This research aimed to develop paper from oil palm empty fruit bunch (Fb), oil palm mesocarp (M), and paper mulberry (P), with chitosan coating, to be used as single-use paper bag for dry food products. The optimal conditions for pulp preparation of Fb, M, and P fibers were cooking in 30, 25, and 15% NaOH solution at 170, 170, and 100°C, for 3 hours, respectively. The optimal H2O2 concentrations for bleaching of Fb, M, and P pulps were 40%, 40%, and 0.2% respectively. The obtained pulps were then used to prepared papers with the basis weight of 109 g/m2. The papers consisted of Fb, M, and P pulps at ratios of 70:0:30 (FbP), 0:70:30 (MP), 35:35:30 (FbMP). It was found that FbP paper showed superior physical and/or mechanical characteristics than those of MP and FbMP. FbP papers were then applied with chitosan solutions (0.2-0.6%) to further improving their mechanical properties and reducing their water absorption characteristics. The optimal concentration of chitosan was 0.4%. This study showed that all three types of pulps could be used to produce papers that had equal or superior mechanical- and water adsorption properties as compared to commercially available paper bags made from wood pulp.
