Abstract

This thesis investigates the temperature recorded during the induction sealing process within the headspace of a container. The topic for this thesis stemmed from a question of whether or not the product inside an induction sealed bottle has the potential of being adversely affected by heat generated during the induction sealing process on a packaging line during production. The thesis demonstrated the heat generated and temperature recorded utilizing irreversible chemical temperature indicating labels during the induction sealing process on a standard bottle packaging line with an aluminum foil liner/innerseal. Based on the results of this study, the following trends were observed: as the induction seal head height increased above the container/closure system, the temperature at the foil innerseal decreased and the distance from the top of the bottle finish down into the bottle headspace that a temperature could be measured decreased. As the packaging line speed increased, the temperature at the foil innerseal decreased and the distance measured from the top of the bottle finish down into the bottle headspace that a temperature could be measured decreased. As the diameter of the foil innerseal increased with the increase in closure diameter, the temperature at the foil innerseal increased and the distance measured from the top of the bottle finish down into the headspace that a temperature could be measured increased. In no case did the temperature at the product fill level of any of the tested container/closure systems exceed 100F. Therefore it can be concluded that the induction sealing process does not introduce temperatures high enough that would adversely affect the contents of a container/closure system.
