Patent Analysis and Trends Related to 2D Nanomaterials for Active Food Packaging

Active food packaging technology encompasses systems that incorporate active substances into the polymeric matrix. The embedded components exhibit antimicrobial, antifungal, and antioxidant properties and are able to absorb or reduce oxygen, carbon dioxide or ethylene, thereby enhancing the quality and safety of food products. The utilization of 2D nanomaterials, such as graphene, has facilitated the advent of novel avenues for the advancement of active packaging (AP). The integration of these materials with polymers has the potential to enhance the barrier, thermal, and mechanical properties of packaging materials. The objective of this paper is to provide a comprehensive overview of patented two-dimensional materials in the field of active packaging.
