<p>Non-migratory active food packaging (NMA-FP) is driving a fundamental transformation in the field of food preservation. Unlike traditional "migratory" active packaging, where additives are directly released into food, non-migratory systems firmly anchor active components within packaging materials via chemical bonding or physical immobilization. This design enables active regulation of the packaging microenvironment without direct contact with food, thereby significantly extending the shelf life of food products and maintaining their quality. Given the importance of NMA-FP in food preservation, this paper focuses on analyzing the design principles of NMA-FP, including physically regulated, chemically responsive, and biologically immobilized types. It also summarizes and discusses the functional components commonly used in NMA-FP. Furthermore, special attention is paid to the technological innovation strategies for NMA-FP, such as covalent grafting technology, functional coating and interface engineering, nanocomposites and nanostructured materials, molecular sieve and adsorptive non-migratory systems, and passive stimulus-responsive systems. In addition, this paper summarizes relevant laws and regulations and provides an outlook on the future development trends of NMA-FP. Such packaging not only significantly extends the shelf life of food and maximally preserves its flavor, color and nutritional value, but more importantly, it addresses the potential migration safety risks of traditional active packaging at the source. Therefore, NMA-FP is not only an important technological breakthrough in the field of food packaging but also a key link in promoting the development of the food supply chain toward greater safety, intelligence, and environmental friendliness, representing the core development direction of future food packaging technology.</p>
