Principle of Compostable Biodegradable Plastic Bag

Compostable Biodegradable Plastic Bag includes plastic bags that can be degraded by physical and biological factors (light or heat, or microbial action). The so-called aerobic degradation (that is, accelerated degradation by catalysts or activators at high temperatures) or photodegradable starch-polyethylene plastics will cause some environmental problems. These Compostable Biodegradable Plastic Bag materials do not degrade as fast as compostable plastics and may leave debris. These degraded water-repellent fragments have a large surface area and may migrate to groundwater and soil. Some hydrophobic highly toxic substances such as PCB and DDT, such as PCB and DDT, are adsorbed and retained on the surface, making the content of toxic substances as high as 1 of the background content. Millions of times, enough to become a delivery system for toxic substances in the environment. Therefore, it is necessary to ensure that the product is completely biodegradable in a very short time determined by the treatment facility.
