Abstract:
A hot melt adhesive comprises an ethylene α-olefin copolymer, an acid anhydride modified polyolefin and a hydrogenated tackifying resin. The hot melt adhesive has excellent viscoelastic properties and can be used in a variety of applications. In one application, attaching an elastic band to a flexible film, the adhesive has excellent viscosity and, in a finished absorbent article, a minimal creep characteristic. Also disclosed is a disposable article using the adhesive to adhere adjacent surfaces within the disposable article including an elastic band to a polyolefin backing film, for example, in a diaper, incontinent article or other such structure.
