The effect of cellulose from oil palm trunk (OPT) concentrations (1, 3, 5, and 7 wt %), which were treated various times with urea mixed in NaOH aqueous solution on fabricating cellulose film, were studied. The results showed cellulose from OPT film was successfully prepared through cellulose was dissolved in 7wt% NaOH/12wt% urea aqueous solution at 4°C. The function group was evaluated by FTIR, whereas the physical properties were observed by a camera. The photographs of cellulose film concluded that 5wt% cellulose from OPT had a smoother surface than other ratios. The FTIR result showed that the vibration peak confirmed that cellulose from OPT successfully produced cellulose film. The mechanical properties result showed that urea mixed into cellulose/NaOH suspension after 24 hr presented better mechanical properties than urea mixed immediately. This research provided a friendly environmental system for the preparation of the packaging films.
