Lime essential oil (LEO) has the potential to be incorporated into a film. Biodegradable polylactic acid (PLA) has shown potential in packaging applications. In this study, Lime extraction was carried out using a simple distillation method, and solvent casting methods were used to form the films. FT-IR result shows that the PLA primary functional group was visible at the frequency region of 495-560 cm-1 and 1740-1750 cm-1. With the addition of polyethylene glycol (PEG) and lime essential oil, the composite shows improvement in thermal stability. Even after being heated to 500 °C, none of the three samples completely disintegrated after being given lime essential oil as an additive.
