Nanotechnology has shown many advantages in different fields. As the uses of nanotechnology have progressed, it has been found to be a promising technology for the food packaging industry in the global market. It has proven capabilities that are valuable in packaging foods, including improved barriers; mechanical, thermal, and biodegradable properties; and applications in active and intelligent food packaging. Examples of the latter are anti-microbial agents and nanosensors, respectively. However, the use of nanocomposites in food packaging might be challenging due to the reduced particle size of nanomaterials and the fact that the chemical and physical characteristics of such tiny materials may be quite different from those of their macro-scale counterparts. In order to discuss the potential risks of nanoparticles for consumers, in addition to the quantification of data, a thorough investigation of their characteristics is required. Migration studies must be conducted to determine the amounts of nanomaterials released into the food matrices. In this article, different applications of nanocomposites in food packaging, migration issues, analyzing techniques, and the main concerns about their usage are discussed briefly.
纳米技术在不同领域已展现出诸多优势。随着纳米技术应用的发展，它已成为全球市场食品包装行业一项颇具前景的技术。它已被证明在食品包装方面具有宝贵的能力，包括改善阻隔性能、机械性能、热性能和生物可降解性能，以及在活性和智能食品包装中的应用。后者的例子分别是抗菌剂和纳米传感器。然而，由于纳米材料的粒径减小，以及此类微小材料的化学和物理特性可能与其宏观对应物有很大不同，在食品包装中使用纳米复合材料可能具有挑战性。为了讨论纳米颗粒对消费者的潜在风险，除了对数据进行量化外，还需要对其特性进行全面调查。必须进行迁移研究以确定释放到食品基质中的纳米材料数量。本文简要讨论了纳米复合材料在食品包装中的不同应用、迁移问题、分析技术以及对其使用的主要担忧。
