Introduction: Food packaging materials

Food packaging is not only indispensable in the distribution chain but is designed to prevent the spoilage of food products throughout the supply chain. Diversity in food composition and product structure in fresh and processed food products demands unique packaging solutions for each product category. However, the primary function of packaging remains similar in order to preserve the freshness as well as to prevent spoilage and pathogenicity and to extend the shelf life. Before we proceed to the packaging material properties, it would be appropriate to review basic functions of food packaging-that is, protection, containment, communication, and convenience (Figure 1.1) (Wani et al., 2014).
