Induction Sealing Machines

At The Cary Company, our induction sealing machines are designed to provide secure, tamper-evident closures for a wide range of containers. These machines use electromagnetic induction to bond foil liners to the rim of bottles and jars, helping prevent leaks, preserve freshness, and extend shelf life. We carry options from compact handheld induction sealers like the Super Seal™ Jr. to high-performance induction cap sealer machines such as the Super Seal™ 400, giving customers flexibility whether they need portable sealing or continuous production line solutions.

Our induction sealer for bottles works specifically with foil-lined caps that are designed for induction sealing. These induction liners typically include a layer of aluminum foil paired with a heat-activated polymer coating. When placed under an induction cap sealing machine, the foil heats up and bonds to the container’s rim, creating an airtight and tamper-evident seal. It’s important to note that not all cap liners are compatible, so our team recommends testing sample caps and bottles to ensure proper performance with your chosen induction sealing machines.

While both methods create secure seals, induction sealing machines differ from traditional heat sealing in how they generate heat. Heat sealing applies direct thermal contact to bond materials, whereas an induction cap sealer machine uses electromagnetic induction to heat the foil liner without touching the cap. This makes induction sealing faster, cleaner, and more reliable for sealing bottles and jars.
