Abstract:
Petroleum-based films have contributed immensely to various environmental issues. Developing green-based
films from carbohydrate polymers is crucial for addressing the harms encountered. However, some limitations
exist on their property, processibility, and applicability that prohibit their processing for further developments.
This review discusses the potential carbohydrate polymers and their sources, film preparation methods, such as
solvent-casting, tape-casting, extrusion, and thermo-mechanical compressions for green-based films using
various biological polymers with their merits and demerits. Research outcomes revealed that the essential
characteristics improvement achieved by incorporating different metallic nanoparticles has significantly
reformed the properties of biofilms, including crystallization, mechanical stability, thermal stability, barrier
function, and antimicrobial activity. The property-enhanced bio-based films made with nanoparticles are
potentially interested in replacing fossil-based films in various areas, including food-packaging applications. The
review paves a new way for the commercial use of numerous carbohydrate polymers to help maintain a sus tainable green environment.
