The object of the present invention is to provide a hot melt adhesive which is less likely to cause stringing and has excellent thermal stability, and further has excellent adhesion, in particular adhesion to a paper substrate. The present invention relates to a hot melt adhesive comprising: (A) a polar functional group-modified polymer, (B) a butyral resin, (C) an olefin-based polymer, and (D) a tackifier resin.

A hot melt adhesive composition contains a 1-butene homopolymer, an ethylene-based polymer having a melting point of lower than 80 C., an -olefin copolymer having a melting point 80 C. or higher, a tackifying resin, wax, and a liquid softener, in which the ethylene-based polymer includes at least one type of copolymer selected from the group consisting of an ethylene--olefin copolymer and an ethylene-vinyl acetate copolymer.

The present disclosure provides an article. The article includes a first substrate comprising a first propylene-based polymer and a second substrate comprising a second propylene-based polymer. The article includes an adhesive composition located between the first substrate and the second substrate. The adhesive composition includes (A) a block composite compatibilizer, (B) an ethylene-based polymer or a propylene-based polymer, (C) a tackifier, and (D) a wax. The adhesive composition bonds the first substrate to the second substrate with improved a lap shear strength.

Glue compositions and methods for their manufacture are provided. A glue composition contains a metallocene-catalyzed polyolefin wax present in an amount of at least 25 percent, by weight, and a tackifier present in an amount of at least 20 percent, by weight. The glue composition is solid at room temperature and is configured to provide an adhesive layer onto a substrate upon abrasion thereagainst.
