The induction sealing process bonds a foil laminate inner seal to the lip of a container. After the container has been filled and capped with an induction-lined closure, it passes underneath the induction sealing system. The non-contact heating process welds the liner to the container creating a hermetic seal. The FDA regards induction sealing to be an effective method of tamper evidence
When properly applied, induction lined caps provide a hermetic, leak proof, and tamper evident seal. Using an induction sealing system is ideal for extending product shelf life, preserving freshness, preventing costly leaks and enhancing your product's value.
