PTFE glass fabric films
We offer a wide range of different coating qualities for covers and supports used in film sealing or for general applications where sliding and/or non-stick properties are required.
- sections and sheets
- ready-made cover tapes for sealing bars (KB band)
- punched parts
PTFE glass fabric tapes are available in all dimensions, without adhesive in the centre, so that there is no adhesive creating a barrier for the impulse sealing element thus improving sealing seams.
Cover-strip . . . longer service life
Cover-strip . . . better sealing results
Cover-strip . . . less machine downtime
The impulse band can expand without damaging or creasing the glass fabric.
For special applications:
On high-speed machines, for instance, it is useful to insert the impulse bands into a PTFE tube.
This tube is formed and sealed from flat PTFE-fabric. The heat conductor is simply introduced into the tubular tape. Thermal insulation to the supporting bar is provided by the lower double layer (overlapping seal area).
Advantage: rapid cooling of the heating band.
