The invention discloses a preparation method of a water-resistant traditional Chinese medicine gelatin capsule. The preparation method comprises the following steps: S1, selecting a water-resistant material to prepare a water-resistant layer on the inner surface of the capsule; s2, preparing a double-layer capsule; s3, filling capsules and sealing; compared with an existing medical hollow capsule, a thin water-resisting layer is constructed on the inner surface of the capsule, and the capsule is sealed after being filled, so that the quality problem of the traditional Chinese medicine capsule due to moisture migration is fundamentally solved, the storage time of the traditional Chinese medicine capsule is effectively prolonged, the technological process is simple, and the cost is low. 本发明公开了一种阻水性中药明胶胶囊的制备方法，包括以下步骤：S1，选取隔水材料在胶囊内表面制备隔水层；S2，制备双层胶囊；S3，填充胶囊、封口；相比现有的医用空心胶囊，本发明通过在胶囊内表面构建一层很薄的隔水层，而且在胶囊填充后将其封口，从根本上解决中药胶囊剂由于水分迁移出现的质量问题，有效延长了中药胶囊剂的储存时间，且工艺过程简单，成本低廉。
