Food packaging and potential microplastics release

Food packaging systems, especially those reliant on fossil-based plastics, represent a significant source of pollution if not properly handled or disposed of. Recently, there has been increasing attention on the potential release of microplastics (MPs) from containers into food products and the consequent effects induced on human health through consumption. Therefore, this book chapter aims to provide an overview of current research on MPs production from plastic-based food packaging systems, emphasizing the main factors influencing their release. It also highlights the gaps that need to be addressed in terms of potential hazards to human health when exposed to foods contaminated with MPs. Finally, the possibility of reducing microplastic release from food packaging materials through a “green” approach is discussed, with the aim of positively impacting consumers' health.
