The 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 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 min. showing a good result in morphological surface analysis. Moreover, the cellulose nanocomposite film exhibited as a good food packaging material to negate the microbes growth in food.

This research was aimed to manufacture polyvinyl alcohol (PVA)/cellulose nanofiber (CNF) nanocomposite which was isolated from oil palm empty fruit bunches (OPEFB) through steam explosion method combined with a hydrolysis process involving HCl 10%. The isolation process was performed in 2 steps; α-cellulose isolation from empty fruit bunches fibers and then cellulose nanofiber isolation from α-cellulose which was hydrolyzed with acid using ultrasonicator and homogenized in rotational speed of 8000 rpm. The functional group and morphology of nanofibres cellulose were characterized. FT-IR spectrum resulted an absorptions for C-O-C group at wavelength of 1059.99 cm-1 which indicated a glycoside bond. Then, C-H group at 2900.94 cm-1 and O-H group at 3348.62 cm-1 were revealed to indicate the cellulose nanofiber. Moreover, TEM was used for morphological analysis and showing a decrease in fibres diameters after experiencing a chemical-mechanical treatment which lead to nanofibres with final diameter size of 20-30 nm. PVA/CNF nanocomposite with the percentage ratio of 80:20 gave a tensile strength of 17.41 Mpa and Modulus Young of 0.9 Gpa. Finally, the product was also morphologically analyzed with SEM and indicating an even distribution on the PVA surface.
