Induction sealing machines utilize induction of heat to achieve sealing of containers. The induction of heat is achieved electrically by a conducting object. For instance, a machine encompasses an electro-magnetic induction and with the help of eddy currents, heat is generated.
Induction Sealing Machine Working Principle
An inner seal is used over the container which is generally made up of PVC, ABS, polythene, and thermoplastic material. An excellent induction sealing needs a fine neck finishing.
An induction sealing machine works by the principle of conduction. For example, the heating of aluminium foil takes place via a high-frequency magnetic field produced by an induction unit. The whole route is a non-contact process that does not involve direct heat.
Working of induction sealing machine- Picture courtesy - Enercon
A multi-layer sealable closure is consisting of a sealable film, wax, and aluminum foil. Soon after the capping of a container, it passes over the induction unit. The induction unit develops heat which results in the warming up of aluminium layers as well as other materials.
So, wax begins to melt and attempt to penetrate the board layer. The entire sealing layer melts and develops firm sealing against the opening of a container.
Thus, when you open the container, you will find permanently sealed aluminium foil surrounds the rim of the container.
5.What is an aluminium induction sealing liner?
You have possibly seen a firm covering over bottles and jars before use, such as margarine, medicines, peanuts, etc. That covering is made up of aluminium foil sealed by an induction sealing machine. This aluminium foil over the container also ensures that the following product is tampered evident.
A typical aluminium sealing liner is made up of the following strategically designed layers:

A) A seamer head
B) A power supply
Without these major components’ induction sealing machines can’t work. The sealing head gets a plastic enclosed coil conductor, which emits an electromagnetic current.
So, when you supply electric current, an inductive coil gets heat up. The cap of the fitted container passes this electric current; thus the inner sealing of aluminium foil heats up and associated material melts down resulting in a firm bond with the container’s opening.
A) Seamer Head
A seamer head is comprised of a coiled conductor along with a plastic house. When a capped container passes by this, aluminium foil gets stamp onto the container to seal it firmly. The design and development of the seamer head is depending upon your applications. The most demanding designs of seamer heads are flat and tunnel.
- Flat Seamer Head: a wide electromagnetic field falling from the head.
- Tunnel Seamer Head: it is designed in a way that emits a strong magnetic field just from above and along with the sides of the cap.
Thus, it can seal a broader area and adjustable for a series of closures devoid of modifying the seamer head.
B) Power Supply
The power supply is a major component where your machine gets the energy to begin the process of sealing.
The suitable strength of this machine’s power supply is entirely based on the size of container closure and the pace of the production line.

This machine can help you to detect any compromised product packaging due to missing foil, stuck containers, tilted, and loose caps. Hence, a sealing integrity detector significantly ensures the quality and shelf-life of a product.
- Pneumatic Reject Device
This device works in parallel with the sealing integrity detector. By detecting any compromised pack, this machine can automatically detect with concomitant ejection of unsealed product on a tray. Therefore, faulty bottles and containers do not reach to end of the sealing process.
- Visible/ Audible Alarming System
A visible or audible alarming system is integrated with an induction sealing machine that can help you to know about any trouble or emergency. This alarming system is quite obvious, whether you are at distance from the sealing machine, a noticeable alarm may let you know.
13.What are the basic induction sealing packaging test methods?
1) Dry method: In the dry method, a bell-jar vacuum chamber is used which is allowed to examine by what pressure integrity of seal fails.
Some companies use an altimeter to assess pressure testing. Larger production units i.e., food packager testing is carried out in a vacuum chamber attached to an altimeter.
To pass the test, each product must maintain its sealing integrity up to 36000 feet. This test is an efficiently used method, suitable for some specific class of packaging products. It is dependent on the packager’s choice to select their standard of applying pressure for each product.
2) Bubble Leak Method
This is a most precise test, that allows you to examine leaking at a very small scale. This test is conducted on a water bath vacuum chamber. This is an ideal test for those products that have the headspace or containing an amount of space inside the container.
For testing, you can submerge the product under the water level present in the testing chamber, close the lid and apply to vacuum. If you observe a gentle stream of air bubbles escaping from the sealed pack then the sealing is compromised. The extent of packaging is varying from batch to batch.
Bubble Leaking Tester- Picture courtesy- RDM
This is another simple way to monitor the leakage or compromised seal container. For this, you need to remove a cap from the container and turn it upside down while squeezing the side of the container.
This is a good test to assess the sealing strength. However, you cannot determine a microscopic leakage by performing this test.

15.What is the difference between induction sealing and shrink-wrapping?
Although shrink wrapping is a straightforward procedure that involves covering an object or product with a shrink wrap followed by heat application. But induction sealing machines are still considered the best option for sealing the product. Some of the major difference between shrink wrap and induction sealing are:
- Heating Source:
The usage of heat causes the wrapper to shrink and allows binding according to the shape of a product. The application of heat is taking place with help of a heating gun. In contrast, an induction sealing machine induces heat with help of an induction coil which heats the aluminium foil.
- Sealing Material
Shrinkwrap film is made up of thermoplastic material. To achieve shrink wrapping you will require two materials, a shrink wrap, and a heat source. While, sealing material used for induction sealing is made up an aluminium foil with associated layers of pulp paperboard, wax, and a polymer.
Shrinkwrap must encase the entire container without overlapping. While induction sealing involved multi-layer sealing material for packaging.
- Type of heat
Shrinkwrapping requires a high- amount of heat energy to attain complete wrapping. On other hand, the induction sealing process requires a lesser amount of heat to seal.
- Safe and Secure Packaging
The shrinkwrapping process only seals the covering of the cap and neck of the bottle/container. While induction sealing process is a very secure and safe mode of sealing.
- Space Occupation
The size of the shrink wrap machine is up to 25 feet long which requires more space. Whereas induction sealing machines need only three to five feet of space.
