Plastics are used for packaging material because of their inexpensive, flexible, strong and corrosion-resistant material. Plastic is not
degraded in the environment by microorganisms in the long term. In-vitro degradation of synthetic plastic is a time-consuming
process (Schink et al. 1992) but these plastics are polluted environment. So, we need an alternative. Bioplastic is alternative for the
synthetic plastic.
The natural polymers are derived from animal, marine, and agricultural sources, which include the polysaccharides, such as starch,
cellulose, and chitin. Plant and animal extracted proteins (casein, collagen, gelatin) and lipids including cross linked triglycerides.
By nature most of these polymers are hydrophilic and crystalline in nature, which create several problems while processing in moist
food packaging.
