Novel Coir/Chitosan Composites for Packaging Applications

Abstract

Composites are a popular choice in the current industrial scenario for a number of reasons and their extensive use poses serious environmental issues. This prompts us to explore the possibilities of completely natural composites that can strike a balance between performance and ease of disposal. In this regard, a novel “Green” composite material constituting Chitosan as a natural matrix material in conjunction with other natural reinforcements (Coir) is explored. Preliminary experimentation on composite fabrication was carried out to obtain laminated coupons. Physical characteristics such as density and finish quality were analyzed and used to optimise process parameters. Test coupons were prepared and evaluated for tensile properties. Further various food packages were produced and tested for their feasibility. This article presents an early investigation into the viability and effectiveness of chitosan as a natural matrix for the production of entirely natural composites and their appropriateness in packaging applications.
