While noted improvements have taken place in the area of ceramics and metals, it is the field of polymers that has experienced an explosion in progress. The selection of the best packaging material is a crucial point for food market, because it needs to be versatile enough to withstand handling process forces maintaining physical and chemical integrity and suitable for barrier properties to several gases used in MAP techniques (e. Coefficient of Friction (COF) A packaging film’s “coefficient of friction” (COF) provides a relative indication of frictional characteristics. 12 Nanocellulose materials, including cellulose nanocrystals (CNC), nanofibrillated cellulose (NFC), and bacterial nanocellulose13 (BNC), have unique properties with the potential to dramatically 14 impact many commercial markets including. Such a material iselastic accordingtothedescription ofelasticity given earlier (immediate response,fullrecovery), andit is also linear in its relation between stress and strain (or equivalently, force and deformation). Sustainable economy utilizes mainly bio-mass derived raw materials for high-volume applications, such as packaging [1]. In summary, PLA in a variety of forms has been shown to be an excellent material for packaging food products. Some applications include food containers, soil retention sheeting, agriculture film, waste bags [16] and the use as packaging material in general [31].
