Packaging has always served an important role in the food supply chain. In mature countries around the world, the majority of foodstuffs are packaged—approximately 90%, and food packaging is a major growth area in emerging nations. Packaging provides protection for products (a barrier against humidity, gases, a protection against flavors/odors or light), it also provides product information for the consumer and helps to establish brand identity. In these tough economic times, the food packaging market is one of the few growth areas. However, it is not without its challenges.
