HOT MELT ADHESIVES COMPOSITIONS
Hot meld adhesive compositions : One or more ethylene based copolymers, no greater than about 27 % by weight of a tackifying agent and a wax.
Hot melt adhesive compositions are solid at room temperature and melt at higher temperatures. Hot melt adhesives compositions can be used in packaging applications e.g. to close box tops and also to form cases, cartons and / or trays.
Hot melt adhesives used in packaging should exhibit good bond formation across a broad temperature range, heat resistance, and a fast set time to be commercially useful.
Hot melt adhesive compositions for packaging are made from a variety of different base polymers including ethylene based copolymers ( e.g. ethylene vinyl acetate).
Hot melt adhesive compositions for packaging can include tackifying agent and wax as well. The tackifying agent used with ethylene vinyl acetate type polymers is often a polar tackifying agent such as e.g. rosin or functionalized terpene based resin. In some applications, it can be desirable to use a hydrogenated hydrocarbon based tackifying agent to lower the color of the hot melt adhesive.
At times, it would further be useful to be able to limit the tackifying agent in the hot melt adhesive composition.
