The all-cellulose nanocomposite as food packaging has been prepared from the isolated cellulose of corncobs waste. The cellulose in corncob powder was isolated through a standard isolation method with various acid and bases by the heating process. As many as 17.4 % of cellulose was successfully isolated and characterized via FTIR spectroscopy, TGA and TEM. Furthermore, the isolated cellulose was partially dissolved in DMAC/ LiCl 8 % and compressed at high temperature to produce the all-cellulose nanocomposite film. The isolated cellulose showed a similar functional group with the commercial cellulose, indicating the success of the isolation process. SEM analysis was conducted to several all-cellulose nanocomposites with various time of soaking. The best soaking time to perform was 60 minutes, showing a good result in morphological surface analysis. Moreover, the all-cellulose nanocomposite film exhibited as a good food packaging material to negate the microbes growth in food.
