目的 综述国内外生物基施胶剂的最新研究进展，为高品质生物基施胶剂的工业化开发提供思路和理论依据。方法 在理解施胶机理的基础上，对现有生物基施胶剂(松香施胶剂、植物油基施胶剂和多糖施胶剂)的结构和性能“构效关系”进行归纳、总结和分析。结果 通过对生物基原料进行可控物理和化学改性，在不破坏纸张强度的基础上赋予纸张优良的防水、耐油、水蒸气阻隔等特性。结论 生物基施胶剂具有原料来源广泛、结构可调、无毒和可生物降解等突出优点，在未来纸包装材料中具有广阔的应用前景。

The work aims to review the latest research progress of bio-based sizing agents at home and abroad and provide ideas and theoretical basis for the industrial development of high quality bio-based sizing agents. Based on the understanding of the sizing mechanism, the "structure-function relationship" of existing bio-based sizing agents (rosin sizing agents, plant oil sizing agents and polysaccharide sizing agents) was summarized and analyzed. By controlling the physical and chemical modification of the bio-based raw materials, the functional bio-based sizing agents with excellent water resistance, oil resistance, together with water vapor barrier were obtained without destroying the strength of the paper. Bio-based sizing agent with advantages of wide raw material sources, adjustable structure, non-toxicity and biodegradability have broad application prospects in the future paper packaging materials.
