The use of organic and inorganic materials to prepare membrane materials with functional performance has attracted much attention in recent years. In this paper, galactomannan (GM) is used as raw material and nano zinc oxide (nano-ZnO) is used as functional modifier to prepare GM based food packaging films. The properties influence for films of different nano-ZnO content were studied. The obtained nano-ZnO/GM composite films showed superior hydrophobicity and almost absorbing all UVA and UVB. The tensile strength of composite film was superior to plastic HDPE film, and the oxygen barrier properties of composite films were better than PVC plastic film. The composite films against E. coli and B. subtilis showed great antibacterial properties. The antibacterial effect was demonstrated by Shine-Muscat grapes after storage for 5 days. The final prepared GM based functional food packaging film provides a foundation for the potentials for futural plastic packaging alternatives.

近年来，使用有机和无机材料制备具有功能性能的膜材料引起了广泛的关注。本文以半乳甘露聚糖（GM）为原料，以纳米氧化锌（nano-ZnO）为功能改性剂，制备了基于GM的食品包装薄膜。研究了不同纳米ZnO含量对薄膜性能的影响。所获得的纳米ZnO / GM复合膜显示出优异的疏水性并且几乎吸收了所有UVA和UVB。复合膜的拉伸强度优于塑料HDPE膜，复合膜的阻氧性能优于PVC塑料膜。复合膜抗大肠杆菌和枯草芽孢杆菌表现出很大的抗菌性能。储存5天后，Shine-Muscat葡萄表现出了抗菌作用。最终准备的基于GM的功能性食品包装薄膜为未来的塑料包装替代品的潜力奠定了基础。
