Although biodegradable polymers like cellulose based polymeric films have been in existence as the best materials
for preparation of packaging films [14, 15] their hydrophilic nature has put several restrictions on its usage. On the
other hand, polyethylene based films show excellent mechanical strength, hydrophobic nature and moisture barrier properties which are some essential features for a good packaging film. It should also be noted here that these
polymeric materials cannot be functionalized, which restricts its usage.
