Different seal bar configurations available
The right seal solution protects products efficiently against external elements. KUNBA offers several seal systems for your specific application. This depends on the type of vacuum bag (PA/PE, shrink bag, bags with aluminium coating), thickness of the bag, the desired seal and other requirements. Learn how to choose the right seal for your vacuum packages.
Convex seal wires
Standard Double seal
KUNBA works with convex seal wires for its Double seal, Cut-off and 1-2 Cut-off seal. This ensures residue being pressed out from between the foils of the bag during the seal process and decreases the risk of leakage. Furthermore, convex seal wires empower a strong seal resistance thanks to the easy separation of the residue. Double seal is Henkelman's standard. It consists of two 3.5 mm convex seal wires.
Option: 1-2 Cut-off seal
Cut-off seal available for free
Cut-off seal consists of one 3.5 mm convex seal wire and one 1.1 mm round cutting wire to easily tear off the residual plastic.
The paid option of 1-2 Cut-off seal is similar. The only difference is that with 1-2 Cut-off seal the time and settings of the seal and cutting wire can be managed seperately. KUNBA developed 1-2 Cut-off seal for shrink bags in general and some vacuum bags made of resistant but thin foil. For the easy removal of the rest foil.
Available for free Wide seal
Certain types of vacuum bags have been pre-sealed on 3 sides. For a professional result, the seal on the remaining side equals the width of the other 3 pre-seals. The main advantage of Wide seal is the aesthetic, professional result.
8 mm Wide seal on table-tops and Marlin 52 10 mm Wide seal on floor and industrial models, except Marlin 52
Suitable for aluminium and thicker bags Bi-active seal
Bi-active seal is used when vacuum sealing aluminium or thicker bags. This seal system has seal bars on both the inside of the lid and on the front of the vacuum chambers, so the vacuum bag is being sealed from both sides of the bag. Bi-active seal is a paid option on KUNBA vacuum packaging machines.
Bi-active seal is available on Boxer 42XL, Toucan, Falcon and Polar series.
