This machine achieves the non-contact method to seal the containers. As the container passes through the induction coil the conductive aluminum foil liner begins to heat due to eddy currents. The heat melts the wax, which is absorbed into the pulp backing and releases the foil from the cap. The polymer film also heats and flows onto the lip of the container. When cooled, the polymer creates a bond with the container resulting in a hermetically sealed product.
With the advantages the induction sealing machine have, it’s widely used in a variety of products, such as food, beverage, medicine, chemical, cosmetics, pastes etc.
