Abstract
Tissue products are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid. The additive composition may be incorporated into the tissue web by being combined with the fibers that are used to form the web. Alternatively, the additive composition may be topically applied to the web after the web has been formed. After the additive composition is applied to the web or otherwise incorporated into the tissue web, the tissue web is embossed. During embossing, the additive composition forms well defined embossments in the web that are water resistant. In one embodiment, the additive composition may also be used to bond multiple tissue webs together to form a multiple ply product during the embossing operation.
