    1. Check the sealer heating bars (jaws) to be sure they are clean and free of any residue.

    2. Rotate the knob on the temperature dial to the recommended sealing temperature specified by the manufacturer of the barrier material you will be using. Remove any flammable objects surrounding the sealer.

    3. Plug the electrical cord into a 110Volt outlet. LED (light) will begin to blink. Note: Heating bars will immediately begin to heat up.

    4. Wait 5 to 6 minutes for the sealer to reach the set temperature. LED will stay on when set temperature is reached.

    5. Now you are ready to begin sealing. Position the two (2) pieces of barrier material (sealable sides together) squarely together and clamp the jaws shut. Count the appropriate number of seconds (dwell time) as recommended by the material manufacturer. Release the jaws and inspect the seal. The seal will require a few seconds to cool.

    6. When sealing in a continuous line, overlap each sealing application by approximately ½”.

    7. Inspect all your seals after completion.

    8. Unplug the sealer when finished and allow it to cool for one (1) hour before storing.

    Note: Do not carry the sealer by the cord. Use the handle.

    Weekly Maintenance: Check the Stud Assembly for loose nuts and tighten if needed.

What Are Hermetic Heat Seals and Do You Need Them?

Heat seals and flexible packaging go hand-in-hand. They are inseparable, which is exactly what you want your heat seal to be. The integrity of your packaging product is critical. Although some applications don’t require an airtight hermetic seal, most that we work on do. We find ourselves redoing products done elsewhere that didn’t live up to the standards customers expect. We go in-depth on the what, why, and how of hermetic heat seals in this video.
