1. What are the advantages of induction sealing over conventional sealing?

Induction sealing is a much better sealing technology than conventional conduction sealing . The major advantages are:

• It simply creates a very strong sealing liner.
• Extremely high speed of operation as compared to conduction.
• Extremely high speed sealing.
• Cooler operation
• Reduced power consumption.

2. What is induction sealing?

Induction sealing is a process of sealing metallised foil seal on the top of plastic or glass container through a non contact (induction/electromagnetic) method of heating.

3. What is an Induction Seal (or Induction Wad) made of?

The induction seal (or induction wad) basically consists of four layers

• Cardboard or Foam Packing
• Wax Layer
• Aluminum Foil
• Sealing Film

4. How does induction sealing work?

A typical induction seal usually consists of a paper /pupl board followed by a wax layer and finally an aluminum foil laminated with sealable polymer film.

When passed through an induction sealer, the electromagnetic field heats the aluminum film resulting in sealing of polymer film on the bottle neck. The heat also causes melting of wax, which in turn releases the foil seal and the backing material (paper /pulp) is retained in the cap.

5. Is induction sealing possible on all kinds of bottles/containers?

Yes almost all, it is possible on glass, PVC, PE, PET, polystyrene and polypropylene containers.
