ABSTRACT A method and apparatus are providing for packaging products between first and second plastic components sealed by using a hot melt adhesive applied by a dispensing applicator in one of several serially arranged stations of a packaging opera- tion. The first plastic component is supported for indexing movement on a transport or is formed therein and moved under a hot melt applicator which is continuously driven in a pre- determined path of travel which in part traverses the entire periphery of the product loaded first plastic component. The first plastic component is stopped under the applicator for a predetermined dwell time during which the applicator dis- penses the hot melt adhesive, then advanced where the second plastic component is applied to form a filled package which is then evacuated and sealed. Apparatus is provided for preventing dripping or stringing of the hot melt adhesives.
