Patent attributes
A hot melt adhesive composition, comprising a blend of components including about 1% to about 20% by weight of a styrene-ethylene-ethylene-propylene-styrene (SEEPS) random block copolymer; about 10% to about 70% by weight of a first midblock tackifying resin having a softening point of at least about 85° C.; about 0 to 65% of a second midblock tackifying resin; about 5% to about 60% by weight of a plasticizer; about 0% to about 20% by weight of an end block reinforcing resin having a softening point equal to or higher than 115° C.; and about 0.1% to about 5% of a stabilizer; wherein the components total 100% by weight of the composition, and the viscosity of the composition is equal to or less than about 20,000 mPa.s at 160° C. Laminates, especially those used in disposable soft goods, and methods of making such laminates using the hot melt adhesive composition are also described. The adhesive composition and/or laminate may be used in making a variety of end products such as a disposable diaper, a sanitary napkin, a bed pad, a bandage, a surgical drape, a tape, a label, a plastic sheet, a nonwoven sheet, a paper sheet, a cardboard, a book, a filter, or a package.
