Single or dual hot air guns, wired and integrated into machine functions, which apply precise amounts of hot air onto the just-applied tamper evident seal. Used when the band and closure are larger than the body of the package and there is no natural shoulder on which the band would rest (such as banding a tapered cup and lid). The heat guns shrink the band slightly, tacking it into position so it remains in place until reaching the shrink tunnel to complete the shrinking process. Benefit: produces consistently positioned tamper evident seals on difficult packages.
Make allowances for customer specified electrical voltage controls. Benefit: allows machine installation without providing different voltages, reducing costs.
(programmable logic controller) is standard on some models, optional on others. Benefit: PLC control enables certain additional control functions, data gathering and communications with a central line computer.
