Beschreibung
Zusammenfassung:	A method for applying a polymeric composition (130) discharged in a fluid form from a slot die applicator (102) to a substrate (106), the slot die applicator (102) including a slot opening (114), a first lip (116), and a second lip (118), the slot opening (114) located between the first lip (116) and the second lip (118); and the substrate (106) having a first surface (108) disposed opposite of a second surface (110) and an unconstrained caliper, Hs, the method comprising the steps of positioning the substrate carrier (104) adjacent the slot die applicator (102) to define a minimum distance, Hg, between the substrate carrier and the first lip (116) and the second lip (118) that is substantially the same or less than the unconstrained caliper, Hs, of the substrate (106). The polymeric composition has Tensile Strength at Yield of from about 0.5 MPa to about 10 MPa, as measured according to the Tensile Strength Test Method described herein. The method can be used to make absorbent articles having a substrate with an application pattern comprises continuous and/or discrete pattern elements having a dimension in machine direction of less than 10 mm.
