The research in eco-friendly and sustainable materials for packaging applications with enhanced barrier, thermo-mechanical, rheological and anti-bacterial properties has accelerated in the last decade. Last decade has witnessed immense interest in employing nanocellulose (NC) as a sustainable and biodegradable alternative to the current synthetic packaging barrier films. This review article gathers the research information on NC as a choice for food packaging material. It reviews on the employment of NC and its various forms including its chemico-physical treatments into bio/polymers and its impact on the performance of nanocomposites for food packaging application. The review reveals the fact that the research trends towards NC based materials are quite promising for Active Packaging (AP) applications, including the Controlled Release Packaging (CRP) and Responsive Packaging (RP). Finally, it summarizes with the challenges of sustainable packaging, gray areas that need an improvement/focus in order to commercially exploit this wonderful material for packaging application.
在过去的十年中，人们加快了对环保和可持续包装材料的研究，这些材料具有增强的阻隔、热机械、流变和抗菌性能。过去十年中，人们对纳米纤维素（NC）作为当前合成包装阻隔膜的可持续和可生物降解替代品产生了浓厚的兴趣。本文综述了 NC 作为食品包装材料的选择。它回顾了 NC 及其各种形式的应用，包括其化学物理处理到生物/聚合物中，以及对用于食品包装应用的纳米复合材料性能的影响。综述表明，基于 NC 的材料的研究趋势对于活性包装（AP）应用非常有前景，包括控制释放包装（CRP）和响应性包装（RP）。最后，它总结了可持续包装的挑战，以及为了将这种优秀的材料商业化应用于包装，需要改进/关注的灰色地带。
