This  research  investigated  the  potential  of  biopolymer-additive  films  for  food preservation. Three biopolymers, namely chitosan (CS), gelatin (GL) and methylcellulose (MC) were  used in this research. Ascorbic acid (AA), tannic acid (TA), banana leaf essential oil (BA), clove  essential oil (CL), turmeric extract (TU) and chamomile extract (CH) were used as natural additive.  This research is divided into five main studies, namely synthesis, characterisation, antimicrobial  activity, food preservation and biodegradation. The main scientific instruments used in this study  were Fourier transform infrared (FTIR) spectrometer, scanning electron microscope (SEM), universal  testing machine, water vapour permeability (WVP) analyser, oxygen permeability (OP) analyser,  ultraviolet-visible (UV-Vis) spectrophotometer and thermogravimetric analyser (TGA). The bacteria  used for antimicrobial activity were Staphylococcus aureus (Gram-positive) and Escherichia c.....
