Is disposable transparent plastic tableware poisonous? With the rise of the take-away industry, disposable transparent plastic lunch boxes, as a product of the rapid pace of life, are widely used because of their convenience and no need to wash. Is that disposable transparent plastic tableware toxic? Is disposable transparent plastic tableware toxic? 1

Disposable lunch boxes are foamed plastic tableware. If the food contained exceeds 65 degrees, it will precipitate its own toxins and invade the food, just like plastic bags can't meet high temperatures. Moreover, if the processing technology is not well controlled, the toxicity will be even greater. Eating with such lunch boxes is equivalent to chronic poisoning. Although the toxicity is weak, it will still cause harm to the liver and kidneys after long-term use.

At present, the disposable fast food box is made of different materials, and its toxicity is different. However, the disposable fast food box is an industrial product, and it will be toxic to the body if it is used for a long time.

Suggestions:

1. Disposable lunch boxes should be used sparingly and carefully at ordinary times, and it is better to bring your own lunch boxes, which is both sanitary and economical.

2. If it is not clear whether the lunch box is made of pure PP, it is best not to heat it in the microwave oven.

3. The foamed plastic lunch boxes used by vendors should be rejected.

4. Some bad manufacturers add plasticizers to facilitate processing. Generally, this plasticizer is soluble in oil. If it is hot oil, it is more soluble. Therefore, if there is oil in food, a small amount of plasticizer will be dissolved in oil and then transferred to food. If it is exposed to plasticizers for a long time or excessively, it will have a certain impact on the body.

You need to distinguish the advantages and disadvantages when using disposable lunch boxes, and qualified lunch boxes can be used safely. Try to avoid using disposable lunch boxes to contain high-temperature food, fried food, vinegar and cooking wine mixed food.

1. What are the hazards of disposable lunch boxes

1. Adverse gastrointestinal effects: A disposable plastic lunch box, soaked in hot water and heated in a microwave oven, will cause the chemicals added in the lunch box to dissolve with food, which is unfavorable to the gastrointestinal tract.

2. According to regulations, the main raw material for producing lunch boxes is polypropylene, with a content of about 8%; As a filler, the content of industrial calcium carbonate should not exceed 2%. The surface of qualified lunch boxes should be smooth and free of impurities or black spots. The inferior disposable lunch boxes contain a lot of toxic substances such as industrial calcium carbonate and paraffin wax, and some also use waste plastics and talcum powder to produce lunch boxes.

3. It is worth noting that industrial calcium carbonate contains a large amount of heavy metal-lead, which is also very harmful to the digestive tract and nervous system of human body, especially for children, who are in the developmental stage. After ingesting a large amount of lead, it may affect the nervous system, such as ADHD.

4. Germ infection: The shelf life of sterilized disposable chopsticks is up to 4 months. Once the shelf life has passed, it is likely to bring staphylococcus aureus, Escherichia coli and hepatitis.

5. Impairment of digestive function: Disposable chopsticks are bleached with hydrogen peroxide in the production process, which is highly corrosive and causes corrosion to the mouth, esophagus and even gastrointestinal tract; If talcum powder is used in the grinding process, it will accumulate slowly in the human body and cause gallstones.

6. Impairment of respiratory function: Disposable chopsticks must be fumigated with sulfur during the production process, so SO2 will be released when exposed to heat during use, which will corrode respiratory mucosa.

7. Disposable plastic lunch boxes have become a part of our daily life, whether it is luxury hotels or food stalls along the street; Whether it is a bus station or an airport, you can see their shadows everywhere. But they are not only harmful to human body, but also difficult to degrade, pollute the environment and are not environmentally friendly.

2. What should you pay attention to when using disposable lunch boxes for a long time

1. Put them in low temperature

If you go to a restaurant to buy lunch boxes to take away, it is recommended to wait until the meals are completely cold, so as to avoid the dissolution of harmful substances in the lunch boxes caused by high temperature.

2. Avoid high-temperature heating

Do not use disposable lunch boxes to heat food in the microwave oven unless there is a clear sign on the lunch box that can be used in the microwave oven.

3. Use less foamed disposable tableware

The foamed plastic lunch boxes used by vendors should be rejected. Compared with wooden fiber and plastic lunch boxes, the harm index of foamed lunch boxes is greater.

4. Avoid foods filled with oil

It is best to avoid using plastic boxes to pack foods containing a lot of oil and sugar, because the boiling point of oil easily exceeds the heat resistance limit of plastic, and oil, sugar and plasticizer are all organic substances, which are similar to each other.

How to tell whether a disposable lunch box is good or bad

1. Look at it with your eyes: a colorless, transparent and dense plastic box is generally stable in chemical properties and can be used occasionally.

2. Touch by hand: Feel the texture inside the box. If you obviously feel a thick layer of paraffin, the quality of the lunch box is not up to standard.

3. Smell with your nose: A good disposable lunch box has no obvious odor, and any lunch box with pungent smell is an unqualified product.

to sum up, there are six jingles: the fingers are soft, they break when they are gently torn, they smell pungent and smelly, they leak easily when they are deformed by heat, they have paraffin marks when they are folded, and they sink when they are torn into water. Any of the above situations shows that its quality is not too hard, and long-term use will have an impact on the human body, which is equivalent to chronic suicide.

1. Whether disposable plastic tableware is toxic is beyond doubt. We all know that a certain amount of plasticizer will be added to plastic products to enhance the flexibility of tableware, which will make tableware easier to process and plastic. As everyone knows, there are a lot of harmful substances in it, which will bring serious diseases to the body. We should take the initiative to understand it.

2. Because a large amount of plasticizer is added to plastic tableware, when the tableware exceeds a certain heat resistance limit, it will lead to the release of plasticizer, which will interfere with the endocrine system of human body, especially the reproductive system of men, so everyone must pay attention to it.

3. According to some studies, some plastic lunch boxes are made of different grades. Pure plastic tableware is very safe, but there are still some materials mixed with other impurities, which will lead to the precipitation of harmful substances after heating, so we should also pay attention to it.

In the face of the toxic situation of disposable plastic tableware, it requires everyone to develop the ability to identify black lunch boxes. We want to identify whether disposable plastic tableware is a toxic material, which requires us to touch

If it is a lunch box made of recycled waste or talcum powder, its strength is generally poor, and it will break when it is gently torn, which requires us to pay attention to it. In addition, we can smell whether the lunch box has an odor and is qualified.

1. What are the raw materials of disposable plastic lunch boxes?

disposable plastic lunch boxes are made of two kinds of materials: PP, PP and PS polystyrene.

The former is soft to turn over, and can withstand the temperature of -6 to +12 degrees;

The latter is hard and transparent, and its maximum tolerance temperature is 75 degrees. When it exceeds 75 degrees, toxic styrene monomer will be precipitated, which is not suitable for hot meals.

2. Are all manufacturers legally producing?

in order to reduce the cost, some manufacturers use PP as the box and PS as the box cover, which reduces the cost and is not too harmful.

However, some unscrupulous manufacturers use recycled waste or recycled materials to make lunch boxes, and add harmful substances such as calcium carbonate, paraffin wax and talcum powder. Long-term consumption can cause cancer.

The identification method is to fold the lunch box. If the white wax print at the crease is particularly obvious, it is a carcinogenic lunch box.

To sum up, first of all, it is best not to overheat the food in plastic boxes; Secondly, we should pay attention to identify the quality of plastic boxes; Finally, if you don't need it, you don't need it. Your own food is the healthiest! Is the disposable transparent plastic tableware toxic? 3

1. Is the disposable plastic bowl safe? 1. The disposable plastic bowl contains a lot of hazards, such as plasticizers. When the tableware exceeds the heat resistance limit, the disposable plastic bowl releases plasticizers, which will damage the human liver and kidneys and affect the endocrine system.

2. In addition to the release of plasticizer from plastic bowls caused by high temperature, dissolved organic matter may also cause the release of harmful substances from disposable plastic bowls. For example, when cooking, we often use cooking wine, vinegar and other seasonings, and vinegar and cooking wine will produce ethyl acetate, which will destroy the benzene ring of polymer materials in disposable plastic bowls and make the substances in plastics transfer to food.

3. According to the inspection results of the Quality Supervision Bureau, the qualified rate of disposable plastic bowls and other products is less than 7%, and its safety hazards are relatively large. Some pure plastic tableware is relatively safe, but inferior disposable plastic bowls will lead to excessive dissolved residues, causing indigestion and even heavy metal poisoning.

Second, how to choose plastic products

Generally, there will be 1-6 logos on the bottom of plastic products, and we need to pay attention to what the logos are when buying plastic products. For example, the plastic product marked 5 is made of PP, which can withstand the high temperature of 13 degrees. It is the only food that can be heated in the microwave oven, but its transparency is poor.

the plastic product marked 6 is made of PS material, and it can't be put into the microwave oven, nor can it contain strong acids and alkaline substances.

When we buy plastic products, we can smell whether the products have peculiar smell. Generally, qualified products are tasteless.

when buying plastic products, we should check whether the product information is complete, whether the plastic products are marked for food, and whether the plastic products are clean and free of impurities.

if we buy plastic toys, we should check whether the products have 3C certification, and try to choose toys with relatively thick amplitude and corner position. Usually, high-quality plastic toys are made of PVC, PP, PE and other materials, and their colors are bright.
