The lab standard for flexible packaging. Features a massive 1000mm stroke for high-elongation films and pre-set 300mm/min speed for ChP 4008 Heat Seal testing. 0.5 Class Accuracy.
**Selection Guide:** Need to test films with high elongation (>500%)? Choose the XLW Series. Its extra-long stroke is designed for stretchy materials, whereas standard testers will run out of travel space.
The KHT XLW-PC is the globally preferred choice for flexible packaging laboratories. It boasts an **Extra-Long 1000mm Stroke**, making it the only viable option for testing high-elongation materials like PE films and laminates (ASTM D882).
**Intelligent Speed Control:** Compliance is built-in. The system features specific mode settings for **Heat Seal Strength (ASTM F88 / ChP 4008)**, automatically locking the test speed to **300mm/min** to prevent operator error and ensure inter-lab reproducibility.
