According to a news released by Reuters on August 3rd, a research and development team in Chile has developed a brand new plastic bag that may provide a completely new solution to the problem of “white pollution”.
It is understood that the team uses polyvinyl alcohol (PVA), carbon and hydrogen (excluding petroleum derivatives) that can be dissolved in water as a chemical matrix to make degradable plastic bags by changing the molecular structure of petroleum derivatives. And to ensure that the plastic bag degrades over time.
At the product launch, the general manager of the research team said that the ingredients used to make the plastic bags would not cause any harm to the environment and have been approved by the US Food and Drug Administration. In order to prove that the water dissolved in the plastic bag is harmless to the human body, the company’s technical engineer took a direct drink during the demonstration.
“The main difference between traditional plastics and our plastics is that traditional plastics can last 150 to 500 years in the environment, and our plastics last only five minutes. You can decide when to destroy it.” An engineer at the research team If so.
Although many people say that plastic bags that can be easily dissolved in water should have a lot of things, such as liquids, fruits, vegetables, fish, seafood, etc. For this problem, the Chilean research team said that in addition to plastic bags that can be dissolved in cold water, a reusable canvas bag that can be decomposed in hot water has been developed.
It is understood that this kind of water-soluble plastic bag can be produced anywhere. The research team’s company is seeking production cooperation manufacturers around the world. China is one of the goals that they attach great importance to.
