Abstract
In the practice of the invention, a multi-ply paper product or tissue having hardwood layers on the outside and on the inside provides reduced amounts of undesirable sloughing. The multi-ply product includes at least two plies, with three layers in each ply. Hardwood layers, such as for example eucalyptus-containing fiber layers, are provided on the outside surfaces of each ply and also on the interface of one or more plies. The resulting paper product may exhibit reduced sloughing, with little or no sacrifice in softness. A product having two, three, four, or more plies is shown.
