HST-H2 Heat Sealer seals the specimen with press to test the seal parameters of laminated films, coating paper and other heat sealing laminated films. The seal parameters include heat seal temperature, dwell time, and the pressure of heat seal. Different melting point, heat stability, fluidness, and thickness of heat seal materials could make heat seal properties various, which cause obviously different seal technique. Users can obtain standard heat seal index by HST-H2 Heat Seal Tester.
