Abstract

The growing demand for sustainable packaging has accelerated the development of biodegradable and environmentally friendly materials as alternatives to conventional plastics. Among the various strategies explored, the development of bioplastic films from renewable and natural resources offers a promising solution for reducing plastic pollution, particularly in the packaging sector. This study focuses on the formulation and optimization of a bioplastic film using natural polymers- starch and carrageenan-known for their biodegradability, film-forming ability, and availability. The primary objective is to produce a film with enhanced mechanical integrity, thermal stability, and functional properties such as water solubility, making it suitable for packaging applications. Bioplastic films were prepared using the solution casting method, where starch and carrageenan were blended in varying ratios along with glycerol as a plasticizer. The films underwent controlled drying and were characterized using multiple techniques. Thermogravimetric Analysis (TGA) evaluated thermal stability, while Fourier Transform Infrared Spectroscopy (FTIR) analyzed molecular interactions. Addition ally, water solubility tests, biodegradability assessments, and mechanical tests were conducted to determine the performance of the films. The results indicated that increasing carrageenan content improved the mechanical properties and water solubility of the films, which are beneficial for packaging applications. However, this enhancement was accompanied by a reduction in thermal stability and biodegradability. These findings highlight the potential of starch-carrageenan based films as sustainable packaging materials and provides a foundation for further research in biodegradable polymer blends.
