<p>A method and apparatus for packaging products between first and second plastic components (26, 36) sealed by using a hot melt adhesive applied by a dispensing applicator (40) in one of several serially arranged stations of a packaging operation. The first plastic component (26) is supported for indexing movement on a transport or is formed therein and moved under a hot melt applicator (40) which is continuously driven in a predetermined path of travel which inpart traverses the entire periphery of the product loaded first plastic component. The first plastic component (26) is stopped under the applicator (40) for a predetermined dwell time during which the applicator dispenses the hot melt adhesive, then advanced where the second plastic component (36) is applied to form a filled package which is then evacuated and sealed. Apparatus (98) is provided for preventing dripping or stringing of the hot melt adhesives.</p> |
