RDM Test Equipment

HT1XS Hot Tack Tester

Touch Screen Precision Hot Tack Tester for determination of the hot tack seal strength of flexible packaging materials, to ASTM F1921.

In vertical (VFFS) and horizontal (HFFS) form-fill operations, heat seals are often subjected to forces whilst still hot. If the hot seals are unable to resist these forces then unsealed areas or holes into the package can occur during the process. The RDM HT-1XS Hot Tack Tester measures the strength of hot seals enabling selection and compliance testing of suitable flexible materials for packaging applications. Precise control of sealing process variables (temperature, pressure, and time) in production then enables an optimal balance between material specification, packaging machine speed and seal integrity.
