Abstract: Hot melt packaging adhesives comprising a base polymer component, a tackifier component and a wax component, which wax component comprises a soy wax, and are described.

Abstract: Low application temperature hot melt packaging adhesives comprising a vegetable derived wax such as a soy wax are described.

Abstract: A hot melt adhesive based on a functionalized metallocene polyethylene copolymer finds use in packaging applications where high heat resistance, as well as good cold tolerance, is required.

Abstract: Dye-labeled tackifiers increase dye solubility/compatibility and provide an improved means of introducing dyes into products such as inks, adhesives and coatings. When the dyes are radiation absorbing dyes, the dye-labeled tackifiers can serve as thermal transducers, and can be used in applications where it is required to cause a thermoplastic material to melt or to soften, for example a hot-melt composition.

Abstract: A hot melt adhesive based on ethylene-2-ethylhexyl acrylate copolymer finds use in packaging applications where high heat resistance, as well as good cold tolerance, is required.

Abstract: Low application temperature hot melt adhesives are advantageously used to releaseably bond an article, such as a plastic bottle to a base material, such as a cardboard palette.

Abstract: Hot melt adhesives comprising a polar tackifier are triacetin resistant and particularly advantageous for use as a plug wrap sealing adhesive. Particularly preferred for use in the practice of the invention are hot melt adhesives comprising a rosin ester tackifier.

Abstract: A hot melt adhesive comprising ethylene copolymers, a tackifier and wax is useful in bonding substrates made of polymer laminated paperboard. The adhesive is particularly useful in packaging applications.

Abstract: Curable compositions, reaction products of which are reworkable through thermal decomposition, are provided. Specific compounds useful in such curable compositions, as well as curable compositions and thermosets incorporating such compounds, are provided in the present invention. The compounds include a cyclic hydrocarbon moiety including an oxirane or thiirane group and an aromatic ether moiety including an oxirane or thiirane group. The cyclic hydrocarbon moiety and the aromatic ether moiety are joined to each other through an oxycarbonyl-containing linkage or a thiocarbonyl-containing linkage, preferably a secondary or tertiary linkage. Compositions incorporating such compounds are capable of curing by exposure to a specific temperature, and are decomposable at a temperature in excess of the curing temperature, thus providing a composition which is reworkable.

Abstract: A reactivatable adhesive that may be used on high speed case and carton sealing lines contains an energy absorbing ingredient that is capable of absorbing and reflecting radiant energy.
