How do I heat-seal correctly?

We want to help you to have fun with your heat-seal machine for as long as possible and to heat-seal labels and transfers correctly.

Therefore, proceed as follows:

The preparation

  1. Check the heating plate for contamination and damage (and replace if necessary). Remove impurities on the Teflon with cleaning paste.
  2. Check the silicone pad for damage and consistency. If the pad is too soft, it must be replaced
  3. Switch on heat-seal machine
  4. Check the temperature with the temperature measuring strips

Here you will find our accessories for heat-seal machines:



Label Position

  • Find a flat area without seam on the textile
  • Choose a position that is comfortable for the wearer


  • First test the textile for temperature sensitivity
  • Materials that cannot be heat-sealed: pure new wool, polychlorinated fibre, chlorinated fibres and materials containing PVC
  • Coarse meshed fabrics, e.g. knitwear: look for a dense area on the fabric, where the label can attach to the fabric best
  • Stretchy fabrics, e.g. underwear or socks:
    • Use an elastic label (CT2009)
    • Heat-seal lengthwise
    • Do not stretch over the lower plate

Good to know:

Every textile presents its own challenges. The heatsealing process must be adjusted perfectly to achieve a lasting label on the chosen textile, despite the challenges. The following parameters must be set correctly for this:

  • Pressure
  • Temperature
  • Time
