An induction sealing machine is a heat-sealing device in packaging operations to seal containers, particularly bottles or jars, with induction seals or liners. Induction sealing is a method that creates a hermetic seal by applying heat generated by electromagnetic induction to a foil seal placed on the container opening.
The cap foil sealer machine consists of several components, including an induction heat-seal head, a power supply, and a conveyor system. The process starts by placing the container with the closure and foil seal onto the conveyor belt. As the container moves through the machine, it passes under the induction sealing head.
The induction sealing head emits a high-frequency electromagnetic field, which activates the foil seal by heating it. The heat causes the foil seal to bond with the container’s rim, creating an airtight and tamper-evident seal. The heat generated is focused only on the foil seal, so the rest of the container and its contents remain unaffected.
The foil heat-sealing provides numerous benefits, such as preventing product leakage, extending shelf life, preserving freshness, and ensuring product integrity. This technology is available using to many industries such as pharmaceuticals, food and beverages, cosmetics, and chemicals.
Different types of induction cap sealer machines are available, including handheld induction sealer for small-scale operations, and fully automated induction sealer systems for high-volume inline production lines. The induction sealer machines are adjustable to accommodate various container sizes and closure types, making them versatile for different packaging requirements.
