InvisiPac HM50

The Graco InvisiPac HM50 is a high-performance Tank-Free™ hot melt dispensing system capable of producing up to 22 kg of hot melt per hour. It is the ideal solution for high-volume final packaging applications that require speed, precision, and reliability.

Main features

  • High productivity: A melting capacity of 22 kg/h ensures a continuous flow of adhesive even on demanding packaging lines.
  • Quick startup: Reaches operating temperature in just 10 minutes — the fastest startup time on the market.
  • Tank-Free™ technology: The tankless system prevents the adhesive from carbonizing and avoids thermal shock, thereby extending the device's service life.
  • The FIFO principle: The adhesive that is loaded first is melted and dispensed first, ensuring the quality of the material.
  • Flexible number of outputs: Configurable for two to six output channels, depending on the line's requirements.
  • Automatic vacuum feeding: Reduces manual labor and ensures a continuous supply of adhesive.
  • Integrated pattern control: Allows you to preset various adhesive patterns for precise and repeatable processing.

Typical applications

The InvisiPac HM50 is particularly well-suited for high-volume packaging lines that require reliable and automated hot-melt adhesive dispensing: sealing cardboard boxes, sealing bags, gluing together tray boxes, and joining multi-layer packages.

Frequently asked questions

What is the advantage of Tank-Free™ technology over a conventional tank-based system?

In the Tank-Free™ system, the adhesive melts in small quantities as needed, which drastically reduces the adhesive’s exposure time to high temperatures. This results in less carbon buildup, a cleaner product, and shorter maintenance downtime.

How many output channels does the InvisiPac HM50 have?

The system can be configured with 2–6 output channels, depending on the packaging line's requirements.

What types of adhesive materials are suitable?

InvisiPac HM50 is compatible with EVA-, PO-, and PSA-based hot melts supplied in granule or block form.

The Tank-Free™ system provides a hot-melt adhesive for gluing packaging on demand.

  • - The in-line thawing machine is capable of producing 22 kg per hour and reaches operating temperature in 10 minutes - the fastest start-up time of any packaging line.
  • - "Melt-on-Demand" technology ensures a continuous adhesive flow. Less time at high temperatures means more uptime and less downtime for maintenance.
  • - FIFO (First-in, first-out) ensures that the first glue is melted and dispensed first, eliminating glue char and thermal shock.
  • - The integrated automatic vacuum feeding system saves labour costs by automatically drawing glue from the drum or bulk hopper.
  • - The lack of exposure to molten hot melt improves operator safety by reducing the risk of burns.
  • - The pattern control feature switches the dispensing from a solid bead to a stitched bead at the touch of a button, saving time and money.
  • - An optional indicator light provides a visual indication of the system status.
  • - An intuitive user interface monitors glue consumption and simplifies troubleshooting with USB downloadable usage data, error and event history.
