At Henkelman you can choose from several sealing systems. The right system ensures that the desired final vacuum will effectively protect your product from external factors. Most machines are equipped with a double seal, and many have the free option to swap this for a cut-off seal. Machines prepared to work in an ESD safe environment that are suitable for packaging electronics are equipped with a bi-active seal. Whatever you need, you can choose from a wide range of different sealing technologies.
Convex sealing wires
The Double seal, Cut-off seal and the 1-2 Cut-off seal all use convex sealing wires. This ensures that any residue or moisture is pushed out of the folds in the bag during sealing instead of being pressed into them. This reduces the chance of leaks and makes the seal much stronger and more hygienic.

Bi-active seal
1-2 cut-off seal
Just like the standard cut-off seal, this seal consists of one rounded 3.5-millimetre sealing wire and one round 1.1-millimetre cutting wire. However, the difference is that you can adjust the settings for the sealing wire and cutting wire separately. This can be particularly useful when using shrink bags or bags made from strong but thin foil.
