Smart Packaging: Innovative Packaging in Pharmaceuticals

Smart packaging represents an advanced packaging approach developed to address challenges in the pharmaceutical, food, and cosmetic industries, including product safety, quality assurance, patient compliance, and supply chain traceability. This review outlines the evolution of smart packaging, its classifications, and emerging technological advancements. Smart packaging is broadly divided into two main categories: active packaging and intelligent packaging. Active packaging enhances shelf life and maintains freshness by regulating internal conditions—such as controlling oxygen and carbon dioxide levels, managing moisture, and inhibiting microbial growth. Intelligent packaging incorporates technologies including sensors, colorimetric indicators, barcodes, and RFID tags to monitor freshness, storage parameters, and product safety. Additionally, sustainable innovations such as biodegradable materials, edible packaging, and 3D-printed solutions are being investigated to reduce environmental impact. Despite its advantages, smart packaging faces limitations including high implementation costs, insufficient regulatory harmonization, and electronic waste concerns. Future advancements are expected to integrate Artificial Intelligence (AI), Machine Learning (ML), and the Internet of Things (IoT) to develop safer, more sustainable, and consumer-oriented packaging systems.
