Biodegradable Polymer Composite Films for Green Packaging Applications

Abstract

In present scenario, consumption of indispensable nonbiodegradable plastics has become a potential threat to the environment. Their use has been growing up at an alarming rate due to their low cost, easy manufacture, light weight, and water-resistant nature. Hence, we need to think for restricting the use of indispensable plastics and find some alternative to minimize the use of nonbiodegradable waste. Biodegradable polymer composites are composed of polymer and natural fiber. Natural fibers are used as a reinforcing agent in a polymer matrix for enhancing the mechanical property of the resultant composites. Many scientists have reported numerous preparation methods such as compression molding, hand layup, extrusion, injection molding, and solvent casting method to fulfil the industrial aspects as compared to synthetic plastics for green packaging application. Some strategies are also applied for enhancing the adhesion between polymer and natural fiber. After listing the numerous sustainable synthesizing methods, various testing methods such as water vapor transmission rate, water vapor permeability, optical characteristics test, thermal stability test, mechanical stability, and impact strength are presented in this chapter to check the suitability of green packaging film. © Springer Nature Switzerland AG 2021.
