What is a degradable plastic bag?
Is a plastic bag made of degradable plastic:
1. Degradable plastic:
Degradable plastic refers to the addition of a certain amount of additives (such as starch, modified starch or other celluloses, photosensitizers, biodegradants, etc.) during the production process, which reduces its stability and is more easily degraded in the natural environment. plastic.
Classification:
Degradable plastics are generally divided into four categories:
1.Photodegradable plastic
Photosensitizers are incorporated into plastics to gradually decompose them under sunlight. It belongs to an earlier generation of degradable plastics, and its disadvantage is that it is difficult to predict the degradation time due to sunlight and climate change, so it cannot control the degradation time.
2.Biodegradable plastic
Under the action of microorganisms, plastics that can be completely decomposed into low molecular compounds. It is characterized by convenient storage and transportation, as long as it is kept dry and does not need to be protected from light, and has a wide range of applications. It can be used not only for agricultural mulch film and packaging bags, but also widely used in the medical field. With the development of modern biotechnology, biodegradable plastics have received more and more attention and have become a new generation of research and development hotspots.
3.Photo/biodegradable plastic
A type of plastic that combines photodegradation and microorganisms. It has the characteristics of both photodegradation and microbial degradation of plastics.
4.Water-degradable plastic
Water-absorbing substances are added to plastics, which can be dissolved after discarded in water after use. It is mainly used in medical and sanitary equipment (such as medical gloves), which is convenient for destruction and disinfection.
We offer patented full biodegradable film and PVA bag, all products are made by casting equipment, It is different from traditional blow molding products, all blow molding products are non full biodegradable. We can produce pva films and bags in full transparent and various colors. and the PVA film is more smooth than the traditional blow molding products.
we also offer organic material full biodegradable film and bags with patented raw material and production Process.
