PARAM ^TM Heat Seal Tester seals the specimen to determine the seal parameters of basic film, laminated films, coating paper and other heat sealing laminated films according to the requirement of relative standards. The seal parameters include heat seal temperature, dwell time, and the pressure of heat seal. Heat seal materials that have different melting point, heat stability, fluidness, and thickness of could show various heat seal properties, which cause obviously different seal technique. Users can obtain standard heat seal index by HST-H3 Heat Seal Tester.
