Degradable materials have become a new low-carbon and environmentally friendly way

  Safety, health and environmental protection are the low-carbon lifestyles currently advocated. It is the general trend to choose degradable materials that meet the requirements of the times. We need to learn how to properly select degradable materials. Before this, many people had some doubts about whether the degradable packaging bag is harmful to the human body. Next, Xiaobian Huiguo will explain it to you.

  Plastic chemical bonds used in degradable materials are not very strong, so plasticizers are not easy to migrate to the middle layer of plastic, causing food contamination. Migration has two prerequisites. One is an oily environment, where the packaging is high in oil, and the other is heat, which migrates into the food when heated. Therefore, plastic bags are used to package various soups and water, and there may be migration and deposition of plasticizers.

  We also need to know that plastics are structurally stable, not easily degraded by natural microorganisms, and do not separate for a long time in the natural environment. This means that if waste plastics are not recycled, they will become pollutants that continue to accumulate in the environment for a long time, causing great damage to the environment.

  The damage is mainly manifested in several aspects. First, it affects agricultural development. The continuous accumulation of waste plastic products in the soil will affect the absorption of nutrients and water by crops, resulting in reduced crop yields. Second, the survival of animals is threatened. Discarded plastic products are thrown into the land or water and eaten by animals as food, causing the animals to die. A shortened film is a thermoplastic film that is stretched and oriented during production and treated with hot air or infrared radiation during use. After heat treatment, the film is tightly wrapped on the package, and the cooling stage is shortened to a certain value, which can be stored for a long time.

  Degradable materials are bound to become a new trend. From an environmental protection point of view, we all use it to contribute to our green cause.
