What is Induction alu foil liner?
Induction alu foil liner composed of backing, aluminum foil, adhesive and sealing film. After induction heating, aluminum foil layer is sealed with the bottle mouth to achieve the effect of sealing, moisture-proof and leak-proof. Inside the electromagnetic induction sealing machine, the rectifier circuit converts the 50Hz AC voltage into a DC voltage, and then the control circuit converts the DC voltage into a high-frequency voltage with a frequency of 20-100KHz. The high-speed changing current flowing through the coil will produce high-speed changes. When the magnetic field lines in the magnetic field pass through the aluminum foil, countless small eddy currents will be generated on the surface of the aluminum foil. The eddy currents make the aluminum molecules on the aluminum foil move at high speed and irregularly. Add heat seal layer on the surface of aluminum foil.

How to get right induction liners?
Firstly, please confirm the material of your bottle, because the sealing layer of the induction gasket is customized according to the material of the bottle. If it is a plastic container, what kind of plastic is it? PET/PP/PE or other material?
Secondly, check the exact liner diameter needed? Ideal diameter is the inner diameter of cap without screw, or bottle mouth diameter with screw.
Thirdly,what’s in the bottles? Food, chemicals,seasonings and so on? This is very important to check which type of liner is ideal.
