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.
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:

By removing the traditional glue tank, InvisiPac Tank-Free systems prevent burnt adhesive build-up, resulting in cleaner operation and longer-lasting components.
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.
Customers using the InvisiPac HM25C have recorded savings of:
Conventional hot melt systems continuously heat large volumes of adhesive, which leads to:
In contrast, the HM25C’s tank-free design:
This makes the InvisiPac HM25C an ideal solution for manufacturers looking to improve efficiency, lower production costs, and achieve a faster return on investment.
Ensure reliable bonding across all packaging formats with precise, on-demand adhesive delivery—perfect for high-speed packaging environments.
With fewer blockages, less cleaning, and reduced component wear, your production line stays running longer.
Designed to integrate seamlessly into:
