【 Abstract 】 :
Plastic pollution has become a very serious pollution problem facing the world. The terrible thing is that our lives seem to have been completely inseparable from plastic bags. With the rise of the fast lifestyle, people's reliance on plastic products is increasing. Fortunately, the pollution problem that plastic bags may bring has attracted social attention. A large number of researchers, packaging plants and even ordinary people are constantly joining the team to protect the environment. Degradable packaging bags have come out. Degradable packaging bag, meaning that it can be degraded. Degradable bags refer to plastic bags that add a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biological degraders, etc.) in the production process to reduce its stability and make it easier to degrade in the natural environment. So what are the plastic materials for degradable packaging bags? Let's listen to professional flexible packaging manufacturer Goolien packing to interpret it for you.
1, Degradable packaging bag - photodegradable plastic
It refers to the material in which the polymer chain breaks down in an orderly manner under the influence of ultraviolet light. Most polymers do not absorb light at wavelengths above 285NM. However, if a photosensitive group or a photosensitive chemical additive is added to the polymer, the process of photooxidation can be accelerated and the degradation can occur rapidly.
2, Degradable packaging bag - biodegradable plastic
From the perspective of biodegradation process, it can be divided into two categories: complete biodegradable plastics and biological collapse plastics. From the preparation method, it can be divided into four kinds: biological fermentation synthesis, chemical synthesis, the use of natural polymers or minerals of animals and plants.
3. Degradable packaging bag - light, oxidation/biodegradable plastic
It is a combination of photodegradation, oxidative degradation and biodegradation in order to achieve complete degradation. It is one of the main research and development directions of degradable plastics in the world. The research of this plastic in the United States has achieved good results.
4, Degradable packaging bag -- thermoplastic starch resin degradable plastic
The starch molecules are allosteric and disordered to form a thermoplastic starch resin, and then add a very small amount of plasticizers and other additives, which is the so-called whole starch plastic. The starch content is more than 90%, and the small amount of other substances added are also non-toxic and can be completely degraded, so the whole starch is truly completely degraded plastic.
