I make polyethylene boxes in the factory, and when I just make the boxes, the heat will be emitted,

No, unless there is ** material in the raw materials you use, the easiest way is to have no peculiar smell, and if there is a harm to health, then ventilation should be strengthened.

Usually the food packaging materials we call mainly include polymer materials, metals, paper, ceramics, bamboo, glass, fibers and composite materials. Among them, polymer materials include plastics, rubber and coatings, and plastics are the most widely used in the food industry, and toxic plastic products are also the most harmful to people's health. Plastic is a kind of polymer compound, plastic products with synthetic resin as the main raw material, adding an appropriate amount of plasticizers, stabilizers, antioxidants and other additives, processed under certain plasticization conditions.

At present, the food plastics allowed to be used in China include polyethylene, polypropylene, polyvinyl chloride, polycarbonate (PC), polyethylene terephthalate (PET), etc. These plastics have strict production process requirements in the processing process, and the content of free monomers and various additives has strict regulations in the country. The production of plastic products in accordance with the requirements of the national standard is harmless to the human body, but some manufacturers in order to maximize the benefits of the product, at the expense of people's health, the use of polyethylene, polypropylene, polyvinyl chloride and other plastic waste, and a small number of "black-hearted" manufacturers use brushed materials from the clothing industry, waste VCD discs, medical waste (used disposable infusion sets, syringes and blood transfusion sets) as raw materials to produce plastic bags, mineral water buckets, basins and other food appliances.

These tools contain a large number of toxic and harmful chemicals, once the harmful substances in them migrate into the food, it will cause great harm to the human body. For example, after vinyl chloride monomer is absorbed through the gastrointestinal tract, part of it is excreted through the respiratory tract, and the other part is decomposed into ethanol and monochloroacetic acid. It can also bind to deoxyribonucleic acid (DNA) in vivo.

It has toxic effects on the nervous system, bones and liver, and can lead to the occurrence of human angiosarcoma. Formaldehyde is the plasma poison of human cells, and animals ingesting formaldehyde orally can cause hepatocyte necrosis and lymphocyte infiltration. "Acetaldehyde" can damage human nerves, cause dizziness, dizziness, and even cancer.

Prolonged exposure will have an impact, and enhanced ventilation is recommended.

Box, what's it for? Stuffing! What's in it?

Everything obtained by illegal means, of course. You are referring to the common term in hackers, which generally refers to a place used to receive information from backdoors, etc., which can be a database, an email address, etc.

For example, if you hang a web Trojan on the network to get someone else's game account, the Trojan will automatically send the message to the designated mailbox after getting the information, then this mailbox is also a box!

Think about whether you have a nickname called Box or want to be box.

Today's children are like this, not you, just help your parents do more work

Silly boy, you can learn to ask for food on the subway, how many w does it earn a month?

Hurry up and strengthen your workouts in the future! It's okay, it's still too late.

Fortunately, life is in the middle of exercise, and it doesn't matter that no one knows everything.

Learn to do it yourself, if you can surpass what you can, it will be better, and people in the new era will learn to learn and be active.

It's okay, the ability is forced out.

Have you ever seen Zhang Qiling, he is 120 years old and his ability to live is still a ninth-level cripple.

Are you a man or a woman: It's easy to say if you're a woman

It has an impact, from a scientific point of view, the electrical radiation is large, and from the perspective of feng shui, it is easy to bring emergencies such as fires.

It doesn't have much impact, be careful not to get electrocuted!

The meter is generally a gear or planetary wheel structure, as long as it does not produce too much noise, it has no effect on people.

It will not have an impact on human health, but it is necessary to pay attention to safety, do not put the bed under the meter, and do not pile up combustibles under the meter to prevent the circuit from overloading and causing sparks.

In the first case, there will be no electric shock. Because the harm of electricity to people is actually the injury of electricity to people, and after locking people in a sealed metal box, although the metal box is electrified, it is impossible to be electrocuted because there is no current flowing through the human body.

In the second case, not necessarily. If the box is not leaking at all, it will not be electrocuted, for the same reason. If the box is leaking, something similar to a step voltage may occur.

Both water and steel can conduct electricity, and if the box is suspended in the air, it won't, and if it lands, it will.

Yes. But it won't affect your body. It will be fine in the case of ventilation.

Put it well, buddy** does the courier.

There is a lot of wine in the house, and the wine is packaged in a container (bottle or can), as long as the container is not cracked or rotten, it will not easily volatilize the smell of wine, and it has no effect on the human body. However, the packaging of the carton, in the production of non-edible glue and other adhesives, containing lead, aldehyde and other chemical raw materials, long-term indoors, if the ventilation is not smooth, there will be some unfavorable substances (smells) permeated in the air, people live in such an environment for a long time, will have an impact on the body, although it can not be felt, but still pay attention.

There will be no adverse effects on health, your wines are sealed and packaged, and the slight aroma of the wine has a refreshing effect on people.

Definitely ......If the boy doesn't like you, that's his life, my regret......

Work hard, fight for money, others don't care, have your own money, spend money happily,

Don't you know that girls are pandas.

Do your own thing and let others do the talking!
