Few Polymers after use tend to degrade by bacterial decomposition and result in a natural by-product such as gas, water, biomass, and inorganic salts. They are natural and can be made synthetically. they consist of ester, amide and ether and other functional groups. Artificially synthesized polymers by condensation reactions, and metal catalysts. Food packaging can be done in an alternative way which is environment-friendly, non-toxic and low cost. They have distinct uses and hence abides in all the fields from agriculture to engineering. They take a major place in drug delivery and nanomedicine. The pill en-capsules inside the polymer coated shield and sent inside the body. As the polymer emits the medicine, the polymer naturally degrades into natural by-product and it is excreted.
