function and central nervous system.

Garbage that cannot be degraded enters the sea and land, and is swallowed by animals as food, resulting in the death of animals. In 2019, a young whale was found dead off the coast of the Philippines, and 80 catties of plastic were found in the stomach; 0 Last year, the deer in Nara died one after another, and the culprit turned out to be plastic waste; In 2018, two black swans in the waterfowl breeding area of a park in Shenyang kept pulling a white plastic bag; In 2017, a 700-kilogram leatherback turtle was found dead from eating plastic floating in the sea on the beach of Carrea in Spain. For health, occasional use will not cause major problems, but if this happens for a long time, under the action of high temperature of food, toxic substances may appear in non-food grade plastic bags, which is harmful to health.

The plasticizers contained in plastic bags can cause several kinds of damage to the human body. When buying fritters or buns in the morning, they are usually packed in plastic bags, because the temperature of fritters and buns is very high, so that the plasticizers contained in the plastic bags slowly precipitate out and enter the food, after the human body eats, there may be precocious puberty, cardiovascular diseases, decreased immunity, liver diseases and urinary diseases. Plastic food bags are divided into polyethylene, polypropylene, polystyrene, polyvinyl chloride and other types according to their raw material composition, among which polyethylene and polypropylene are safe plastics that can be used to hold food.

Most PVC plastic bags are toxic, and are made of waste plastic and dyes, such as packaging food, which will cause certain harm to human health.

The high temperature felt by the body is already harmful, and the endotoxin of each packaging bag will be deposited in the body little by little, and we understand that the high temperature of the packaging bag will be harmful. When the temperature exceeds 50, the harmful ingredients in the bag will seep out, and then the environment will pollute the food and cause adverse effects on the body. Storing vegetables in plastic bags for a long time can breed bacteria and cause the vegetables to spoil.

Because the plastic bag is impermeable to the wind when it holds vegetables, coupled with the high temperature of the surrounding environment, it is easy to lead to the growth of bacteria, and after a long time, the vegetables will deteriorate. When people eat spoiled vegetables, it can cause harm to their health.

After the above general understanding, do you understand?

In the heating process, harmful substances will be released, and in the microwave oven, there are more substances harmful to the body, which will form heavy metals such as lead and mercury, which are harmful to health. Excessive use of plastic bags may lead to an increase in toxins. Plastic bags:

Plastic bags are bags made of plastic (commonly used plastics are polypropylene, polyester, nylon, etc.) as the main raw material, which is an indispensable item in people's daily life and is often used to hold other items. It is widely used because of its advantages of cheapness, extremely light weight, large capacity and easy storage, but it is banned from production and use by some countries because of the shortcomings of extremely long degradation cycle and difficult processing of plastic bags.

Plastic heating does not cause much harm to the human body. The composition of plastic bags is often polyethylene, and the commonly used polyethylene plastic is heated non-toxic, and is often used to make fresh-keeping bags, while polyvinyl chloride plastic will decompose toxic gases when heated, but it is also in an extremely high temperature state. The polyvinyl chloride contained in non-food plastic bags can cause liver and kidney diseases, central nervous system and blood system diseases and cause cancer only after heating.

It is toxic to use plastic bags for hot food for a long time, so that the plastic bags will heat up.

The use of plastic bags can release harmful gases by themselves. In particular, cooked food packed in plastic bags often deteriorates after being packaged in plastic bags. The impact of spoiled food on children's healthy development is particularly prominent.

Under normal circumstances, plastic will not cause harm to the human body, but if plastic encounters high temperatures, the harmful substances it produces will harm the body. Most of the plastic bags commonly used in daily life are made of low-density polyethylene materials, and hot melt will occur when these plastic products encounter a high temperature of 110.

The boiling point of edible oil in life and the temperature generated by the microwave oven are much higher than this temperature. If the fried food is directly put into a plastic bag, or the food wrapped in a plastic bag in the refrigerator is directly heated in the microwave, the harmful substances produced by the plastic bag will adhere to the food and enter the human body with the food.

The chemicals contained in plastic products, such as stabilizers, plasticizers, and colorants, contain heavy metals such as lead and mercury, and if these substances are ingested for a long time, they will have a great impact on the liver and kidneys of the human body, and are easy to cause liver damage or kidney damage.

Experts remind that whether you are buying breakfast or lunch, it is best to bring your own container, glass and enamel materials are preferred, or wait for the food to cool before putting it in a plastic bag or plastic container. Do not use plastic bags to hold hot soups such as rice noodles and ramen. In addition, some microwave lunch boxes are made of polypropylene, but the lid is made of other materials, so it is also necessary to see it well in advance.

Usually the main component of plastic bags used by people is polyvinyl chloride, polyvinyl chloride encounters high-temperature food, will produce toxic substances, and will cause chronic poisoning after a long time, for human health, it is best not to use plastic bags to fill hot food.

Plastic bags are an indispensable item in people's daily life and are often used to hold other items.

Plastic bags are cheap, extremely lightweight, large in capacity, easy to store, and impermeable.

The degradation cycle of plastic is extremely long and difficult to dispose of, which not only brings convenience to people's lives, but also brings disasters to the environment, which is called "white pollution".

For many of us, with the development of the economy, everyone will choose to take out or order takeout when they usually eat, but we can't finish eating in the process of eating. When it is hot, I want to use a microwave oven to heat it, and many people heat it directly to the hotel's packaging box or packaging bag for heating, in fact, this is very harmful to the human body and will cause some harm to the human body.

First of all, for plastic bags, its main material is polyvinyl chloride, and most of the materials used in making plastic bags are recycled materials. In this way, when they encounter high temperatures or hot food, they will release toxic substances, which will not only affect our human body, but also cause us to experience dizziness, nausea and even carcinogenic symptoms after long-term use. For many plastic products, they may deform or even dissolve at high temperatures, so that their containing substances stick to food and easily enter our bodies.

AdditivesIn addition, for plastic bags, it not only has such a composition, but even has a variety of additives, which will increase our likelihood of causing cancer and also destroy our immunity. Children's organs are very fragile, and if such plastic bags are used for a long time, it will have a certain impact on their brain intelligence. For most of the plastic bag food can not be heated at high temperature or put in the microwave oven to heat directly, if we want to eat these foods in ordinary times, it is best to pour the food into a bowl and then heat it, so as to reduce some of the danger.

Note that reducing pollution in our lives requires us to do it together, so we also need to learn to reduce waste in the restaurant in normal times, but when we heat these foods, it is better to use some of the more common heating methods. Pour the food into a bowl and heat it up, it will heat up faster and it will be healthier to eat.

The harm to the human body is very great, if the plastic bag is heated, it can destroy the body's immunity, and there is also a risk of carcinogenesis.

The harm is particularly great, and plastic bags are toxic substances, and these poisons will be emitted after heating, which will affect people's health.

The damage to the human body is very large, and sometimes it may even endanger your own life, so the heating of this plastic bag is really a particularly big injury.

Poisonous. Plastic bags contain "plasticizers" that are harmful to human health, which will volatilize faster when heated. Therefore, do not use plastic bags for a long time to prepare high-temperature food, so as to avoid the aggravation of the activity of toxic substances in the plastic bags and the absorption of food into the abdomen of the eater.

Plastic bags are best used to hold vegetables, fruits, cold dishes and other foods.

When the plastic bag is heated, it will produce an unpleasant smell that can be pungent.

Do not use ordinary plastic bags to heat in the microwave, it is better to use microwave-specific plastic bags and special containers for heating.
