This study examines the transition from linear to circular packaging, highlighting the role of smart packaging technologies in enhancing circular economy strategies. We explore the challenges and technological facilitators in adopting circular packaging through an embedded case study approach involving Scandinavian manufacturers. Our findings suggest that smart packaging, equipped with sensors and digital capabilities, helps address supply chain complexities and regulatory compliance issues. It also has the potential to improve consumer acceptance and foster collaboration among stakeholders. The paper underscores the potential of integrating smart technologies into packaging to accelerate sustainable practices within the CE framework.
