Abstract:
1. An adhesive comprising at least 80 wt % of a polyolefin base polymer, from 1 to 10 wt % of at least one functionalized polyolefin, and from 6 to 15 wt % of a wax, based on the total weight of the polyolefin base polymer, functionalized polyolefin and wax; wherein the wax has a weight average molecular weight at least 15% up to 150% of the weight average molecular weight of the polyolefin base polymer, a viscosity at 190° C. of 60 mPa·s or more, and a crystallization temperature greater than that of the polyolefin base polymer and at least 110° C.; and wherein the adhesive has the following properties: (a) at least 5% fiber tear at 2° C. using Inland paper board as a substrate; (b) at least 50% fiber tear at 25° C. using Inland paper board as a substrate; and (c) a set time of less than 3 seconds.
