Biodegradable t-shirt bag supplier to share with you: Biodegradable material, as a naturally degradable material, has played a unique role in environmental protection, and its research and development have been rapidly developed and considered to be It is an effective solution to "white pollution".
Biodegradable materials are polymer materials that can undergo chemical, biological or physical degradation or enzymatic hydrolysis under the action of microorganisms existing in nature such as bacteria, fungi and algae.
The most ideal biodegradable garbage bags are obtained from renewable resources and can be reused by organisms after degradation. The product is preferably carbon dioxide and water, so that the production and use of this material are brought into the natural world. cycle.
Application areas: packaging materials, drug carriers, tissue engineering ...
1. Polylactic acid (PLA): PLA is non-toxic and non-irritating, good biocompatibility, high strength, good processability, and biodegradable. Sheets, fibers, and films are made by thermoforming, spinning After secondary processing such as silk, it is widely used in packaging, textile and medical fields. Its waste can be decomposed into water and carbon dioxide by microorganisms.
2. Polyhydroxy fatty acid ester (PHA): PHA is a kind of intracellular polyester synthesized by many microorganisms. It is a natural high-molecular biomaterial with good biocompatibility, biodegradability and plastic. Thermal processing properties, can be used as biomedical materials and biodegradable packaging materials.
3. Polybutylene succinate (PBS): PBS has excellent comprehensive performance, reasonable cost performance, and is widely used in packaging, tableware, cosmetic bottles and pharmaceutical bottles, disposable medical supplies, agricultural films, pesticides and fertilizers. Release materials, biomedical polymer materials and other fields.
4. Polycaprolactone (PCL): In addition to the characteristics of easy processing of thermoplastics, PCL also has the characteristics of biodegradability, biocompatibility, and temperature-controlled memory. It is mainly used as a controlled-release drug carrier. Medical materials such as fully degradable plastic surgical sutures.
Industry development goals
The "Guide to the Development of New Materials Industry" mentioned in the urgently needed new materials to break through the key application areas, the development of green building materials and new refractories and biodegradable materials.
"Made in China 2025" mentioned that the localization of important raw materials, large-scale support for medical consumables, osmotic membranes, degradable devices and other products, with an annual output scale of 3 billion yuan.
