Majority of materials employed for food packaging are non-biodegradable which do not meet increasing demands in society sustainability and environmental safety. Thus, numerous biopolymers have been exploited to develop biodegradable materials. Nonetheless, the usage has limited due poor mechanical barrier properties. These properties can be enhanced by adding reinforcing nano-sized compounds or fillers form composites. This article reviews variety types biopolymer filler used bio-nanocomposite
