Most hot melt glue systems are inefficient (and costly to maintain) because they process adhesive with a heated tank. This process creates temperature fluctuations and inconsistency with the adhesive - creating unnecessary downtime. Operator safety is compromised due to close proximity with molten adhesive.
Without a heated tank, InvisiPac Tank-Free hot melt glue systems utilize a melt-on-demand process - heating only the amount of hot melt adhesive material necessary. With this "first in, first out" approach, any charring and nozzle blocking is eliminated. Adhesive and maintenance costs are significantly reduced while improving productivity.
