Abstract of  CN105658754 (A)：

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 DEG C, and a wax. The composition may optionally include an aromatic reinforcing resin having a softening point equal to or higher than 115 DEG C, and a plasticizer. These hot melts provide superior hot tack, excellent adhesion, flexibility, and heat resistance above 150 DEG F in applications such as rigid packaging, hot fill packaging, and bottle labeling.
