  • Patent number: 5763516
    Abstract: Hot-melt adhesive compositions useful for packaging are disclosed. These hot-melt adhesive compositions are based on modified polyethylene and contain a linear, low density copolymer or terpolymer of ethylene and another alpha-olefin, a polyethylene graft copolymer, a tackifying resin, and a high-melting low viscosity wax. The hot-melt adhesive compositions disclosed herein produce very good adhesive bonds, even at high speed packaging conditions under a broad range of ambient packaging temperatures. These inventive adhesive compositions have a novel combination of good hot tack and good adhesive bond properties, even at extreme conditions.
