Induction Cap Sealing delivers many benefits compared to Conduction Sealing

Conduction sealing has been the most utilised method of sealing a liner to a non-screw cap or capless container. The conduction “hot-plate“ applies pressure pushing the foil or plastic film liner onto the container and melts the layer on the under surface to create a closure.

The “hot-plate” takes time to heat up (and cool down when maintenance is required). The process incurs relatively high energy costs, raises the ambient temperature and can be potentially hazardous to operators.

Unlike induction cap sealers the conduction “hot-plate” is intolerant of container height and rim variations, so out of “spec” containers may not seal or have poor seals, creating scrap and wastage. Should a spillage occur clean-up is difficult as spillages often “bake on” requiring shutdown, cooling down time and cleaning, causing a substantial reduction in production output.

Conduction sealing has been a reliable sealing method for manufacturers over the decades, however Induction Cap Sealing is faster and more energy efficient, thus reducing unit cost of the sealed product.

How does induction cap sealing work?

Induction cap sealing is a very simple and straightforward process. The container is filled and the cap (fitted with a foil liner) is applied.
