Abstract
Paper products treated on two surfaces with a liquid resistant composition are disclosed. The paper products can be, for instance, bath tissues, facial tissues, paper towels, and industrial wipers. The liquid resistant compositions can include any additive that provides benefits to the product. For instance, the liquid resistant composition can be a softener containing a hydrophobic additive. In one embodiment, the hydrophobic additive is a polysiloxane. In accordance with the present invention, the water resistant composition is applied to each surface according to a pattern. Each of the patterns includes treated and untreated areas. The patterns are positioned on the paper product such that untreated areas on one surface are in correspondence with the treated areas on the other surface of the sheet.
