目的 为制备性能良好和绿色环保的聚乙烯醇薄膜提供一定的理论依据。方法 分类介绍壳聚糖、纳米纤维素、可降解塑料、蛋白质等生物质材料增强聚乙烯醇薄膜及其在食品包装领域的研究现状。 结果 虽然通过与不同的生物质材料共混改性，可获得性能较为优良的聚乙烯醇薄膜，且用作食品包装时，具有抗菌与抗氧化、智能标签和整体保鲜的效果，但成本问题制约了实际生产。结论 利用生物质材料可以增强聚乙烯醇薄膜的综合性能，在食品包装领域有较好的发展前景。

The work aims to provide a certain theoretical basis for preparation of polyvinyl alcohol films with good performance and environmental protection. The biomaterials reinforced polyvinyl alcohol film including chitosan, nanocellulose, degradable plastics, protein and its research status in food packaging were introduced as per classification.Although polyvinyl alcohol film with better performance can be obtained through modification by blending with different biomass materials, and it had the effects of antibacterial and anti-oxidation, smart labels and overall preservation when used as food packaging. Cost issues restricted the actual production. Biomass materials can enhance the comprehensive properties of polyvinyl alcohol films. It a good prospect in food packaging.
