What is induction cap sealing?
The magnetic induction sealing is a non-contact cap sealing operation. When the bottles reach the electro-magnetic field, they are magnetized through an electro magnetic induction heating effect. The aluminum foil is quickly heated to the desired temperature. The content of the bottles is not induced by the electro magnetic field, but the heat seal film with aluminum foil attached on the cap (such as FDA approved inner seal) is. When the aluminum foil is heated by the coil of induction cap sealing machine, the heat is then transferred to the heat seal film, which quickly reaches the melting point, and becomes an adhesive to bond the cap foil and bottle.
