#$%^&*AU2018204439B220200227.pdf#####Abstract A hot melt adhesive composition containing a functionalized polymer, namely, a metallocene catalysed polyolefin elastomer grafted with maleic anhydride, together with a nonfunctionalized secondary polymer, namely, a metallocene catalysed random or black 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 labelling.
