An Overview of Nanotechnology-Based Innovations in Food Packaging

Packaging of the food items is the most important and inevitable level of the food supply chain because the higher packaging leads to longer sturdiness, shelf life, and renovation of mechanical, physical, chemical, and physicochemical properties of food products. Nanotechnology-based food packaging is a new and novel technique of packaging method, which relies upon nanomaterials, has grown to be one of the fastest-growing elements in nanotechnology, and denotes critical opportunity and advancements. An essential nano-based food packaging material needs to have gas and moisture permeability integrated with strength and biodegradability. Different components of nanotechnology-based techniques used in food packaging include nanocomposites, bio-nanocomposite films, nanoemulsions, nanostructures, nanolaminates, nanoclays, nanopolymers, and nanocoatings. There are different types of nanotechnology-based food packaging including active food packaging, smart/intelligent food packaging, improved packaging, bio-based packaging, modified atmospheric packaging, and oxygen scavenging packaging. Nanotechnology in food packaging substances confers many benefits over conventional packaging methods because they improve food quality and safety, inform 4 the consumers whether the diets are spoiled or not, renovate tears in packaging, and prolong the duration of storage of the food. Therefore, nanotechnology-based innovations are playing key roles in the modern food packaging industry.
