This is a convenient testing machine for heat seal tests of packaging plastic films and color development tests of thermal paper!
The thermal gradient testing machine is a device that can apply a predetermined temperature gradient (temperature difference) to five thermal plates and press them under the same conditions. When determining the optimal temperature for heat seal tests of packaging materials, heat resistance tests of woven fabrics, or color development tests of thermal paper, it is not necessary to raise or lower the temperature during the tests; the judgment can be made with simple operations.
