Evolution of Food Packaging and Its Effect on Human Food

Abstract

Packaging is an integral part of our food systems that has shown a continuous path of innovation. From ancient times to now, packaging has been a mode of containing food, protecting food, providing convenience to consumers, and being a means for manufacturers to communicate with consumers.

The evolution of packaging started from natural wood, clay, and animal materials and changed to modern-day materials such as paper, metals, and glass, as well as advanced materials such as synthetic polymers, biopolymers, and nanocomposites. It is now in a state where nanomaterials are being incorporated into food packaging as well. The
