How does polylactic acid come from?

Firstly, the crops are pretreated to extract starch, and then the starch is further processed,
Decompose these starches into glucose. Then add these glucose to specific bacterial strains for fermentation,
Obtaining high-purity lactic acid and then connecting one lactic acid molecule after another through polymerization reaction forms polylactic acid.
We will process and modify the polylactic acid we obtain, and it will transform from our common crops
Transformed into a lunch box in the hands of athletes. The polylactic acid lunch box used by our athletes is a great source of biomass.
Because polylactic acid is a polymer formed by the polymerization of lactic acid, its monomer is lactic acid, which is more colloquial
It's the lactic acid in the yogurt you drink. In fact, the lunch box used by athletes is what we usually eat, which is lactic acid,
So using this lunch box will not cause poisoning to the human body.
Polylactic acid is an acidic polymer that exhibits antibacterial activity against Candida albicans, Escherichia coli, and Staphylococcus aureus
Up to 95% or more. So polylactic acid has also been made into synthetic fiber materials, which can be degraded and can also prevent corrosion.
