Abstract: Novel biocomposite emulsion is the alternative to use as coating materials for paper to improve its moisture barrier properties and degradability of product in normal environment (20-25°C, 60%RH). In this study, the composite based-emulsion coating was prepared from nanofibrillated cellulose (NFC) that produced from destarched cassava pulp and rice bran wax (RBW) and then coated on paper surface by wet film applicator rod coating. The effect of NFC concentration and RBW solid content on moisture barrier and mechanical properties. Coated paper with 1wt% of NFC and 90wt % of RBW solid content in coating layer showed were reduced water vapor transmission rate (WVTR) by 21.92% reduction and also increased contact angle from 93.54±5.14° of uncoated paper to 102.63±0.75° that indicated moisture barrier property was improved hydrophobicity by RBW-NFC composite emulsion coating. The lipid addition was also the important effect on the mechanical properties resulting to weak and brittle coated paper. The surface morphology of emulsion coated paper was examined by using scanning electron microscopy (SEM) to feature and explicate the hydrophobicity and the efficiency of coating material. This study is suitable for further investigation to verify green-based emulsion paper coater that could be used to produce potential packaging with enhanced moisture barrier property and assigned as sustainable materials.
