Packaging, Food Processing and Labeling Exhibition Propak Africa, the definitive Packaging and Food Processing exhibition, provides an exciting forum for trading, sourcing of products and education – giving buyers leading-edge information on global trends, advancements in technology, product development and market updates.  The exhibition also provides an ideal platform for local and international exhibitors to network and exchange ideas.   Although the basic function of packaging is to preserve and protect the pack contents, packaging - particularly in the retail market - has become a fascinating marketing tool that is used to promote and sell products, moving them from shelf-to-trolley.  Innovative packaging design keeps products one-step ahead by creating a practical protective pack with a visual identity that communicates the right message to its consumer.   Sustainability has also quickly become a "mainstream" issue. Climate change, greenhouse gases, water and energy usage are all issues provoking concern about the sustainability of our lifestyles. While packaging is not a major focus of debate, it is inevitably being affected by it and industry is addressing the issues surrounding this concern.
