How is InvisiPac's technology different?

Other hot melt systems use a tank or crock to keep adhesive heated for long periods
of time. That degrades material quality and produces more downtime and plug-forming char. The fluctuating temperature can also change material viscosity and cause inconsistencies in dispensing, forcing you to waste adhesive.

The InvisiPac system has a uniquely designed, melt-on-demand heating surface. The larger surface melts adhesive quickly and dispenses it immediately – when and how you need it.

Moreover, you can use almost any adhesive you choose; control your finances by making your own choices.

Use InvisiPac's Pattern Controller and you can save even more! And with LineSite, you can monitor your operation, even from a distance!
