Abstract:
A hot melt adhesive composition containing a functionalized polymer, namely, a metallocene catalyzed polyolefin elastomer grafted with maleic anhydride, together with a non-functionalized secondary polymer, namely, a metallocene catalyzed random or block polyolefin elastomer having a melt index equal to or greater than 15, a first tackifying resin having a softening point of at least 95° C., and a wax. The composition may optionally include an aromatic reinforcing resin having a softening point equal to or higher than 115° C., and a plasticizer. These hot melts provide superior hot tack, excellent adhesion, flexibility, and heat resistance above 150° F. in applications such as rigid packaging, hot fill packaging, and bottle labeling.

Claim (Index 1):
A hot melt adhesive composition, comprising:\n about 5% to about 50% by weight of a functionalized polymer comprising a metallocene catalyzed random polyolefin elastomer grafted with maleic anhydride; about 5% to about 70% by weight of a non-functionalized polymer comprising a metallocene catalyzed random or block polyolefin elastomer as a secondary polymer with melt index equal or greater than 15 MI; a solid or liquid plasticizer in an amount up about 30%; about 5% to about 30% by weight of a wax; about 20% to about 70% by weight of a first tackifying resin having a softening point of at least about 95\u00b0 C.; about 0% to about 20% by weight of an aromatic reinforcing resin having a softening point equal to or higher than 115\u00b0 C.; about 0.1% to about 5% by weight of a stabilizer; and about 0% to about 3% by weight of auxiliary additives; wherein the viscosity of the composition is equal to or less than about 20,000 centipoise at 163\u00b0 C. and the composition has an initial average peel force equal to or greater than 200 grams at room temperature using hard to bond clear label films selected from the group consisting of clear polypropylene, polyethylene, polypropylene/polyethylene, and metalized oriented polypropylene label films.
