Biopolymer for FoodPackaging

In recent times the market price of petroleum products and oils has increased. These facts have helped to raise interest in biopolymers and in particular biodegradable
biopolymers. Biodegradable plastics and polymers were first introduced in the 1980s. There are many sources of biodegradable polymers, from synthetic to natural polymers. Natural polymers are available in large quantities from renewable sources, while synthetic polymers are produced from nonrenewable petroleum resources(Vroman & Tighzert, 2009).
These biopolymers are large macromolecules composed of single, repeating monomer units. They are of high molecular weight, and their material characteristics vary according to the nature of their monomer chemistry. Agriculture offers a broad range of commodities including forest, plant/crop, and
farm and marine animals, which have many uses. Plant-based materials have been used traditionally for food and feed and are increasingly being used in pharmaceuticals and nutraceuticals.
