  • Patent number: 5607754
    Abstract: A stack of paper web products such as tissues, towels, napkins, hankies, wet wipes, and the like, and a method for making same wherein a plurality of sheets of the paper web product are stacked one on top of the other with each of the folded sheets having a fold configuration that creates a substantially rectangular footprint having four edges. Each sheet in the stack has at least one folded edge. After formation of the stack, micro encapsulated chemicals such as essential oils are applied to the side of the stack such that the essential oil containing microcapsules become adhered to the individual sheets along the folds. This stack of sheets are then packaged thereby minimizing the amount of handling and manipulation of the stack and the individual sheets after the microcapsules have been applied thereto. The microcapsules on an individual sheet are caused to rupture by the extraction of individual sheets from the package and through normal use of the paper web product.
