Poly(lactic acid) or polylactide (PLA) is a biodegradable thermoplastic derived from renewable resources such as corn starch, tapioca or sugar cane. PLA sheet is 100 percent biodegradable and compostable.
PLA is mainly used in the packaging industry for cups, bowls, bottles and straws. Other applications include disposable bags and trash liners as well as compostable agriculture films.
PLA is also an excellent choice for biomedical and pharmaceutical applications such as drug delivery systems and sutures because PLA is biodegradable, hydrolysable and generally recognized as safe.
