Why Induction Sealing is an Effective Method of Tamper-Evidence

Induction sealing is a non-contact heating process that accomplishes the hermetic sealing of a container with a closure that includes a heat-sealable foil laminate inside of the closure. When the appropriate type of seal is used, the seal cannot be removed without leaving evidence on the lip of the container.

Pharmaceutical companies began using induction sealing in the 1980s to protect their OTC products. In fact, the FDA recognizes induction sealing as an effective means of providing tamper-evidence. Consumers now expect a “safety-seal” when they open a container filled with pills, tablets or liquid OTC products.

Packagers have found an induction seal provides additional benefits beyond safety. The hermetic seal acts as a barrier, keeping products such as oysters fresh. Leaks are also eliminated with the use of an induction seal and can be found on many liquid products such as milk and oils.

Many food companies are already using induction seals for the reasons mentioned above. Many more have been recently contacting us to specify a system solution for their application. For more information on how a cap sealer operates, contact us at 262-255-6070.
