This document discusses sustainability transitions in food packaging from the perspective of companies. It defines sustainability transitions as long-term transformations to more sustainable production and consumption. For food packaging, this involves innovations that meet changing societal values around policy, media, consumer and supply chain demands. However, barriers like complexity, uncertainty and competition exist. Collaboration is seen as key to overcoming barriers by creating shared understanding and multi-party problem solving. Currently, companies collaborate through associations, but different roles in relation to change exist, from maintaining the status quo to facilitating change. Ongoing and upcoming facilitated dialogues and the PackageHeroes transition arena aim to further cross-system collaboration for deciding concrete transition pathways.
