Induction Sealing is a very effective and versatile solution to maintaining a sterile or sealed environment in which products can be contained far beyond their normal shelf life. It is a non-contact heating process that consists of a small metallic or foil disc being placed in between the inside of the cap and top of the bottle/container.

Induction sealing has many applications in popular industries such as food, pharmaceutical, cosmetic, health care, veterinary, automotive and industrial - products ranging from cooking oil, tablets, milk, sauce, drinks, cheese, detergents, dried goods (eg.nuts, chocolate), spreads, condiments and deserts.

The process is carried out in two parts, supply of power to the machine and the transfer of that power to the sealing head where it creates an electromagnetic field which heats the foil to melt the polymer coating that welds it to the top of the container. In the two piece induction seal it would also melt the wax layer above which is absorbed into the pulp or cardboard layer releasing the foil so you can remove the cap without upsetting the foil.

There are different types of induction seal, namely two piece and one piece, two piece is where a secondary seal is left inside the cap after the induction seal has been applied, enabling a soft surface with which to seal the container after opening, the one piece seal does not leave anything behind and so relies on the marriage of the cap and bottle to create their own seal if required after opening.
