In the food industry, packaging has always been a very important part of the product. It's primary function is to contain and protect food therein, ease storage and transportation and also to communicate and market the product.
With new regulation, packaging must also clearly indicate quality and composition requirements such as ingredients list, allergens and certifications attached to the product, depending on local, national and global regulatory requirements.
Economic downturn and harsh competition make food manufacturers focus on innovation. R&D teams are always thinking of new formula, new concept, new size etc. Innovation is the best way to differentiate, keep margins high and expand market shares. Product innovation is also about packaging.
