Nanocellulose (NC), including cellulose nanocrystals (CNCs), cellulose nanofibrils (CNFs), and bacterial cellulose (BC), has attracted a great deal of attention as a green packaging material. NC can protect food from pathogen adhesion and can be degraded by microorganisms after being discarded. In this review, we introduce preparations of NC-based film, including layer by layer (LbL) assembly, electrospinning, coating, extrusion, casting, vacuum filtration, and immersion. We summarize the interaction between microorganisms and NC, and focused on the impact of NC on microbial adhesion to surfaces and the influence of microorganisms on degradation of NC-based film. We put forward the challenges of NC faces in packaging, such as hydrophobicity, antibacterial properties, and industrialization. We finally propose future perspectives of NC-based film as the packaging material.
纳米纤维素（NC），包括纤维素纳米晶体（CNCs）、纤维素纳米纤维（CNFs）和细菌纤维素（BC），作为一种绿色包装材料引起了广泛关注。NC 可以防止食物受到病原体的附着，并且在丢弃后可以被微生物降解。在这篇综述中，我们介绍了基于 NC 的薄膜的制备方法，包括层层组装、静电纺丝、涂层、挤压、铸造、真空过滤和浸渍。我们总结了微生物与 NC 之间的相互作用，并重点讨论了 NC 对微生物表面附着的影响以及微生物对 NC 基膜降解的影响。我们提出了 NC 在包装方面面临的挑战，如疏水性、抗菌性能和工业化。最后，我们对 NC 基膜作为包装材料的未来前景提出了展望。
