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.

The InvisiPac Difference


Profitable

Profitable

With an industry-leading start-up time of just 10 minutes, Graco's InvisiPac tank-free technology results in a  reduction in start-up energy. In addition, InvisiPac reduces adhesive usage by at least 30% and eliminates unplanned downtime caused by charring, nozzle plugging and hose issues. All this contributes to guaranteed savings.

Reliable

Reliable

The InvisiPac Hot Melt System keeps adhesive at a consistent temperature and viscosity.  It operates on a First-In-First-Out (FIFO) principle that avoids 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

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.

InvisiPac Hot Melt System HM10 & HM25c Comparison
Venturi Feed Tube System Venturi Feed Tube System Venturi Feed Tube System

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 On-Board Hopper On-Board Hopper

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 User Interface User Interface

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 Automatic Feed System Automatic Feed System

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 Melter Melter

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 Advanced Display Module Advanced Display Module

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.
