Abstract
We have found a novel spray-on adhesive composition made from components including a high melt index polymer and a high melt tackifier that interact to produce a composition that can form a low odor, light color, non-tacky, hot melt adhesive material that can be used in disposable article manufacture. The adhesive is thermally stable at hot melt application conditions, is low in cost, is easily applied and produces high quality disposable articles.
Claims21
A disposable article comprising a film layer bonded to a non-woven layer using a hot melt construction adhesive, the construction adhesive comprising:
- (a) greater than about 40 wt % of a polymer comprising an ethylene α-olefin copolymer, an ethylene vinyl acetate copolymer or mixtures thereof having a melt index greater than 1000 gm-10 min−1;
- and
- (b) an effective amount of a hydrogenated hydrocarbon tackifying resin with a softening point greater than 120° C.;
- wherein the weight ratio of the polymer to the tackifying resin is greater than about 1:1.
