This instrument tests the hot tack strength of plastic film after heat sealed in different conditions of temperature, pressure and time.
Working Principle
Heat seal two layers of test sample, then pull and tear it off by a tear bar at the heat seal point; measure the force of tearing to evaluate the hot tack strength.
Standards
ASTM F1921, ASTM F2029, QB/T 2358, YBB 00122003
