How is InvisiPac's technology different?

Tank-based systems keep your glue heated for long periods of time. This degrades material quality and produces time-consuming, plug-forming char. The fluctuating temperature changes your glue viscosity, causing inconsistencies in dispensing and uncontrolled glue waste

With InvisiPac, you’ll experience far less downtime and produce more with a better seal. You’ll use far less adhesive and be able to drastically reduce your spare parts inventory. All delivering more profits to your bottom line. And have the data to prove it!

How? The difference is the technology. No tank. Period. 

The innovative design, with larger melting surface, melts your glue fast, and dispenses it immediately, controlling a consistent viscosity and dispensing exactly what is needed, down to the hundredth of a gram.

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

-- Plant Manager, Worldwide Meat Producer


Recovering those wasted grams is standard with InvisiPac systems and can add up to BIG SAVINGS.
