PLA belongs to the family of aliphatic polyesters derived from α-hydroxy acids. The basic building block of PLA, lactic acid, (2-hydroxy propionic acid), can exist in optically active

-enantiomers, which can be produced by carbohydrate fermentation or chemical synthesis. Depending on the proportion of the enantiomers, PLA of with variable material properties can be derived. This allows the production of a wide spectrum of PLA polymers to match performance requirements.
