Evidence shows TTIs and gas-sensing labels deliver the most near-term operational value for cold-chain auditing, while antimicrobial films extend shelf life with migration and sensory trade-offs. Pathogen-focused labels achieve lab-level sensitivity but remain limited by matrix effects and workflow constraints, suggesting targeted use at critical control points. Techno-economic and life-cycle reasoning indicate benefits are strongest when waste reductions approach or exceed ~10%, and when deployment is integrated with HACCP and GS1-based traceability. Adoption hinges on calibration transfer, food-contact safety, and data-governance compliance (EU 1935/2004; 450/2009). Overall, the work specifies when and how smart packaging measurably improves safety, quality, and waste outcomes in real supply chains.49ensmart packagingtime–temperature indicators (TTIs)gas sensorsAgricultural SciencesHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
