Abstract: A laminate comprises a primary substrate and a secondary substrate mated with the primary substrate through contact with a hot melt adhesive. The hot melt adhesive comprises a polymer blend based on a low molecular weight semicrystalline propylene based polymer and a high molecular weight essentially amorphous propylene based polymer, both of which are prepared by using single-site catalysts. The composition further contains a compatible tackifier, a plasticizer, an antioxidant, and optionally a wax, a filler, a colorant, a UV absorber, another polymer, or combinations thereof. Particularly preferred applications include nonwoven disposable diaper and feminine sanitary napkin construction, diaper and adult incontinent brief elastic attachment, diaper and napkin core stabilization, diaper backsheet lamination, industrial filter material conversion, and surgical gown and surgical drape assemblies.

Abstract: A hot melt adhesive composition comprises a polymer blend based on a first polymer component having a low melting point and is selected from a polypropylene homopolymer and a copolymer of propylene and ethylene and mixtures thereof; a second polymer component comprising an amorphous polyolefin; and about 30% to about 75% by weight of a tackifying resin. The composition optionally further contains a plasticizer, an antioxidant, a wax, a filler, a colorant, a UV absorber, another polymer, or combinations thereof. The hot melt composition has a viscosity equal to or less than about 80,000 cP at 180° C. and is useful for a variety of industrial applications including bonding together the substrates used in disposable hygiene products, such as nonwoven layers, elastic attachments, and thermoplastic films (polyolefin, polylactic acid, etc.). The hot melt adhesive composition may be dually functional, serving as an elastic component adhesive and a construction adhesive.

Abstract: A low temperature heat seal coating solution which contains an amorphous or semi-crystalline polyester or co-polyester resin, tackifier, anti-blocking agent, and solvent. The coating solution can be applied to a packaging web such as a foil or film by converters using conventional methods such as gravure, rod, slot die, or printing process. The heal seal coating can be sealed to itself or another substrate to manufacture food packaging bags or pharmaceutical blister packaging. The heat seal temperature can be as low as 70° C. under conventional equipment and conditions in the industry.

Abstract: A novel hot melt adhesive for bonding labels on plastic bottles is described. The adhesive comprises a blend of a styrenic block copolymer, an ethylene vinyl acetate copolymer, a tackifying resin, petrolatum and optionally a wax. The use of petrolatum instead of mineral oil provides for better elevated temperature resistance than traditional formulations.
