Abstract
The present invention relates to a method of applying a hot melt adhesive to an absorbent article, such that the article has low autoadhesion, yet maintains excellent attachment properties during use in a consumer's undergarments. This is achieved by selecting the rheological properties of the adhesive and the mechanical properties of the substrate being coated. The adhesive is directly applied to a backsheet layer outer surface, wherein the adhesive has a viscosity of less than about 10,000 centipoise at a temperature of about 130 to about 177 degrees Celsius. The backsheet layer has a tensile strength of at least 5 Newtons per 25 millimeter width of material.
