Handheld Jaw Sealers: FDR vs. FKR vs. FIS

Choose among these handheld families by seam width, usable length and control placement—not by model number alone. FDR is listed at 15 mm with a separate controller; FKR at 10 mm with integrated temperature control; FIS at 5 mm with a separate control unit.

Start with the dimensions that rule models out

A specified 15 mm band makes FDR the first family to check, not proof the film will seal. For a 10 mm band, FKR has listed lengths from 200 to 600 mm. For a 5 mm band, the listed FIS lengths are 310, 410, 510 and 610 mm. For example, the FIS-300 designation does not mean a 300 mm published sealing length. Check the actual specification for the model you quote.

Consider where the controller will sit

Integrated control travels with the hand tool; a separate controller needs a place to sit and a cable path suited to the work. Compare these layouts with the operator’s reach and clearance, especially on a large or awkward pack. Confirm the configuration rather than assuming accessories or plugs from another model are interchangeable.

Use material trials to choose the finalist

Ask for a trial at the required bond width using the actual bag, not a generic sample. If the specification leaves a field blank, request written confirmation before purchase. Specify the job and target dimensions rather than asking for the largest or hottest available model.

  • • Required strip width and full seam length
  • • Inner sealing surface and any folded areas
  • • Control layout, destination voltage and plug
