What are the applications of pla in other fields?
Application in daily necessities
Polylactic acid can also be used as paper substitutes, paper plastic film, packaging film, food containers, garbage bags, cosmetics and other additives. One company in Japan uses ordinary plastic injection molding equipment to process various tableware, such as cups, dishes, bowls, chopsticks, basins and other daily necessities. For the first time, PLA was made into disposable lunch boxes and food packaging bags in Fuzhou, China.
Polylactic acid plastics can also be used as water retaining materials for forestry, aquatic products and soil and desert greening. Kou Shijun et got biodegradable composite fiber was prepared by composite spinning of PLA and polyglycolic acid.
Application in packaging industry
In Europe and North America, polylactic acid packaging materials are used for supermarket product packaging. PLA has the basic characteristics of biodegradable plastics, which can be safely disposed after use without any harmful substances. In addition, PLA has the same printing performance as traditional film, so PLA has a broad application prospect in the field of packaging materials.
The application of clothing field in clothing
It can be made into yarn, fabric, woven fabric, nonwovens, etc. it has dyeability and biocompatibility. The fabric has silky luster and handle, excellent drapability and good smoothness. It does not irritate the skin. It is healthy and comfortable to wear. It is especially suitable for underwear and sportswear
Application prospect of polylactic acid
PLA materials with their excellent properties make people's enthusiasm for their research for a long time, and all kinds of research continue to deepen. Its potential value is beyond doubt, but its shortcomings also greatly hinder its large-scale application. In view of the existing problems, the future research work will be carried out from the following aspects: continue to improve the synthesis process conditions of PLA, produce high molecular weight and ultra-high molecular weight polymers, simplify and shorten the process flow, and reduce the production cost of materials. As a biomedical polymer, new polylactic acid has good biocompatibility, biodegradability and bioabsorption. It has played a very important role in surgical suture, medical fixation materials, sanitary products and other medical fields. Because of its good degradation performance, it is widely used in packaging, agriculture and fast consumer goods. Polylactic acid, as a substitute for petroleum based plastics and chemical fibers, will have more extensive application potential and market prospects.
It is believed that in the near future, with the joint efforts of researchers at home and abroad, PLA and its modification will be promoted The products will show a broad application prospect in biomedicine.
