Hot Tack & Heat Seal Testers from Enepay

Hot tack testing and heat seal testing with an Enepay test instrument is the most accurate and productive way to generate your packaging film seal curves. Fully automated with Enepay's Pilot software, our test systems follow ASTM F1921, ASTM F2029 and ASTM F88 for hot tack and heat seal testing.

Our MAGMA 3-station tester and NITRO 1-station tester create and test heat seals under a wide range of programmable pressures, temperatures, dwell times and test speeds. The systems produce curves and statistics such as heat seal strength versus temperature, hot tack strength versus temperature, and averages and standard deviations of force data.


Precision hot tack and heat seal data

Introducing the NITRO 1-Station Tester!

For years the MAGMA 3-station hot tack and heat seal test system has set the standard for testing productivity and precision. Now, Enepay is introducing its new NITRO 1-station test system. The NITRO will start shipping in the fall of 2020.

The NITRO is a budget-friendly hot tack and heat seal test system for labs with lower volume testing demands. It has the same mechanical and electronic platform as the MAGMA and uses the same Pilot software.

Hand-friendly specimen loading

Insert film specimens into the auto-clamping, side-entry grips with an easy, single motion. After testing simply remove with a single pull. No struggling with thumbscrews or levers.

High accuracy seal data

Detect subtle variations in film properties. Precise data is assured with high sensitivity load cells, independent temperature control for all sealing jaws, and fully automated test control.

High value for packaging lab

Greatly increase your testing throughput while improving the quality of your heat seal and hot tack data. MAGMA and NITRO are the highest value heat seal test systems available.

Safety is our priority

All tests are safely done behind the protective clear guard door. This provides protection against operator harm, as none of the high-speed machine parts are exposed during test execution.
