Freestanding Sealers

IMPAK offers several sealers for bag sizes or applications which require a freestanding unit, as opposed to a tabletop sealer. These industrial-grade impulse heat sealers include horizontal and vertical sealers such as the Heavy Duty Impulse Sealer, or “heavy duty” units, the Gramatech CustomPak, the MasterWeld and the Pik N Pak. Compare models in the chart below or contact IMPAK to get advice based on your application.
