InvisiPac. So reliable, you'll forget it's even there.

Keep your packaging line up and running with the Graco InvisiPac. Say good-bye to daily maintenance due to char. No more char-filled hoses. No more tank scraping. No more wasted time waiting for your hot melt tank to heat up. With the Graco InvisiPac, you’re up to operating temperature and running production in less than 10 minutes.

Because it’s engineered with a Tank-Free design, adhesive spends less time at high temperature, significantly reducing char and its negative side effects. You get great performance – even from low cost adhesives.
