摘要： In general, the present disclosure is directed to creped tissue webs, and products produced therefrom. The creped webs and products are strong, soft, and have improved strike-through and absorbency properties. The improvement in both strike-through and absorbency is achieved in-part by increasing the basis weight of the web, while at the same time reducing the creping composition add-on levels.
