A great number of scientific studies have shown the role of packaging design in shaping consumer reactions. Among the different design elements, packaging materials can have a significant influence. This was the focus of a neuroscience-based study conducted by Mind Insights on the sparkling water category. The study explored how different packaging materials (glass, PET or aluminium) can shape consumers’ perceptions and beliefs, from quality to sensory pleasure, eco-responsibility, product value, desirability and even health concerns.
