Single Piece Sealing Wads are fitted into cap of the containers and screwed around the container mouth. These capped-containers are made to pass the induction heat sealer. With the threaded cap upon bottle providing required pressure, as sealing layer cools, it adheres to bottle and provides for a perfect sealed surface.

Two piece sealing wads normally consists of a uppermost layer of paperboard (that maybe glued to the cap). The next layer is wax that is used to bond a layer of aluminum foil to the paperboard. The lowermost layer is a polymer film laminated to the foil. After the cap or closure is screwed to the container , the container is passed under an induction coil, which emits an oscillating electromagnetic field. The induction coil begins to heat-up the conductive aluminum foil. The heat melts the wax, which gets absorbed into the paperboard layer and the foil is released from the cap. The polymer film also heats and flows onto the lip of the container. After cooling, the polymer creates a bond with the container resulting in an airtight sealed product. Two piece sealing wads are used for leaving some type of secondary seal in cap so as to prevent leakage when induction seal is removed from the mouth of the container.
