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 compounds that are difficult to degrade naturally. Is it safe to share disposable lunch boxes below? 1

1. What are the hazards of disposable lunch boxes? 1. Adverse gastrointestinal effects: disposable plastic lunch boxes, soaked in hot water and heated by microwave oven, will cause the chemicals added in the lunch boxes 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, and once the shelf life expires, it is likely to bring yellow staphylococcus, 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. Is the disposable lunch box safe? 2

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

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

Thirdly, burning 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 there will be so-called "white pollution" pollution.

I suggest that we should try our best to cook by ourselves, which is healthy and safe. We can't see the physical store when we order takeout online, and many unscrupulous merchants will heat food in plastic packaging and put it into disposable tableware, which is even more harmful.

Advantages of disposable plastic cups:

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

2. Plastic cups can be reused. It can be recycled, which can reduce the pollution to society and save energy.

3. The manufacturing process of the plastic cup is to preheat the plastic sheet at high temperature, stretch molding and blow air. In this process, the plastic cup is sterilized at high temperature, killing harmful bacteria and reducing the harm to human health! And the plastic used in it 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 relatively standardized. After seeing the advantages of plastic cups, we can't ignore their disadvantages. But don't worry, choosing a regular brand of plastic cups and using them correctly according to the instructions will have no impact on people's harm.

Disadvantages of disposable plastic cups:

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

2. Disposable plastic cups are the most unsanitary. After paper cups are baked at high temperature, the plastic film of paper cups will be destroyed.

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 harmful substances, so it can be safely used for a long time.

zero pollution: when the product is buried in the soil, it can be degraded to form carbon dioxide and water after 11 days at a suitable temperature, without causing pollution to the soil and air.

save resources: corn starch is a renewable resource, which is 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, permeability resistance, high temperature resistance and low temperature resistance, and is suitable for freezing in refrigerator, cold storage, fresh-keeping food, microwave heating, etc.
