ABSTRACT:
The hot-melt adhesives of the present invention comprise a blend of ethylene-vinyl acetate copolymer, hydrocarbon tackifier resin, aromatic low softening point tackifying resin and paraffin wax. These hot-melt adhesive compositions provide adhesives especially useful for bonding polyethylene film to a nonwoven support. The bonds provided by this adhesive have a novel combination of properties such as good static shear lap bond strength, low elongation and good elevated temperature properties.
