In recent years, with the rapid development of economy, people's pursuit of material and spiritual gets higher and higher, the packaging of products has correspondingly higher requirements, when people buy products, not only look at the beauty of the packaging, but also consider a variety of other functions. It is because of the continuous improvement of people's pursuit of product packaging, many new packaging materials continue to be applied to product packaging.
Why we develop biodegradable materials
Synthetic polymer materials have the advantages of light weight, high strength, good chemical stability and low price, with steel, wood, cement has become the four pillars of the national economy, is widely used in product packaging. However, a large amount of waste after its use is increasing day by day, becoming a source of white pollution, serious harm to the environment, resulting in water and soil pollution, harm to human survival and health, to human survival environment caused a negative impact can not be ignored.
In addition, the production of synthetic polymer materials -- the raw material of petroleum is always exhausted one day, so it is urgent to find new environmentally friendly materials, the development of non-petroleum based polymers, and biodegradable materials is an effective way to solve this problem.
Definition of biodegradable materials
Biodegradable materials, also known as "green ecological materials", refer to materials that can degrade under the action of soil microorganisms and enzymes. Specifically, it means that under certain conditions, it can lead to biodegradation of polymer materials under the action of bacteria, mold, algae and other natural microorganisms.
Ideal degradation mechanism
The ideal biodegradable material is a kind of polymer material with excellent performance, which can be completely decomposed by environmental microorganisms after waste, and finally converted into CO2 and H2O, which becomes a part of carbon cycle in nature.
