Claim:
1. An adhesive-coated substrate comprising: a substrate having a predetermined surface area; and a hot melt adhesive disposed upon said substrate, wherein said hot melt adhesive comprises a multi-slot pattern comprising a plurality of first, horizontally spaced, upstanding high-crest portions, wherein each one of said plurality of first, horizontally spaced upstanding high-crest portions has a substantially first predetermined height dimension such that said plurality of first, horizontally spaced, upstanding high-crest portions of said hot melt adhesive cumulatively define a predetermined volumetric amount and surface area of said hot melt adhesive so as to provide sufficient adhesive bonding as necessary, and a plurality of second, horizontally spaced low-trough portions interposed between said plurality of first high-crest portions, wherein each one of said plurality of second, horizontally spaced low-trough portions of said hot melt adhesive has a second predetermined height dimension which is less than said first predetermined height dimension of each one of said plurality of first, horizontally spaced, upstanding high-crest portions, so as to effectively define a relatively reduced overall surface area of said hot melt adhesive relative to said predetermined surface area of said substrate, so as to thereby effectively eliminate or significantly reduce adhesive blocking, wherein said first predetermined height dimension of each one of said plurality of horizontally spaced first high-crest upstanding portions of said hot melt adhesive is approximately 4 mils, while said second predetermined height dimension of each one of said plurality of horizontally spaced second low-trough portions of said hot melt adhesive is approximately 2 mils.
