Patent ID: 8481635

Claim:
A method making a disposable diaper having an elastic band, the method comprising forming an adhesive bond between an elastic band and an imperforate polymer film, the adhesive bond comprising: (a) an effective amount of a copolymer comprising ethylene and either hexene or octene having a degree of crystallinity at ambient temperatures of about 5 to 50% based on the copolymer, and density less than about 0.89 g-cm −3 ; (b) about 0.05 to about 35 wt % of a polyethylene polymer having randomly oriented substituents comprising an acid anhydride group, wherein the amount of acid anhydride is characterized by a saponification number of about 0.05 to about 15, the polyethylene polymer having a molecular weight M n of about 2000 to about 10,000; and (c) about 30 to 80 wt % of a hydrogenated tackifier, wherein the hot melt adhesive has a Brookfield viscosity at 150° C. of about 2000 to about 16000 cP and a creep of less than about 70%.
