Patent ID: 7445838

Claim:
A disposable diaper comprising a polyolefin film layer bonded to a synthetic non-woven layer using a low odor hot melt construction adhesive, the adhesive penetrating the fiber of the non-woven layer to embed the fiber in the adhesive, the construction adhesive comprising: (a) greater than about 40 wt % of a copolymer comprising an ethylene vinyl acetate copolymer having 27±5 wt. % vinyl acetate having a melt index greater than 800 gm-10 min −1 ; and (b) an effective amount less than 40 wt.-% of a tackifying resin with a softening point greater than about 100° C.; and (c) 0 wt % to 5 wt % of a wax, wherein the weight ratio of the copolymer to the tackifying resin is greater than about 1:1 and the construction adhesive provides an initial adhesion between the polyolefin film layer and the synthetic nonwoven layer of at least 90 g when applied by spiral spray to the polyolefin film layer at about 1 to 8 milligrams of adhesive per square inch.
