Tank-Free Hot Melt Adhesive Delivery System for the packaging industry

Graco’s InvisiPac uses an integrated vacuum system to feed adhesive pellets to an in-line melt chamber. A sensor monitors adhesive levels in this chamber and adds pellets as required, based on demand.

Because it’s engineered with a Tank-Free design, adhesive spends less time at high temperature, significantly reducing char, tank scraping and char-filled hoses.



  • Faster startup – ready in less than 10minutes
  • Tank-Free – adhesive supplied and melted to meet your applications demand.
  • Adhesive spends less time at high temperature – less char and material degradation.
  • Less char – reduced nozzle plugging, less system maintenance and more uptime.
  • Intuitive User interface – graphics and text make operation simple.
