How to Install Heat Induction Seal (HIS) Lined Caps Onto Your Bottle

Our Handheld, Induction Sealing Machines are designed to hermetically seal special liners called "Heat Induction Seal Liners" or, "HIS Liners" to both PLASTIC and GLASS containers. HIS Liners are specifically designed to seal IN liquid products (preventing leakage), and for sealing OUT moisture. Thereby protecting moisture sensitive products like powders and pills. Our Induction Sealer can comfortably handle cap sizes from 20mm to 100mm in size.

We’ve provide a set of simple instructions on how to use the Handheld, Induction Sealer that we offer.


1. Remove the sealer from it's box. Plug in the power cord, and then turn it on. Check to ensure that all of the LED readouts are functioning and are at zero. If they are not, turn off the sealer, unplug it. Wait a few seconds, then plug the cord back into the outlet and turn the sealer on again.



2. Screw a cap lined with an HIS liner onto the neck of your bottle. Make sure the cap is fully tightened down and snug.


3. Place the wand so that the wider end rests directly on top and centered over the cap. And press the red button. Keep pressing the red button until the timer finishes counting down to ZERO.


4. Remove the wand from the cap, and allow the cap to cool for about 5 minutes.


5. Remove the cap and inspect the liner. Test it for adhesion to the sealing surface. If the seal did NOT adhere properly to the sealing surface. Get a fresh, new cap... and try it again from step 1, but with increased time. Please be careful, it is possible to have the wand on the cap to long, till it burns the liner. You will need to use discrepancy and a bit of testing to find the right timing "sweet spot" for the caps and container you are using.


6. Once you can verify that the liner has properly adhered to the sealing surface of the bottle neck, without burning the liner. You can go ahead and continue on to sealing the rest of your lined caps to their bottles. With some practice, you can expect to be able to seal about 20 liners per minute.


Resolving Problems - Are your HIS lined caps not adhering to the mating surface of your container? Even after you've tried keeping the wand on longer? These are the following FOUR most likely causes.

Cap Improperly Installed - We know this sounds silly. But it's important that the cap is screwed down straight, and is firmly threaded onto the neck of the container.

Wand Was Not Held Properly to The Cap - To achieve a reliable seal. The Sealer wand should be held directly, and perpendicular over the cap and bottle. Holding the wand at an angle, or slant. Can cause the liner to heat unevenly and limit its ability to properly seal the liner to the container.

Dirty, or Damaged Sealing Surface - Make sure the sealing surface is clean and free of spilled product. Inspect the surface for dents, scratches, nicks or warping. For the most part, the HIS liner adhesive can compensate for some imperfections on the sealing surface. But its best to start with a clean, undamaged sealing surface.

Liner is Not Rated For the Container Material If the HIS Liner you are using is not specifically rated for the glass or plastic material of the container you are using. Chances are likely that the liner will not adhere properly. Check to make sure you have the right liner for the right container material.
