What is a PVC degradable plastic bag?
Jul 27, 2018


Have you heard of degradable plastic bags? Now the PVC bag factory is here to tell you what is a degradable plastic bag.


Degradable plastics are plastics that are degraded by the action of microorganisms such as bacteria, molds (fungi) and algae found in nature. Raw material mixing is the first step in the production line of plastic bags. First, after mixing polyethylene and masterbatch, an opaque white granule is added. These white granules are called degradable masterbatch and are the key features of degradable plastic bags. Its composition is calcium carbonate.


According to the introduction of the PVC bag factory, the degradable plastic bag can be degraded by the action of sunlight, temperature, moisture and microorganisms under the action of sunlight, temperature, moisture and microorganisms. It will break down into broken pieces and be gradually absorbed by the natural environment. . The masterbatch mainly determines the color of the degradable plastic bag after it is produced. Degradable plastic bags can be divided into two types: fully biodegradable plastics and destructive biodegradable plastics.


Destructive biodegradable plastics: Destructive biodegradable plastics currently mainly include starch modified (or filled) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, and the like.


Completely biodegradable plastics: Completely biodegradable plastics are mainly made from natural polymers (such as starch, cellulose, chitin) or agricultural by-products by microbial fermentation or synthesis of biodegradable polymers, such as thermoplastic starch plastics, aliphatic Polyester, polylactic acid, starch/polyvinyl alcohol, etc. are all such plastics.


Through the above analysis, we will find that PVC cosmetic bags and PVC waterproof phone bags produced by PVC bag factory are also a kind of degradable plastic bags. They are environmentally friendly and healthy plastic bags, so you can use them with confidence.
