6 Reasons to Choose InvisiPac

When it comes to hot melt systems for carton sealing applications, many companies share difficulties like these:

• High operating costs
• Productivity challenges
• Costly pop-opens and sealing issues
• Safety concerns from exposure to hot molten adhesive

Graco’s InvisiPac® Tank-Free™ Hot Melt System helps you tackle carton sealing challenges and achieve unmatched performance on your packaging lines.

Here are six reasons why many companies have already switched to InvisiPac.

InvisiPac’s high melting surface ratio and tank-free, melt-on-demand technology ensure a 10-minute start-up time. That’s up to nine times faster than tank-based systems, and twice as fast as tankless systems.

InvisiPac operates on a first-in, first-out (FIFO) principle that eliminates the risk of charring and thermal shock. This allows the viscosity of the adhesive to stay constant from the time it is melted to the point of dispense. See how FIFO works:

InvisiPac can help your packaging line use less adhesive, consume less energy, and need less maintenance. Most packaging lines use at least 30 percent less adhesive when they switch to InvisiPac. Some have experienced an 80 percent savings in adhesive usage.

InvisiPac’s heated and water wash hoses are made with a silicone-insulated layer. Its applicators contain a manifold filter in the heating zone that eliminates cold spots. Both help guarantee that boxes close without excess adhesive usage.

Tank-based and tankless hot melt systems are prone to charring, a leading cause of nozzle plugs, unnecessary hose replacement, and high maintenance costs. The InvisiPac Tank-Free Hot Melt System eliminates charring and requires only preventive maintenance. Its free-flow applicators have no dead spots where adhesive char can build up and clog nozzles.

Since InvisiPac is a fully closed system, operators are not exposed to hot adhesive and toxic fumes. Since char does not form in the automatic, tank-free hot melt system, operators do not need to scrape char buildup. This further prevents burn and slip hazards.
