Abstract: A method for making a laminate comprises the steps of applying a hot melt adhesive composition in a molten state to a primary substrate and mating a secondary substrate to the first substrate by contacting the secondary substrate with the adhesive composition. The composition comprises a polymer blend based on a low molecular weight semicrystalline propylene based polymer and a high molecular weight essentially amorphous propylene based polymer, both of which are prepared by using single-site catalysts. The composition further contains a compatible tackifier, a plasticizer, an antioxidant, and optionally a wax, a filler, a colorant, a UV absorber, another polymer, or combinations thereof. Particularly preferred applications include nonwoven disposable diaper and feminine sanitary napkin construction, diaper and adult incontinent brief elastic attachment, diaper and napkin core stabilization, diaper backsheet lamination, industrial filter material conversion, and surgical gown and surgical drape assemblies.
