| Summary: | Human activities have already brought about changes to the ecological system
worldwide, thereby giving rise to global warming and pollution. These problems
have led to increased environmental degradation, which is destroying many things.
Many plastic packaging industries are trying to minimize their reliance on synthetic
materials in order to reduce toxicity levels [47]. Therefore, new environmental
guidelines are forcing the exploration of novel packaging materials that are compatible
with the environment. Such materials are currently being developed from
various natural resources, among which biopolymers are the most popular.
Biopolymers have many advantages compared to petroleum-based plastics in terms
of performance, processability, and biodegradability [82]. There are several types of
biopolymer matrices including polylactic acid (PLA), polyvinyl alcohol (PVA),
polyhydroxy butyrate (PHB) and starch-based polymers. The poor gas and water
barrier properties, unstable mechanical properties and weak resistivity of plastics
have limited their use in various applications [55]. Therefore, to improve their
mechanical and barrier properties, and to impart novel features to them, biopolymers
are reinforced with various nanofillers for the development of
nanocomposites. |
