InvisiPac HM25c  Tank-Free Hot Melt Gluing System

Compact system for case and carton sealing

Où acheterDemander des informations

New design for compact solutions.

The InvisiPac HM25c tank-free hot melt dispensing system has a compact design making it easy to install in any packaging line. And because all the controls are included in the internal circuit board, the unit can work independent from its control panel (ADM). This means that the controls can be operated from afar or integrated into other control panels.

Keep track of your hot melt adhesive usage

Having a clear view on your production is key to acheive the best possible results. Therefore, Graco standardly offers a material tracking capability on every InvisiPac hot melt system. With material tracking you are able to:

  • Track material usage and other production events
  • Easily graph your hot melt glue consumption to track cost per unit, saving you money and ensuring quality
  • Receive alerts when material usage is out of desired range and performance notifications on your lines.

"In the first 90 days, we've had zero errors and have gone from using 30 pounds of adhesive each day to nine pounds."

Consistent hot melt temperature
  • Quick start-up – ready in less than 10 minutes
  • No tank, no char-plugged nozzles
  • Delivers consistent adhesive viscosity
  • No degraded material
  • A consistent, reliable seal
  • Little to no waste
  • Better dispensing control
  • Improved operator safety
  • Freedom to use any adhesive you choose
  • High performance with lasting components
