摘要

Food packaging materials (FPM) based on nanotechnology are gaining popularity nowadays, due to increased consumer awareness. Nano-ranged oxides are shiny oxide-based nanostructures that are transparent and have excellent antimicrobial characteristics. There are various oxides present on Earth, such as copper oxide, iron oxide, titanium dioxide, and zinc oxide, but nano alumina (Al2O3, or aluminum oxide) is the most commonly used oxide for formulating food packaging materials (FPM). Nano-oxide-based materials for food packaging offer many additional benefits, overcoming the limitations of conventional FPM. The inclusion of nano-oxides improves many properties of packaging materials, such as barrier performance, tensile strength, thermal stability, and optical properties.

Since fruits and vegetables are highly sensitive to oxygen and water permeability, their quality degrades over time. Nanotechnology in food packaging plays a crucial role in addressing this issue. Metal oxide-based nanoparticles reduce the microbial load on food products and enhance the development of active food packaging systems. This article discusses the formulation techniques for aluminum oxide-based nanoparticles and their various properties. In addition, the wettability of plastics coated with nano oxides is also discussed.
