High green strength reactive hot melt adhesives are prepared using relatively low levels of reactive acrylic, and may be prepared with liquid crystalline or crystalline diols.

Reactive hot melt adhesive with improved hydrolysis resistance

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.

Hot Melt Adhesives

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 cigarette filter, process to manufacture, wherein a low application temperature ethylene copolymer based hot melt adhesive is applied to porous and/or nonporous plugwrap paper. As used herein, low application temperatures are temperature between 200&deg; F. and 300&deg; F. (93&deg; C. and 149&deg; C.), preferably, 240&deg; F. to 275&deg; F. (115&deg; C. to 135&deg; C.).

Low application temperature hot melt adhesive for cigarette preparation

The present invention is directed to hot melt pressure sensitive adhesive compositions, that exhibit excellent adhesion properties and improved thermal stability, said compositions comprising:

Hot melt pressure sensitive adhesives based on compatibilized blends of

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.
