Flexible packaging. Specifically, it is called plastic flexible packaging.

Max Schuschny Max Schuschny invented plastic. In 1866, John Wesley Hyatt invented plastic by accidentally knocking over collodion and discovering that it would turn into a tough and elastic material when frozen"Celluloid" (celluloid )。
On October 24, 1902, Austrian scientist Max Schuschny invented the plastic bag. The packaging was light and strong, and at the time it was a technological revolution, when people went out shopping, they felt relaxed and didn't need to carry anything, because the shops and vegetable markets had free plastic bags.
But at that time, he was already aware of the harm caused by plastic bags, so he asked the boss not to let the plastic bags go on the market before he found a degradable way, and his sullen boss agreed, but his boss broke his promise driven by interests, so the great engineer finally chose to commit suicide in order to defend his dignity, which can be said to be a very responsible person.
Since most plastic bags are produced from non-renewable degradable materials, the disposal of these white waste can only be done by digging up the soil for landfill or incinerating it at high temperatures. Neither approach is environmentally friendly. According to scientists, it takes more than 200 years for plastic bags to decay when buried in the ground, and they seriously pollute the soil.
The harmful smoke and toxic gases produced by incineration will also cause pollution to the atmospheric environment.

Humanity's worst invention.
In 2002, the British newspaper The Guardian named "the worst invention of mankind", and the plastic bag unfortunately "won" this title - because the earth we now live in seems to have become a "plastic planet", with land, rivers, mountains, oceans ......Plastic is already ubiquitous. Until one day, we are all gone, and these guys still occupy the earth because they are "immortal".
The newspaper said that the cockroach was once hailed as a symbol of tenacious vitality, but since the advent of plastic bags, it has even surpassed cockroaches and will become the last witness of human civilization - it is believed that it will carry human history into the next ice age. Plastic was "born" in the 30s of the 20th century, and from the 70s, plastic bags monopolized the market for supermarket shopping bags in Europe and the United States. The UK alone now uses 8 billion plastic bags a year.
Every time people use a brand new plastic bag for something, one should think about it – maybe one day a turtle will swallow it as a delicious jellyfish and die a tragic death of suffocation.
Plastic food bags cause extremely serious pollution to the ecological environment. Its molecular structure is very stable, and it is difficult for light, heat, bacteria and enzymes in nature to dissolve it, and it will not differentiate and degrade even if it is buried in the soil for hundreds of years; Incineration of plastic is not the solution, the chloride and heavy metal ions remaining in the atmosphere after plastic combustion will seriously endanger human health and the ecological environment, so the accumulation of a large number of discarded plastic bags has caused serious pollution of farmland and rivers, and damaged the ecological environment in which we live.
Compared to other countries, South Africa has more "white pollution". Strong winds blow and plastic bags often hang on the trees, and residents think it's snowing. In order to reduce environmental pollution, since March 2001, Ireland** has introduced a plastic bag tax of 9p per plastic bag.
The UK has taken another step to make plastic bags from biodegradable materials. Other countries are now following the lead and working to remedy the "worst invention". But I don't know when human beings can say goodbye to the "plastic era", and the degradable environmental protection bags made by Tianzhuang environmental protection can be very powerful without pollution to the environment.

Because the harm that plastic bags bring to humans far exceeds the convenience it brings to humans. On the one hand, plastic bags contain a lot of additives, which endanger the health of the body, especially children, and plastic bags are difficult to degrade and pollute the environment.

Because he is like a cancer, harming the environment and never going away. What's worse is that plastic products are all over the corner of life, and the number is huge, so its harm can be imagined. And this hazard is very chronic, so it is very easy for people to ignore.

First, it affects agricultural development. The accumulation of waste plastic products in the soil will affect the absorption of nutrients and water by crops, resulting in reduced crop yields.
Second, it poses a threat to the survival of animals. Waste plastic products discarded on land or in water bodies are swallowed by animals as food, resulting in the death of animals. Nearly 1,000 sheep from 20 herdsmen in Qinghai Lake died as a result, causing an economic loss of more than 300,000 yuan.
Sheep like to eat the oily residue wrapped in plastic bags, but often eat together with plastic bags, because the eaten plastic remains in the stomach for a long time and is difficult to digest, these sheep's stomachs are crowded, can no longer eat, and can only be starved to death. This kind of thing is not uncommon in zoos, pastoral areas, rural areas, and oceans.
Third, waste plastics will not only occupy a large amount of land with landfills, but also the occupied land will not be restored for a long time, affecting the sustainable use of land. If the waste plastic products that enter the domestic garbage are landfilled, they will not degrade for 200 years.

1. From the perspective of environmentalists who really consider nature, the use of plastic bags is to pollute the environment and destroy nature, which means that we will harm ourselves and advocate the use of less or no plastic bags.
2. For ordinary people, plastic bags are convenient, and they don't know the impact on natural collapse, so they have an indifferent attitude.
3. For plastic factories, it must be that the more people who use it, the better, after all, the company is based on profits, and many unscrupulous businessmen will not care about the impact of the use process at all, so naturally they advocate the production of plastic bags with high skin rounds.
Roughly these three situations are the same.

The main component of plastic is polyethylene, which belongs to organic synthetic materials; Plastic products are difficult to degrade and can easily cause white pollution, so the significance of restricting the production and use of plastic shopping bags: it can save some petroleum resources and help reduce white pollution
Therefore, the answer is: plastics are organic synthetic materials; It can save part of the oil resources; It is beneficial to reduce white pollution
1. In terms of superstition. Chinese are dead, but also Chinese ghosts, although in the six provinces do not define the nationality, but the traditional Chinese still focus on hometown, the older generation of Chinese most taboo is to die in a foreign country, pay attention to the soul to return to their hometown, therefore, before the old overseas Chinese die, most of the last wishes are "born to be Chinese, death is the soul of China, send me back after death". >>>More
According to the data from the 2018 China Statistical Yearbook released by the National Bureau of Statistics, from 2013 to 2017, the per capita disposable income of Chinese residents was as follows: yuan, yuan, yuan, yuan, and yuan. >>>More

According to relevant information, the average age of Chinese is years.
It's still good, insurance is actually an additional protection, which is to fulfill its function according to your own wishes, and people's needs may be different, which may lead to different effects.
