Food packaging has a crucial function in the modern food industry. New food packagingtechnologies seek to meet consumers and industrial?s demands. Changes related tofood production, sale practices and consumers´ lifestyles, along with environmentalawareness and the advance in new areas of knowledge (such as nanotechnology orbiotechnology), act as driving forces to develop smart packages that can extend foodshelf-life, keeping and supervising their innocuousness and quality and also takingcare of the environment. This review describes the main concepts and types of activeand intelligent food packaging, focusing on recent progress and new trends usingbiodegradable and biobased polymers. Numerous studies show the great possibilitiesof these materials. Future research needs to focus on some important aspects suchas possibilities to scale-up, costs, regulatory aspects, and consumers? acceptance, tomake these systems commercially viable.
