1)通过狭缝涂布的方式将热熔温度为120℃的热熔型高分子材料涂布在原纸层1的上表面形成热熔密封层3，且所述狭缝涂布的温度为120℃，涂布量为15g/m2；
2)通过凹版印刷的方式，将高分子水性树脂涂布在热熔密封层3表面形成一水性密封层4，以密封热熔密封层3中可能产生的缝隙，并且，所述水性密封层4的干涂量控制在5g/m2，固化温度控制在120℃，其表面平滑度控制在400s，纸张水分含量＜5％；
3)采用凹版印刷的方式，在所述水性密封层4的表面凹版印刷形成水性印刷层5，其中，所述水性印刷层的固化温度为80℃；
4)通过凹版印刷的方式在所述水性印刷层5的表面形成一水性防护层6，以起到防止划伤所述水性印刷层5以及确保所述内衬纸的爽滑作用，其中，所述水性防护层6的干涂量5g/m2，固化温度控制在80℃，所采用的凹版凹坑深度为50μm；
5)通过喷涂的方式将粒径为1μm，比表面积为2000g/m2的高分子材料粉末喷涂于原纸层1的下表面形成保湿保香层2，其中，所述保湿保香层2的干涂量为1g/m2，且其固化温度为100℃；
7)加水对所述原纸层1的下表面进行还湿/加湿处理以在所述恒湿保质保香2的下表面形成水分还湿层7，以使得成品纸张的水分含量控制在5％±1％。
