InvisiPac
Eliminate adhesive char and advance productivity with InvisiPac melt-on-demand adhesive dispense for case and carton sealing. Tank-Free™ hot melt delivery outperforms tank and tankless melters at any speed, making end-of-line packaging more cost-effective, faster, and safer.
Discover the InvisiPac Difference
Profitable With a 10-minute start-up time, InvisiPac speeds up profitability while conserving energy and reducing waste. True melt-on-demand technology lowers adhesive usage by at least 30 percent and ends unplanned downtime due to adhesive charring, nozzle plugging, and hose issues.
Reliable InvisiPac operates on a first-in first-out (FIFO) principle that eliminates charring and thermal shock. Hot melt adhesive stays at the required temperature and viscosity as it moves to the point of dispense. InvisiPac Plug-Free™ applicators dispense a consistent bead of adhesive hot melt on every box, preventing pop-opens.
Safe Since they have no direct contact with hot molten adhesive, InvisiPac operators are safe from burns, toxic fumes, and other hazards.
Tank-Free Hot Melt Technology
InvisiPac HM10 and HM25c can improve end-of-line packaging productivity at any speed, within the same compact footprint.
Venturi Feed Tube System
Automatic feed supplies only the amount of hot melt adhesive pellets needed.
Venturi feed hose connects directly to the melter inlet.
Operators use air control to adjust pellet speed. Remote feed option also is available.
On-Board Hopper
A low profile and clear lid make it easy to quickly fill and monitor the hot melt system. An external shaker underneath the hopper helps prevent clumping as the pellets move to the Venturi feed inlet.
Operator accessed components are not heated, effectively preventing burn injuries.
User Interface
Intuitive, nine-inch touchscreen allows for better process control and operation. The display is tilted, so that it’s easy to see and manage the following:
- Hot melt target and real temperature
- System setup and diagnostics
- Maintenance reminders and advice
- Material consumption logs
Automatic Feed System
Patented self-learning feed algorithm takes the guesswork out of filling the hot melt system. The hopper automatically feeds the granules into the machine, based on 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
Melter
Chambers with high melting surface ratio evenly heat hot melt adhesive pellets. First-in-first-out system ensures the first adhesive melted is the first dispensed, eliminating adhesive char and thermal shocking.
Advanced Display Module
The intuitive color LCD interface is easy to learn, making it easy to accurately control the complete hot melt system.
Pattern control option converts dispense from a solid bead to a stitched bead with the push of a button, saving time and money.
