Disposable supplies in the areaPolylactide absolutely harmless to human body characteristics make polylactic acid in disposable tableware, disposable food packaging materials and other supplies in the area has a unique advantage. It can also completely biodegradable meet the world, especially the European Union, the United States and Japan, the high demand for environmental protection. However, the use of polylactic acid material being processed does not exist disposable tableware temperature, oil and other defects. This resulted in significantly reducing the effectiveness of its functions, as well as in transit cutlery deformation, brittle material, resulting in a large number of defects. However, through the technical development, the market has been modified Zinc lactate that can overcome the shortcomings of the original grain, some even heat resistance up to 120 degrees, can be used for microwave equipment material.
Biomedical field
Bio-pharmaceutical industry is the first to carry out polylactide application areas. Polylactic acid on human security can be highly absorbed by tissue, combined with its excellent physical and mechanical properties, can also be applied in the biomedical field, such as magnessium lactate infusion set, to avoid demolition-type surgical sutures, drug relief package agents, artificial fractures fixation materials, tissue repair materials, such as artificial skin. High molecular weight polylactic acid has a very high mechanical properties, in Europe and other countries have been used instead of stainless steel, as a new type of orthopedic fixation materials such as bone screws, bone plates are heavily used, which can be absorbed by the body metabolism characteristics make patients from secondary pain of surgery. Its technology and high added value, the medical industry, the development prospects of polymer materials.
