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.
