Plastic degradation methods, the forms we currently know can be divided into biodegradable plastics, photodegradable plastics and environmentally degradable plastics.
(1) Biodegradable plastics refer to a class of plastics that cause degradation under the action or influence of microbial conditions in natural environments such as bacteria, molds (fungi) and algae.
(2) Photodegradable plastics refer to a class of plastics that are degraded by sunlight in the natural environment.
(3) Environmentally degradable plastics are plastics that are exposed to natural environmental conditions and are degraded by a combination of conditions such as light, heat, water, oxygen, pollutants, microorganisms, insects, and wind, sand, rain, and mechanical forces. A class of plastic.
(4) Hydrolytically degradable plastics This type of degradable plastics is water-soluble and biodegradable, such as polyvinyl alcohol, polyvinyl alcohol / starch-degradable plastics.
(5) Photodegradable plastics This type of degradable plastics refers to polymeric resins with groups that are easily degraded by light. Such as ethylene / carbon monoxide copolymer (E / CO), carbon dioxide copolymer (also biodegradable) or adding a photosensitizer to the PE / PP general-purpose resin to constitute a photodegradable plastic.
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.
