Innovations in food packaging systems could meet the evolving needs of the market; emerging concepts of non-migrating technologies reduce the negative migration of preservatives from packaging materials, extend shelf life, and improve food quality and safety. Non-migratory packaging activates the surface of inert materials through pretreatment to generate different active groups. The preservative is covalently grafted with the resin of the pretreated packaging substrate through the graft polymerization of the monomer and the coupling reaction of the polymer chain. The covalent link not only provides the required surface properties of the material for a long time but also retains the inherent properties of the polymer. This technique is applied to the processing for durable, stable, and easily controllable packaging widely. This article reviews the principles of various techniques for packaging materials, surface graft modification, and performance characterization of materials after grafting modification. Potential applications in the food industry and future research trends are also discussed.
食品包装系统的创新可以满足市场的不断发展需求；新兴的非迁移技术概念减少了防腐剂从包装材料中的负迁移，延长了保质期，并提高了食品的质量和安全性。非迁移性包装通过预处理激活惰性材料的表面，生成不同的活性基团。通过单体的接枝聚合和聚合物链的偶联反应，将防腐剂与预处理包装基材的树脂共价接枝。共价键不仅为材料提供了所需的表面性能，而且保留了聚合物的固有特性。这项技术广泛应用于持久、稳定和易于控制的包装加工。本文综述了包装材料的各种技术原理、表面接枝改性以及接枝改性后材料的性能表征。还讨论了其在食品工业中的潜在应用和未来的研究趋势。
