Seal wires (how and why)

We supply seal wires for most heat seal packaging machines.

Our seal wires are of excellent quality and are mainly manufactured with an 80-20% Nickel-Chrome alloy. This is mainly dependent on the control unit used, we only supply seal wires with a low ohm resistance for electronically controlled seal equipment.

We can supply seal wires in any variety you need:

  • Most Seal wires are supplied clear, but they can also be given a PTFE coating.
  • Even deviating shapes, for example round or U-shape, are easily realised with the modern laser and water cutting machines.
  • The ends are often copper or silver plated for better water conduction.
  • Including end connectors

We have only a few types in stock due to the great variety in width and thickness, but our good collaboration with our factory means that we can offer you a full range of seal wires, whereby the delivery time is short and at competitive prices.

We do have PTFE coated seal and cutting wires in stock in ø 0,5 – 0,7 and 1mm

Seal wires are available in any version, with clear, copper plated or silver plated ends.
We can add end connectors to the ends, such as eyelets or lugs.
The seal wires can also be given a PTFE coating on one or both sides.

We have our products in stock, the PTFE coated seal cutting wire (colour green) is available in a diameter of 0.5mm – 0.7mm - 1mm and can arrange the new coating with PTFE of your seal knifes and seal sheets.

In order to determine which seal wire you currently use, we require the following information from you:

Shape:  The shape of the seal wire often determines the ohm resistance of the seal wire, they come in many varieties; please refer to the enclosed list.

Ohm resistance:  Besides the content of the material (alloy), the resistance of the seal wire is also determined by the width and thickness of the wire, the bigger the surface (width x thickness), the lower the ohm resistance.





Ohmse resistance






Ends:  The ends of the seal wires are often copper or silver plated, both materials have good heat conduction qualities, which limits the heat in the contacts, with additional benefit that the wires are less likely to break due to overheating, resulting in a longer life span and less production loss. 

Special copper plating:  We can also manipulate the heat emission of your seal wire with a special copper plating, or by adding additional copper plating at the bottom of your seal wire, we can remove a common problem that occurs during the “sealing of plastic bags and sealing with a side fold”.
