With no tank char, no nozzle plugging, and warm up times of less than 10 minutes, the InvisiPac system is a trusted, proven alternative to traditional hot melt tanks in any packaging application, including both original equipment manufacturer (OEM) and end user installations in the food and beverage industry.
The InvisiPac Tank-Free™ Hot Melt Delivery System is designed based on a comprehensive system approach, which incorporates an integrated vacuum feed, state-of-the-art tank-free melter, superior heated hoses, an innovative applicator, and next-generation process control technology that provides easy, remote system analytics. At the heart of the innovative technology is the tank-free design, which reduces the amount of time adhesive spends at high temperatures, ultimately reducing char and degradation. Better adhesive quality leads to improved bead weight repeatability. Less char, combined with Graco’s no plug solution, means adhesive beads can be right-sized, resulting in less material waste and improved quality assurance.
With InvisiPac, operators have more choices – using less expensive adhesives when it makes sense, or selecting high-grade adhesives for applications requiring premium performance. In either case, the InvisiPac System provides adhesive throughput equivalent to, or better than, many traditional hot melt tank systems.
InvisiPac’s integrated vacuum feed system saves on labor costs by automatically pulling adhesive from a drum or bulk container based on the application’s real-time demand. Equipped with an ultrasonic sensor, the vacuum feed system continuously maintains optimum adhesive levels, keeps out paper dust and debris, and improves operator safety by minimizing burn hazards and operator strain. The advanced feed system operates perfectly no matter what the form – reliably feeding chicklets, pellets, pastilles, and more. Adhesive is both supplied and melted on-demand, only when needed, thus eliminating the traditional tank design than generates char and results in downtime.
An intuitive user interface tracks adhesive consumption – any operator can watch for trends and adjust accordingly to maintain the perfect amount of adhesive use for the application. The user interface also features graphics and text that make operations simple, with a single screen view of all heat zone temperatures. Straightforward troubleshooting makes it easy to get to the root of any operations issue, and the system provides USB-downloadable operating data, errors, and event history.
