Milad Rouhi, the project manager, referred to edible films as one of the most important components in biodegradable packaging.

�Synthetic polymer-based biofilms are usually stronger, more maintainable and have more functions than the natural type.�

He went on to say, �Among synthetic polymers, the hydrophilic types, due to the use of polar solvents, are cheaper and less hazardous, and create less environmental pollution.�

�Furthermore, these types of polymers are usually edible and have higher biodegradability,� he added.

�In this study, new methods have been introduced for improving the performance and efficiency of these polymers in food packaging through the use of nano-crystalline cellulose,� he said.

Adding a specific amount of nano-crystalline cellulose and correction of the polymer structure will cause significant improvement in mechanical, thermal and durability properties of the biofilm, he added.

�The correction of the polymer structure was done via a simple and cheap method,� he said.

�Furthermore, within the structure of the polymer a color with antioxidant properties has been used which reduces chemical corruption of the packaged food.�
