Is the disposable lunch box safe? Disposable tableware is the product of fast-paced life. Many office workers have the habit of eating out. In fact, the ingredients of disposable lunch boxes are all compounds that are difficult to degrade naturally. Is it safe to share disposable lunch boxes below?

Is the disposable lunch box safe 1 1. What are the hazards of disposable lunch boxes?

1, Gastrointestinal Dysfunction: Disposable plastic lunch box, soaked in hot water and heated by microwave oven, will make the chemicals added in the lunch box dissolve with the food, which is harmful to the stomach.

2. According to the regulations, the main raw material for producing lunch boxes is polypropylene, the content of which is about 80%; As a filler, the content of industrial calcium carbonate should not exceed 20%. The surface of qualified lunch boxes should be smooth, free of impurities and black spots. Inferior disposable lunch boxes contain a lot of toxic substances such as industrial calcium carbonate and paraffin wax, and some of them are made of waste plastics and talcum powder.

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 to children in developing period. After ingesting a large amount of lead, it may affect the nervous system, such as ADHD.

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

5, damage to digestive function: disposable chopsticks are bleached with hydrogen peroxide during the production process, which is 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. Damage to respiratory function: Disposable chopsticks must be fumigated with sulfur in the production process, so when heated during use, SO2 will be released and the respiratory mucosa will be corroded.

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.

Second, what should I pay attention to when using disposable lunch boxes for a long time?

1, low temperature load

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

2. Avoid high temperature heating.

You can't 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 use of styrofoam lunch boxes used by suppliers should be rejected. Compared with wood fiber and plastic lunch boxes, the harm index of foamed lunch boxes is greater.

4. Avoid greasy food.

It's best to avoid packing food containing a lot of oil and sugar in plastic boxes, 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 distinguish the quality of disposable lunch boxes

1, with eyes: colorless, transparent and compact plastic box, its chemical properties are generally stable, and occasional use is also possible.

2. Touch by hand: Feel the texture inside the box. If there is obviously a thick layer of paraffin, the quality of the lunch box will not pass.

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.

Is the disposable lunch box safe? First, long-term use of disposable lunch boxes will have adverse effects on the kidneys and liver of the human body. The composition of disposable lunch box is a compound that is difficult to degrade and has certain toxins. If you use disposable lunch boxes to pack high-temperature food, toxins will be transferred to the food because of the high temperature, and it is not good for people to eat toxic food.

Secondly, the components of disposable lunch boxes are all compounds that are difficult to degrade naturally. Usually, they can only be buried or burned, and both methods will do harm to the environment. Moreover, burying will cause some damage to the soil, thus affecting crops and plants growing in the soil and even affecting the soil structure.

Thirdly, combustion will produce some harmful gases, which will not only pollute the atmosphere, but also adversely affect people's health. In addition, many people's concept of environmental protection is not very strong, and disposable lunch boxes are discarded at will after use, which affects the overall environment of the city and will lead to so-called "white pollution" pollution.

I suggest cooking by yourself as much as possible, which is healthy and safe. We can't see the physical store when ordering takeout online, and many unscrupulous merchants will heat the food in plastic packaging and put it into disposable tableware, which is even more harmful.

Is the disposable lunch box safe? Three advantages of disposable plastic cups:

1. The advantage of plastic cups is that they are light in weight and easy to break.

2. Plastic cups can be reused and recycled, reducing social pollution and saving energy.

3. The plastic cup is made by preheating the plastic sheet at high temperature, stretching and molding, and blowing. In this process, plastic cups are sterilized at high temperature to kill harmful bacteria and reduce the harm to human health! And the plastic used inside can resist high temperature.

4. The investment cost of plastic cups is high, with a certain scale and standard, and the manufacturers of plastic cups are also relatively standardized. After seeing the advantages of plastic cups, we can't ignore its disadvantages. But don't worry, choosing a regular brand plastic cup and using it correctly according to the instructions will have no effect on people's injury.

Disadvantages of disposable plastic cups:

1. As we all know, it pollutes the environment and wastes materials. The edges of disposable cups are coated with waterproof wax. If the water temperature is too high, it will melt the wax. Toxic advantages: easy to carry and use, low price.

2. Disposable plastic cups are the most unsanitary. After the paper cup is baked at high temperature, "the plastic film of the paper cup itself will be destroyed." At the same time, there may be some organic solvents or materials used to make plastic films, and some raw materials will run out. In the long run, it is actually bad for liver and kidney. "

So what are the benefits of degradable disposable cups?

Pollution-free: Because it is refined from corn starch and other environmental protection materials, it does not contain substances harmful to human body and can be used safely for a long time.

Zero pollution: after the product is buried in the soil, it can be degraded into carbon dioxide and water after 1 10 at a suitable temperature, and will not pollute the soil and air.

Save resources: Corn starch is a renewable resource, inexhaustible, while paper tableware and plastic tableware need a lot of wood and petrochemical products. Using corn starch as raw material can save a lot of oil and forest resources.

High quality: the product has good compactness, water resistance, oil resistance, impermeability, high temperature resistance and low temperature resistance, and is suitable for cold storage, cold storage, fresh-keeping food and microwave heating.
