A REVIEW ON PVA BASED BIODEGRADABLE FILMS: A NEW HOPE FOR PLASTIC POLLUTION REMEDIATION
With the progress of modern science, people have started paying attention to degradable film. Biodegradable film not only has the function and characteristics of traditional synthetic polymers, but also it will revert to environment. These film attains the purpose of protecting the environment by using degradable materials such as agar, carrageenan, chitosan, gelatin, sodium alginate, etc. Polyvinyl Alcohol (PVA) is a water-soluble semi-synthetic polymer. This hygroscopic nature of PVA adds a new dimension to the world of biodegradable films. In this modern civilization with the growing population, the need of packaging material is huge in every sector. Long term use of synthetic packaging is harmful for health as well as has an adverse effect on nature due to difficulty in disposal of garbage. So this paper conducts a clear exposition how PVA has open a wide wing to preserve our ecology accompanied by the other natural biopolymers.
