目的 研究无铝内衬纸使用不同类型油墨及涂布层数的组合，得到阻隔性能优良的样品，推动无铝内衬纸的生产应用。方法 采用扫描电子显微镜、水蒸气透过率测试仪、透气性测试仪测试内衬纸的表面微观结构、透湿率和透气性，考察对比不同来源内衬原纸、单层多层涂布无铝内衬纸的阻隔性能，并与其他类型内衬纸性能做比对分析。结果 无铝内衬纸在原纸基础上涂布多层油墨，可显著提升产品的阻隔性能。单层涂布透湿率最大降低了59.80%，透气性最大降低了98.37%;三层涂布后透湿率趋于稳定，降幅为79.70%，而随涂布层数的增加，阻气效果提升不明显。结论 纸张涂布多层油墨能获得阻隔性能优良的无铝内衬纸，其阻隔性能与常规直镀内衬纸相近。

The work aims to study the combination of different types of inks and coating layers used in aluminum free lining paper, to obtain samples with excellent barrier properties and promote the production and application of aluminum free lining paper. The surface microstructure, water vapor permeability and air permeability of lining paper were tested by scanning electron microscope, water vapor permeability tester and air permeability tester. The barrier properties of lining base paper from different sources and single-layer coated and multi-layer coated aluminum free lining paper were investigated and compared with those of other types of lining paper. Coating multi-layer ink on the basis of base paper could significantly improve the barrier properties of the product. The maximum water vapor permeability of single-layer coated sample was reduced by 59.80%, and the maximum permeability was reduced by 98.37%. After three-layer coating was adopted, the water vapor permeability tended to be stable, with a decrease of 79.70%. With the increase of the number of coating layers, the effect improvement of air resistance was not obvious. Aluminium free lining paper with excellent barrier properties can be obtained by coating multi-layer ink on paper, and its barrier properties are similar to those of conventional direct plating lining paper.
