HT-1XS 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.

Description

Accuracy and repeatability in laboratory heat seal testing is vital, and the HT-1XS Hot tack tester provides the technology and reliability to deliver time after time. The HT-1XS seals and then immediately measures the peel strength of the hot seal. An intelligent controller and touch screen user interface provide test setting options, and allows multiple settings to be stored for later recall. Resulting graphs and data of load v time and load v temperature can be viewed, printed and exported to spreadsheets / SPC systems.

Testing is performed in accordance with ASTM F1921. The RDM HT-1XS Hot Tack Tester is used by leading film producers and converters across the world, and is backed by our direct support offices and by our trained service partners worldwide.

HT-1XS Hot Tack Tester meets the following standard: ASTM F1921.

For industrial PC model see the HT-1PC.

Features & Benefits

Features:

Five sealing jaws with individual temperature control and settings: Up to five sealings with different temperature settings can be run simultaneously in one operation.
Broad temperature range: For each of the five sealing jaws, you can preset a sealing temperature within the range of ambient to 250 deg C.
Fast determination of temperature profiles: By choosing five different sealing temperatures, you can create a complete temperature profile of the sealability in a single test operation.
Dwell time selectable for the whole range: For all five sealing jaws, you can preset a dwell time within the range of 0.1 sec to 99.9 sec.
Variable sealing pressure: The sealing pressure will be adjusted using sets of weights. By adding disc weights to the standard sealing jaws you can cover a sealing pressure within the range of 0.14 psi to 4 psi (0.1 N/cm2 to 2.76 N/cm2).
User friendly: The sealing process is initiated with the press of a button or via a footswitch.
Good reproducibility of the sealing results: High-quality components and an auto-tuning PID temperature control ensures reliable results.
Simple Test Equipment Monitoring: To assure the reliability of the test results (according to ISO 9001) the HL-5 is calibrated with traceable UKAS test equipment for temperature, pressure and dwell time. With each supply a calibration certificate is enclosed with the machine ensuring the instrument is working to within acceptable tolerances.
Customisation: Let us customize your machine to meet your specific test lab requirements.
