Hot melt adhesive compositions containing hyper-branched SBS block copolymers and end use applications thereof. The hyper-branched SBS is characterized in having a ratio between light-scattering molecular weight (of non-di-block polymer) and GPC molecular weight (of non-di-block polymer) greater than 1.4 and having ratio between light scattering molecular weight molecular weight (of non-di-block polymer) and light scattering molecular weight molecular weight (of di-block polymer) greater than 5. The ratio between light scattering molecular weight MW (of non-di-block polymer) and light scattering molecular weight MW (of di-block polymer) also defines the number of arms for the hyper branched structure. The weight average molecular weight of each arm of the hyper-branched SBS block copolymer is less than about 100,000. These are multipurpose adhesives finding utility as packaging, labeling, construction and positioning adhesives, and are particularly well suited for use as elastic attachment adhesives in the manufacture of elastic-containing products, such as disposable absorbent elastic articles.

Hot melt adhesives containing styrene butadiene block copolymer

An autofeeding low application temperature hot melt application system comprises a hot melt tank, a compact integrated auto feed, and operates at temperatures of not more than 260&#xb0; F.

Integrated low application temperature hot melt adhesive processing system

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.

Hot melt adhesive

A hot melt adhesive comprising an adhesive polymer and a modified rosin-terpene, preferably a phenol modified rosin terpene. The adhesive is particularly useful in packaging applications.

Hot melt adhesive composition

Hot melt adhesives that contain an N-alpha olefin wax have substantially improved open times.

A low application temperature hot met adhesive composition and its use in carton, case or tray formation comprising from about 5 to about 60 weight percent ethylene vinyl acetate with about 30 to about 50 weight percent VA content and having a melt index of about 700 to about 4,000 dg/min; a tackifier; and wax with a melting point of about 125 to about 180&#xb0; F.

Low application temperature hot melt adhesive

A low application temperature, high heat resistant hot melt adhesive comprising an adhesive polymer and a modified rosin and/or modified terpene which has a molecular weight to softening point ratio of less that about 10. The adhesive is particularly well-suited for hot filled packaging applications.

A low application temperature hot met adhesive composition and its use in carton, case or tray formation comprising from ethylene vinyl acetate with greater than 30 weight percent VA and having a melt index of at least 700; a thermoplastic hydrocarbon resin derived from styrene, alpha-methylstyrene, and/or vinyltoluene, and polymers, copolymers and terpolymers thereof; a compatible adhesive promoting tackifier; and wax with a melting point of about 130 to 170 .degree. F.; and optionally comprising ethylene vinyl acetate with less than about 30 weight percent by weight of vinyl acetate and having a melt index of about 400 to 2500.
