Graco InvisiPac Tank-Free Melt-on-Demand Glue Systems for end of line Packaging 

Advanced Hot Melt Adhesive Technology for Modern Packaging

The Graco InvisiPac Tank-Free Melt-on-Demand Glue Application System represents the next generation of hot melt adhesive equipment, designed to improve efficiency, reduce maintenance, and eliminate the common issues associated with traditional tank-based glue systems.

At igluetech, we supply and support the full range of Graco

 InvisiPac systems, helping manufacturers across the UK optimise their packaging lines and adhesive application processes.


What is a Tank-Free Melt-on-Demand System?

Unlike conventional hot melt systems that continuously heat large volumes of adhesive in a tank, InvisiPac systems melt only the adhesive required—when it’s needed.

This innovative approach delivers significant operational advantages:

  • Eliminates adhesive charring and degradation
  • Reduces energy consumption
  • Improves glue consistency and bond strength
  • Minimises system maintenance and cleaningHow the Graco InvisiPac works

Key Benefits of Graco InvisiPac Systems

No Tank. No Char. No Compromise.

By removing the traditional glue tank, InvisiPac Tank-Free systems prevent burnt adhesive build-up, resulting in cleaner operation and longer-lasting components.

Proven Cost Savings & Efficiency Gains

The Graco InvisiPac HM25C is designed to significantly reduce both adhesive consumption and energy usage when compared to traditional hot melt tank systems.

Thanks to its on-demand melting technology, the system only heats and dispenses the exact amount of adhesive required. This eliminates unnecessary energy consumption and prevents adhesive degradation caused by prolonged heating of glue.

Up to 60% Reduction in Operating Costs

Customers using the InvisiPac HM25C have recorded savings of:

  • Up to 60% reduction in adhesive usage
  • Up to 60% lower energy consumption
  • Reduced waste from charred or overheated adhesive
  • Lower maintenance and spare parts usage

Why It Saves More Than Traditional Tank Systems

Conventional hot melt systems continuously heat large volumes of adhesive, which leads to:

  • Adhesive charring and waste
  • Higher energy bills
  • Increased maintenance requirements

In contrast, the HM25C’s tank-free design:

  • Melts adhesive only when needed
  • Maintains consistent adhesive quality
  • Reduces overall system running costs

This makes the InvisiPac HM25C an ideal solution for manufacturers looking to improve efficiency, lower production costs, and achieve a faster return on investment.

Consistent, High-Quality Adhesive Application

Ensure reliable bonding across all packaging formats with precise, on-demand adhesive delivery—perfect for high-speed packaging environments.

Improved Uptime

With fewer blockages, less cleaning, and reduced component wear, your production line stays running longer.

Compact & Easy Integration

Designed to integrate seamlessly into:

  • Carton erecting machines
  • Case sealers
