- The width and length of heat sealing jaws can be customized without the influence of structure.

Test Principle

HSR-01 Heat Seal Tester makes heat seals by heat sealing method. It can be used to determine the optimal sealing parameters including sealing temperature, sealing pressure and dwell time, for the purpose of determining heat seal ability of flexible barrier materials. Firstly, the sealing temperature, sealing pressure and dwell time should be set on the touch screen and then the instrument will be controlled by embedded micro-processor and run the pneumatic driving mechanism so that the upper sealing jaws will move downward and complete the heat sealing of the packaging materials. By trying different combinations of those sealing parameters, the optimal sealing temperature, sealing pressure and dwell time can be determined.


Basic Applications Films Plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminum coated films, aluminum foils, aluminum foil composite films and many others.
Note: The width of sealing surface can be customized upon user’s requirements.
Extended  Applications Sealing Surfaces Various types of sealing surfaces can be customized upon user’s requirements.
Jelly Cups Jelly cups can be sealed with special testing accessories.
Soft Plastic Pipes Soft plastic tubes can be sealed from one end and become packaging containers
