Induction sealing system

Induction sealing is the safest and cleanest system to close a container made of any material and for any industry. It can avoid leaks and offers a guarantee of immunity to consumer.

Containers Induction sealing system is a clean and no-contact system which a aluminium liner is stuck to the top of the container.

Induction sealing system was developed 35 years ago to prevent leaks in plastic containers of quimical products. Nowadays, it is the only process that can be used with almost any type of container and closure for the sealing of food, beverages, medicines, solvents, agrochemicals....

In order to seal a container by induction sealing system is needed, first of all, a plastic cap- NOT metal cap. Induction liner has already to be well set in the cap. Once the container is closed with the cap, you can use the induction sealing machine. Electromagentic camp from the machine cap penetrets the cap and heats induction liner aluminium sheet and, furthermore. it melts away the polímer sheet from de liner. After a few seconds, you can see the contanier is absolutely sealed.

All and all, this kind of closing avoids leaks of the product in transport and offers security because allow to keep the product closed and makes the product life longer. In general, will strenght the trust on the product.

Operation of the induction machine head or coil:

This part of the machine is the one that transmits the magnetic field and can be of two types: flat coil or tunnel coil. The tunnel coil has the advantage of placing the bottle in the centre and often has a deeper and more uniform field around the lid. This makes it particularly suitable in closures where the induction seal liner is located deep inside, such as sports and child-resistant beverage lids. Flat coils are more universal and suitable for use in filling machines using different cap sizes.

Requirements for a good induction seal:

The secret to a good induction sealing lies in the correct amount of heat reaching the aluminium and it being evenly distributed over the entire surface. So it is important to correctly set the power of the heat sealant, the distance between the lid and the sealing head, and the speed of the conveyor belt.

Applications of this type of sealing:

It is a widely used system in the industrial sector for its reliability and good finish, that helps to keep the product at its highest quality for longer.

Some of the fields in which it is used are:

Industry Packaged and induction sealed products.
