What are the types of degradable plastic bags?

1. Photodegradable plastic bags

A photosensitizer is added to the plastic to gradually decompose the plastic under sunlight. It belongs to the older generation of degradable plastics, and its disadvantage is that the degradation time is difficult to predict due to sunlight and climate change, so the degradation time cannot be controlled.

2. Biodegradable plastic bags

Under the action of microorganisms, plastics can be completely decomposed into low-molecular-weight compounds. It is characterized by convenient storage and transportation, as long as it is kept dry, it does not need to be protected from light, and has a wide range of applications, which can not only be used for agricultural mulch film and packaging bags, but also widely used in the field of medicine. With the development of modern biotechnology, biodegradable plastics have received more and more attention and have become a new generation of hot spots for research and development.

3. Photo/biodegradable plastic bags

A class of plastics that combine photodegradation and microorganisms, it has the characteristics of photodegradable plastics with both light and microorganisms.

4. Water-degradable plastic bags

Absorbent substances are added to plastics, which can be dissolved in water after use, and are mainly used in medical and sanitary appliances (such as medical gloves) to facilitate destruction and disinfection.
