Abstract

The gas barrier properties of packaging materials play a pivotal role in determining the fate of packaged food products. While multilayer composites provide precise control over gas transport, the growing demand for sustainability is stimulating research into barrier layers compatible with key polymer end-of-life pathways, including recyclability or composting. This review examines the technological advancements and design strategies for barrier coatings in food packaging, with a focus on wet coating technologies for polymers. The first section introduces the permeation theory and mass transport phenomena in multilayers. The second part delves into assessing various barrier coating systems, comparing key wet coating technologies reported in scientific literature, including organic-inorganic hybrid, nanocomposite, and multilayer coatings. The final section discusses significant findings and offers insights into the design of high-barrier wet coatings while considering their end-of-life implications and potential for industrial upscaling. This comprehensive review aims to highlight the critical role of innovative high-barrier coatings’ in overcoming the limitations of current multilayer composites, thereby fostering improved sustainability and preservation performance in food packaging applications.

通过湿沉积技术设计食品包装中可持续气体屏障涂层的策略

包装材料的气体阻隔性能对包装食品的命运起着举足轻重的作用。虽然多层复合材料提供了对气体输送的精确控制，但对可持续性的需求日益增长，这刺激了对与关键聚合物报废途径兼容的屏障层的研究，包括可回收性或堆肥性。本文综述了食品包装中屏障涂层的技术进步和设计策略，重点介绍了聚合物的湿涂层技术。第一部分介绍了多层介质的渗透理论和质量输运现象。第二部分深入评估各种屏障涂层系统，比较科学文献中报道的关键湿涂层技术，包括有机-无机杂化、纳米复合和多层涂层。最后一节讨论了重要的发现，并提供了对高屏障湿涂层设计的见解，同时考虑了它们的寿命终结影响和工业升级的潜力。这篇全面的综述旨在强调创新的高阻隔涂层在克服当前多层复合材料的局限性方面的关键作用，从而促进食品包装应用的可持续性和保存性能的提高。

期刊介绍： Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
