Nanomaterials Utilized in Food Packaging: State-of-the-Art

Abstract

Nanotechnology has been applied to develop materials with incomparable characteristics to produce innovative products in various fields of the industry. The use of nanomaterials with their unique properties is due to the advantages of their nanoscales. The physical and chemical properties of nanoscale materials differ significantly from those of their micro- and macroscopic equivalents, providing significant benefits for packaging materials. In recent years, the use of nanotechnology in packaging has been addressed suggesting a wide range of potential commercial uses. According to a recent market analysis, the usage of nanotechnology in packaging will grow in the next years, especially in applications like active, intelligent, and smart packaging. However, larger-scale adoption would involve consideration of their possible implications on both consumers and the environment. On the other hand, great interest in using nanotechnology by industrial stakeholders due to the innovative and economic benefits requires a well understanding of the potential impact on environment, safety and health and addressing relevant regulation and legislations to minimize the risks. Despite the interest in nanomaterials and their benefits in the food packaging industry, their application has not been as prevalent as one might assume. Various roadblocks, such as information shortages in the area of toxicity and safety evaluation, have hampered a more widespread application. Nevertheless, food packaging industry is a growing sector and requires more sustainable materials and implementations to diminish food waste. In this aspect, nanoscaled materials are promising in the future of packaging industry.
