FAQ's

Yes. Some induction sealing companies have adopted a “no kilowatts necessary” policy when quoting induction sealers. 

However, kilowatt (kW) ratings are the only real measurable means of determining the exact system necessary to run your product. Visit www.pillartech.com to learn more.

1. Tamper Evidence - Deter Pilferage
2. Leak Prevention
3. Increased Shelf Life - Product Freshness

Where any of the above conditions are preferred and/or mandated, Pillar Technologies can supply the right induction sealer to fulfill your requirement. Qualified Pillar personnel are always available to answer questions about induction sealing. Pillar has a fully functional lab to run your samples for inspection. Just give us a call.

Power supplies are independent from the sealing coils providing unsurpassed flexibiliity. And, our coils can be repaired - a tremendous cost savings.

Yes. Overheating the foil causes damage to the seal layer and to any protective barriers. This could result in faulty seals, even weeks after the initial sealing process.

Yes, but all parameters must be closely monitored. Call the experts at Pillar if you’re considering metal caps.

Yes, dry products are no problem. Liquid products in glass containers are generally not conducive to induction sealing. Stability tests are recommended whenever using glass containers.

Yes, capless sealing is available. Since each capless operation is unique, Pillar addresses capless sealing on a case-by-case basis. We look forward to serving you.

Induction sealing is a method of hermetically sealing rigid containers to provide tamper evidence, preserve freshness, deter pilferage and prevent leakage while providing product integrity.

In most applications, packagers purchase induction foil lined caps from a cap supplier. Cap styles of all varieties are available from these suppliers. 

After filling and capping, the container passes under an induction coil which emits a varying electromagnetic field and the conductive aluminum foil liner begins to heat. The polymer film on the liner also heats and flows onto the lip of the container. When cooled, the polymer creates a bond with the container resulting in a sealed product.

Simple. Waterless systems are less than one-half the size of previous generation water-cooled systems as we’ve eliminated the filters, hoses, pumps, radiators, flow switches, water and mess. And, the new waterless designs are practically maintenance free, saving you time and money

Sealing speed is largely dependent on the diameter of the foil, the style of cap, the speed of your conveyor, the power supply size, and the induction coil. Pillar will match up the proper equipment for your application.
