    摘要: The hot-melt adhesives of the present invention comprise a blend of polyethylene, tackifier resin, and ethylene-alkyl acrylate or alkenyl carboxylate copolymers. These adhesive compositions have low melt viscosities, good flexibility at 20.degree. F., and provide good page pull and page flex values on books bound with these adhesives. Therefore, these adhesive compositions are useful as hot-melt adhesives for use in bookbinding applications.

    摘要: The hot-melt adhesives of the present invention comprise a blend of poly(propylene-co-higher 1-olefin), tackifying resin and crystalline propylene containing polymer. These hot-melt adhesive compositions have a novel combination of properties including strong T-peel and lap shear bonds to both low- and high-density polyethylene with excellent creep resistance at ambient temperatures. Therefore, these new hot-melt adhesives are excellent adhesives for applications such as sealing high-density polyethylene grocery bags and low-density shipping bags.
