Advantages and Disadvantages of PLA Bioplastics News
PLA can be processed via extrusion, injection molding, casting, blown film, thermoforming, and fiber spinning. PLA is made by the polymerisation of lactic acid or lactide. Lactic acid is produced through bacterial fermentation of a carbohydrate /sugars coming from plants such as corn, sugar cane, sugar beet, cassava
