Induction Heating - Cap Sealing

Induction sealing is a non-contact process by which a foil "seal" is bonded to a container. This unique process can be used with almost any style container and closure for sealing foods, medicine, beverages, solvents and chemicals.

Containers are filled and capped by the current process, however the caps are now prelined with the Induction Innerseal rather than the standard liner. The cap is then presented to an electromagnetic field generated by either a low volume manually held, or a high volume conveyor mounted sealing head. The field, unaffected by the package or product, penetrates the cap and induces a strong electrical current in the foil structure of the seal. The current generates heat that will melt the liner heat seal film. As the container leaves the field and the structures cool, the heat seal film bonds to the container finish.

Product Protection

Tamper Evident: Innerseals guard against tampering and show at a glance if the product has been violated.

Leak Proof: Eliminates costly and messy recalls due to product leakage.

Increases Shelf Life: Innerseals form an airtight barrier to "lock" in product freshness, reducing spoilage, evaporation and increasing shelf life.

Reduces Pilferage: Bonded foil seals discourage theft and make the product a less likely target.

Enhances Customer Confidence: The user sees the seal's integrity and feels secure that the product is unadulterated and fresh
