Questions on this line
What is the difference between FS and F tapes? +
FS tapes are 100% skived PTFE film — thinner, more conformable, for delicate sealing bars. F tapes use a fiberglass base for higher tensile strength.
Maximum width? +
FS-series tapes are supplied within a maximum width of 600mm.
Temperature range? +
-70~260°C continuous working range.
Selection & Troubleshooting Guides
Heat sealing tape: five failure modes and the grade that fixes each
When a packaging line starts producing bad seals, the tape is usually the first part replaced and the last part diagnosed. These are the five failure modes we see most, and the grade-level fix for each.
PTFE vs silicone coated fiberglass: how to choose
Both coatings sit on the same fiberglass platform and both survive temperatures that destroy ordinary fabrics. They are not interchangeable. The choice comes down to four measurable differences.
