The invention relates to a low application temperature hot melt adhesive. More specifically, the low application temperature hot melt adhesive comprises olefin copolymers with an average Melt Index greater than 5 but less than about 35 g/10 minutes at 190 C. The adhesive is particularly useful in the construction of nonwoven articles.

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.
