HST-01 Heat Seal Tester

HST-01 Heat Seal Tester is designed for laboratory use, to assess the heat seal ability of surfaces, sealant layers in films, laminates, polymers, and composites. Achieving effective seals involves three parameters: time, temperature, and pressure. HST-01 Heat Seal Tester recreates the sealing process by controlling these parameters.

To make a heat seal, the film must be melted together then allowed to cool down enough to become crystalline or solid. The three interdependent elements to heat-sealing are: Heat, Pressure and Dwell time, or we call sealing temperature, sealing pressure, and sealing time.

The optimum combinations of three factors will highly affect efficiency of sealing machine and heat seal strength.

So, a heat seal tester is used first before sealing machine settings, to find best three sealing parameters.
