The 'white pollution' caused by plastic bags has become a global environmental problem. A Chilean company has invented a new type of plastic bag that can be completely dissolved in water and contains no petroleum derivatives. It is expected to solve the problem that traditional plastic bags are not easily degraded. Environmental problem.
The company, called Solubag, has spent more than four years improving the chemical formula of the current production of plastic bags, including polyvinyl alcohol (PVA), carbon and hydrogen.
The company's general manager Roberto Astet said at a press conference: 'All ingredients of the product have been approved by the US Food and Drug Administration and will not cause harm to the environment. ' He put a new plastic bag In a container filled with water, gently stir with a spoon and the bag is completely dissolved.
'Medical tests prove that this aqueous solution has no effect on the human body.' Astte said that the appearance of plastic bags made with new materials is very similar to that of traditional plastic bags, and the functions are exactly the same. 'Do not worry about rain, manufacturers can Set the temperature at which the plastic bag dissolves when in contact with water. '
He said: 'It takes at least several hundred years for ordinary plastic bags to degrade. The new plastic bags only take a few minutes, and people can use them as many times as needed. When the bags are damaged, they can be dissolved anytime and anywhere.
The company's R&D staff said that after continuous improvement, the cost of new materials has been significantly reduced compared to the initial stage of development, suitable for mass production and market.
According to UNEP data, more than 500 billion plastic bags are used every year in the world, and plastic pollution has caused serious damage to human living environment.
