InvisiPac
Start realizing major benefits with tank-free technology of the InvisiPac hot melt delivery systems. With a true melt on demand principle, the InvisiPac hot melt delivery systems eliminate adhesive char and improve productivity.
Reduce Spend and Increase Productivity with True Melt-On-Demand Technology
Graco’s InvisiPac tank-free hot melting system outperforms all existing tank and tankless systems on the market. With a true melt-on-demand design, the InvisiPac system delivers guaranteed savings and optimizes production. It makes your case and carton sealing operations more reliable, faster, safer, and more cost-effective.
The InvisiPac Difference
Profitable
With an industry-leading start-up time of just 10 minutes, InvisiPac tank-free technology results in a 48% reduction in start-up energy, helping you to achieve your sustainability goals. In addition, InvisiPac reduces adhesive usage by a minimum of 30% and potentially up to 70-80%. It also eliminates unplanned downtime caused by adhesive charring, nozzle plugging, and hose issues.
Reliable
The InvisiPac Hot Melt System keeps adhesive at a consistent temperature and viscosity. By avoiding temperature fluctuations and the formation of char, the material output remains constant during production hours with zero downtime. The InvisiPac applicator’s integrated module filtering eliminated plugged nozzles and a consistent bead of adhesive on every box. Track adhesive usage, system performance and line data from anywhere at any time to achieve your Industry 4.0 initiatives.
Safe
As operators have no direct contact with the hot molten adhesive, the InvisiPac system eliminates safety hazards such as burning, toxic fumes and slippage. When the adhesive inside the melter reaches a certain level, a signal is automatically sent to the feeding system, causing adhesive to be sucked from the container directly into the melter–all without operator intervention.
Better in Every Aspect
A Closer Look at the InvisiPac Hot Melt System
Automatic Feed System
Patented self-learning feed algorithm that takes the guess work out of filling your hot melt system
- The hopper automatically feeds the granules into the machine, based on your required output
- No burn risk as the operator does not come into contact with the heated areas and hot molten adhesive
- No debris or contaminants in the adhesive as the hopper is fully enclosed
Adhesive Melter
The innovative melting chambers efficiently heat the adhesive on demand
- Highest melting surface ratio which heats all the adhesive evenly
- True first-in first-out technology ensures the first adhesive in the melter is the first dispensed
- Adhesive char is eliminated due to the tank-free design ensuring material quality
- No thermal shocking: No hot adhesive comes into contact with cold adhesive
LineSite Remote Monitoring Solution
Track critical performance metrics anywhere, any time by adding the LineSite feature to the InvisiPac
- System data tracking and collection solution for smartphone tablet, or computer
- Save money by monitoring adhesive usage, temperature, production levels...
- Receive notifications and respond instantaneously to potential faults and diagnose them remotely
Advanced Display Module with Remote Monitoring Option
Provides accurate control of the complete system
- Pattern control available that allows you to save money by converting from a solid bead to a stitched bead with the push of a button
- Highly intuitive color LCD interface – easy to learn, easy to use
Heated Hose
Designed to reduce adhesive char buildup, resulting in more uptime and lower maintenance costs
- An additional silicone layer promotes even heating, eliminating hot and cold spots that cause char and skin formation
- Consistent viscosity of adhesive, from melter to applicator, no matter the hose length
- InvisiPac waterwash hoses for food-safe packaging operations are Rated to IPX6, an international standard for performance in waterwash applications
Plug-free Applicator
Eliminate downtime due to plugged nozzles
- Free-flow path designed to eliminate dead zones where char will build up, ensuring a consistent bead on every box
- No expensive pop-opens due to the manifold filter eliminating cold spots and ensuring consistent adhesive application
- Available for waterwash applications
