Every year, millions of tons of plastic mix into the seas and oceans, harming the ecosystem and causing the death of thousands of living organisms. The uncontrollable growth of the problem has led researchers to seek alternative products that are compatible with nature. For this reason, research on the use of biodegradable polymers produced from natural sources instead of petroleum-based products is increasing day by day. Alginate is a biopolymer with countless application areas due to its ability to form hydrogels, the presence of hydroxyl and carboxylate groups in its structure, biocompatibility, biodegradability and water solubility. In addition, the fact that alginates can be easily modified makes this relatively cheap biopolymer very important for both the environment and the ecosystem. Sodium alginate is a highly preferred polymer, especially in food applications, and is used both as a thin film in food packaging and for coating fresh foods to extend their shelf life. In this study, alginate, which is a sustainable source and needed by many sectors, especially paper, textile, food and cosmetics, from macroalgae, was isolated according to the Haug and Larsen method and characterized comparatively with the commercial product. Physical (water swelling, solubility, light transmittance, rheological and mechanical properties) and chemical structure characterizations (Fourier Transform Infrared Spectroscopy and UV-Visible Spectroscopy) of thin films prepared with extracted sodium alginate and easily accessible and biodegradable polymers obtained from natural sources (carboxymethyl cellulose, hydroxy propyl guar, gelatin, etc.) were performed and their potential for use as food packaging was discussed
