  • Patent number: 9822283
    Abstract: The present invention provides hot melt adhesives for disposable products. The hot melt adhesives may be applied at high-speed and at low temperature ranges. The hot melt adhesives also provide excellent adhesion to polyethylene and a nonwoven fabric. The hot melt adhesive comprises (A) a thermoplastic block copolymer, which is a copolymer of a vinyl-based aromatic hydrocarbon with a conjugated diene compound; and (B) a propylene homopolymer having a melting point of 100° C. or lower, which is obtainable by polymerizing propylene using a metallocene catalyst. The disposable products are produced at high-speeds and low temperature with the inventive hot melt, and therefore, the disposal products are produced efficiently and safely, and a nonwoven fabric and a polyethylene film of the disposable products are less likely to peel.
