The huge environmental impact associated with the use of conventional packaging materials, like polyethylene, has led to the renewed interest in alternative ways of food packaging. Recently, green polymer technology, which involves the application of renewable packaging materials made from biodegradable resources like starch, has been the subject of discussion among stakeholders in food processing and storage. This review was carried out to investigate the mechanical, thermal, barrier and structural properties of biodegradable nanocomposite packaging materials made from starch. Emphasis was given to the application of the starch-based biodegradable packaging materials in fruits and vegetables packaging. The prospect of the new materials in terms of strength, barrier to moisture and oxygen, morphology and thermal stability, with regard to the inclusion of nanoparticles, for this application was highlighted. The information provided will help address the environmental challenges often posed by the conventional materials while at the same time improve the post harvest storage stability of fruits and vegetables through packaging.
