Biodegradable garbage bag research on biodegradable packaging materials has made great contributions to the protection of the world environment
The plastic packaging materials in today's society cause serious "white pollution", which destroys the ecological environment and causes waste of resources. Biodegradable food bag, which is made from natural degradable materials such as straw starch, cellulose, protein and chitin, has rich source, no pollution and easy decomposition, and has broad application prospects.
Plastic products have the characteristics of airtight, impervious to water, acid and alkali, light weight, high strength, durability and low price, thus becoming the most widely used material in the packaging industry. In addition to the production enterprises, retailers, farmers' markets and even street food stalls do not use plastic bags and foam plastic boxes as the main packaging. About half of these products are disposed of in the environment and typically take 200 years to degrade. Another type of packaging material that is used in large quantities is paper-plastic products. Most of these paper-plastic products are discarded in the environment after use, and it takes 80 years to degrade even under the action of microorganisms. The serious consequences of such refractory plastic products being discarded in the environment are enormous waste of resources and environmental pollution.
In response to this situation, Qingdao fullsun biotechnology company put forward the concept of "environmental packaging", which must not only pursue good performance, but also profoundly recognize the limited nature of natural resources and minimize waste emissions. The extraction, preparation, and use of materials until the entire process of disposal and regeneration minimizes the impact on the environment. It is a material that takes into account environmental, ecological and resource factors. Biodegradable shopping bag is a material that saves resources, reduces pollution, has little ecological impact, is reusable, and is degradable.
In recent years, countries around the world have developed some degradable plastics and biomaterials, which have greatly promoted the development of packaging materials industry in various countries. Biodegradable garbage bag (mainly adding starch, cellulose, photosensitizer, biodegradant and other additives to plastics) has the disadvantages of consuming a large amount of food, eliminating visual pollution, and the presence of plastic micro-materials in the soil. The degradation rate is slow and cannot be recycled in time. Therefore, the application prospects of degradable plastics have limitations, and the most potential for development is biological packaging materials.
As a natural polymer material of Biodegradable tableware, starch is rich in source and cheap. Decomposed into glucose under the action of microorganisms, and finally metabolized into water and carbon dioxide, is an inexhaustible renewable resource.
Natural plant fiber is also a renewable resource that meets the requirements of sustainable development. It is the most abundant carbohydrate on earth. It can be degraded by microbial degrading enzymes in nature and taken up as a plant or microbial nutrient source.
In recent years, Biodegradable straw has become a hot spot in the research and development of starch-based materials due to the biodegradation or soluble degradation of modified starch. The starch-based material can be used as a package for fried snack foods, a disposable food bag, and an outer film for paper packaging.
With the strengthening of environmental awareness among the contemporary people, in the face of the increasingly serious "white pollution" and the depletion of traditional resources, research and development of new packaging materials is of great significance. Biodegradable food bag bio-packaging materials showcased a new and comprehensive field of science from the fields of environmental science, ecological science and polymer science, and is an important field in the material field of the new century. At present, bio-packaging materials are limited to their high cost. With the development of economy, technology and culture, bio-packaging materials will be further developed.
