HSR-05 Gradient Heat Seal Tester can be used to determine the heat sealing parameters including dwell time, sealing pressure and sealing temperature for plastic films, flexible composite films, plastic coated paper and other heat-sealable films. The melting point, thermal stability, fluidity and thickness are the factors that may influence the heat sealing properties of materials. The heat sealing parameters for those materials are quite different.
Technical Features
