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

Innerseals meet the stringent requirements of the Food and Drug Administration (FDA) and can be used on containers of all compositions

Containers are filled and capped by the existing process using the caps that are now prelined with the Induction Innerseal rather than the standard liner. The cap is then exposed to an electromagnetic field generated by a sealing head. The field, unaffected by the package or product, penetrates the cap and induces a strong electrical current in the foil. The current generates heat that melts the liner heat seal film. As the container leaves the field and the structures cool, the foil is heat sealed to the container finish.

Tamper Evident: Foil innerseal discourages tampering by showing evidence of post-packaging entry into container.
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 a pilferer and makes 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.
