Designed for use with InvisiPac® Tank-Free™ Hot Melt System or other hot melt equipment, InvisiPac® Pattern Control System provides accurate material use data. Sudden change in material usage can alert operators to larger issue with system, saving waste and rework of improperly sealed boxes. Featuring color LCD interface, InvisiPac lets users convert from solid adhesive bead to stitched bead and provides on-screen pattern preview that eliminates guesswork in setting up bead locations.
