The principle of electromagnetic induction heating is that the high-frequency current go through the inductor coil and create a magnetic field. When the magnetic field lines pass through the foil material, they instantly generate a large number of small eddy currents. This high-speed self-heating makes the aluminum foil composite sol melt, achieving a perfect seal. This non-contact sealing machine instantly produces heat, fusing the aluminum foil directly onto the bottle mouth.

Application: This handheld induction sealing machine is widely used in pharmaceutical, chemical, food, beverage, cosmetic, and lubricant industries for sealing plastic, glass, and other non-metal containers.
