Bio-nano composites are nano composites including a naturally occurring polymer in mix with an inorganic moiety, and appearing no less than one measurement on the nanometer scale. This review presents the most commonly methods of bio- nanoparticles preparation in food packaging, the significant changes they cause in the properties of packaging material, and the commercially available nano-based materials. Those materials are ecofrindly and biodegradable advantages over petroleum products. Bio nanocomposite has good mechanical, barrier, optical, thermal, and other functional properties. It contains especial biomaterials and nano particles. The basic Synthesizing techniques of bio nano composites are in situ polymerization, solution casting, and melt processing. Spectroscopic techniques including Fourier transform infrared spectroscopy, X-ray diffraction, Raman spectroscopy, scanning electron microscopy, transmission electron microscopy, are the most used to characterize the functional properties and the surface structure of bio nanocomposite materials. Bio- nano composites are a smart food packaging whereby they can perceive property of the packaged food such as microbial contamination and uses some mechanism to register and convey information about the quality or safety of the food. Bio-nanocomposite materials for food packaging are important not only to reduce environmental problem but also to improve the functions of the food packaging materials.
