摘要： Stretch laminate hot melt adhesives and stretch laminates are described. The stretch laminate hot melt adhesives are suitable for adhering elastic materials with inelastic substrates, and allow permanent deformation of the inelastic substrate and extensions and retractions of the elastic materials. The stretch laminate hot melt adhesive is particularly suitable for back ear lamination for disposable absorbent articles.

摘要： Adhesives, methods to bond substrates together with the adhesives, and articles of manufacture comprising the adhesives are described. It has been discovered that an adhesive with a polymer content greater than 70 weight percent can be formulated with a blend of (i) a metallocene catalyzed polypropylene polymer that has a density range of about 0.70 to about 0.91 g/cm3 and a melt viscosity less than 50,000 cP at 190° C. and (ii) a Ziegler-Natta catalyzed amorphous polybutene and/or polypropylene copolymer. Such adhesives have high creep resistance making them particularly well suited for disposable personal care garments.
