Biodegradable sago starch/polyvinyl alcohol (PVA) films were developed using various percentage of silica. The effect of silica as filler on the mechanical properties, water resistance and degradation behaviour were investigated. Results showed that the 2.0 wt% of silica content in sago starch/PVA films exhibit higher tensile strength but lower elongation at break than films without additional silica. Water absorption and water vapour transmission were decreased with the addition of silica content. Biodegradability test revealed that the increment of silica content reduces the degradation process of sago starch/PVA films.
