Packaging is one element that can support and promote improvements and innovations in sustainable management of supply chains. This multifunctional vision has brought about the approach "sustainable packaging logistics" (SPL), which refers to the integration of packaging design, logistics management and new product development. The main aim of this paper is twofold. Firstly, to characterise the main aspects associated with SPL as a preliminary step towards constructing a conceptual model that can be validated in a quantitative way. Secondly, to carry out an exploratory study in the Spanish toy manufacturing sector in order to identify whether SPL deployment promotes changes and innovations in packaging that can lead to improved sustainability. The literature review was conducted via content analysis, and the methodology used to carry out empirical analysis was an electronic questionnaire dealing with aspects of SPL. The number of toy manufacturers participating in the study was 70. The results analysis indicates that further development of the main aspects of SPL actively contributes to better sustainable performance in almost all items considered in the study. The SPL approach is considered particularly innovative, because there is a scarcity of literature that deals jointly with packaging, logistics and sustainability from an empirical standpoint, rather than just the analysis of case studies.
