When it comes to plastic bags, people will think that they will cause “white pollution” to our environment.
In order to reduce the pressure of plastic bags on the environment, China has also issued a special “plastic restriction order”, but the effect is limited, and some experts say frankly that the “plastic restriction order” only delays the harm of plastic and does not fundamentally solve this problem.
However, everyone’s life is really inseparable from plastic bags. Now a new type of plastic bag has come out.
A seemingly ordinary white plastic bag. Put it in hot water at about 80 ℃. A few seconds later. The plastic bag disappeared.
It is reported that this seemingly ordinary plastic bag can be dissolved in a few seconds as needed, and 100% degraded into carbon dioxide and water within half a year, which is very environmentally friendly.
The raw material of this kind of plastic bag is polyvinyl alcohol, which comes from starch alcohol such as cassava, sweet potato, potato, corn and so on. It is a colorless, non-toxic, non-corrosive, fully biodegradable water-soluble organic polymer. The material can be completely degraded into carbon dioxide and water without treatment.
Therefore, we can see that all kinds of plastic bags made of this material are soluble in water. The product has obtained the patent invention certificate issued by the State intellectual property Office, and the relevant departments have also passed the inspection of the product.
After dissolving into water, this material will be further completely degraded and become carbon dioxide and water, which will not pollute and destroy the water quality of the source. Moreover, if the water dissolves into the soil in nature, it will not only not pollute and destroy the soil quality, but also has obvious soil improvement effect. It is an environment-friendly material.
Because of its complete degradability, the project product is known as “edible plastic”.
It is understood that the production process of the project is also green and environmentally friendly, without adding any additives, producing three wastes and not polluting the environment. Biogas, a by-product produced in the process of producing raw materials, can be used for power generation and heating, and the waste residue can be made into organic fertilizer to return to the farm to realize the recycling of resources. it can be said that it is a completely green environmental protection project.
