Introduction The increasing interest in alternative and durable packaging materials research over the last few years is due to the concern of environmental safety of synthetic packaging and coating materials as well as consumer demands for high quality and long shelf life products. Different renewable bio polymers − processed by different methods − have been used for packaging applications Cellulose-based materials are considered the most common renewable bio-based packaging materials e.g., paper and paperboard. Due to its hydrophilic and porosity, paper loses its physical and mechanical properties because of water absorption from the environment or from the packaged materials, especially in case of food packaging. Coating with polyolefins, aluminum foil and plastics improve the barrier properties to water vapor, oxygen and aroma but on the other hand, the obtained material loses its biodegradability and recyclability due to the addition of synthetic polymer layers. Bio polymers can be considered as a promising alternative to synthetic polymers. Recently, the use of nanotechnology to develop bio polymer composites with addition of nano fillers (derived from natural resources) has opened new possibilities for∗
