Graco Inc. recently announced its new InvisiPac™ Tank-Free™ hot-melt delivery system for case and carton sealing applications is available through distributors. InvisiPac’s innovative tank-free design can significantly reduce the char created by traditional hot-melt systems because the adhesives spend less time at high temperatures. In addition, startup times on an InvisiPac production line will be approximately 10 minutes or fewer, compared to 35 minute startups for traditional hot-melt systems that use a tank to heat the adhesives.

“InvisiPac was engineered to solve the complex and costly problems associated with traditional hot-melt systems that rely on a tank to bring adhesives up to a temperature of 350°F or more,” said Nick Long, Product Marketing manager. “Without a tank attached to the system, InvisiPac reduces char and nozzle plugging, eliminates the need for constant tank scraping, and ultimately lowers the end user’s maintenance requirements.”
