Eco Friendly PLA Plastic Bag Biodegradable Packaging Bag

It is a plastic bag made of degradable plastic:
1.Degradable plastics:
Degradable plastic refers to a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biodegradants, etc.) added in the production process to reduce its stability and then easily degrade in the natural environment.
2.Classification:
Degradable plastics are generally divided into four categories:
①Photo degradable plastic
Incorporating photosensitizer into plastics, the plastics are gradually decomposed under sunlight. It belongs to an earlier generation of degradable plastics, and its disadvantage is that the degradation time is difficult to predict due to changes in sunlight and climate, so the degradation time cannot be controlled.
②Biodegradable plastics
The desired effect is a plastic that can be complete as a molecular group medicine field. With modern biotechnology, more and more attention has been paid to biodegradable plastics, which has become the development trend of research and development.
③Light/biodegradable plastics
A type of plastic that combines photodegradation and microorganisms, it has the characteristics of light and microorganism degradable plastics at the same time.
④Water-degradable plastics
Add water-absorbing substances to plastics, which can be dissolved in water after use. It is mainly used in medical and sanitary utensils (such as medical gloves), which is convenient for destruction and disinfection.
3.Introduction:
Tests have shown that most degradable plastics begin to be thinning, lose weight, lose strength, and gradually break into pieces after 3 months of exposure in the general environment. If these fragments are buried in garbage or soil, the degradation effect is not obvious.
