Induction sealer is one of those convenient and extra ordinary working gadgets that can assist you in sealing different bottles in a non-contact way via fabrication and heat.

This blog post is going to explain many useful things about Induction sealer, explaining how it is used, how it works and much more. So keep reading.


Aipak Induction Sealer

An induction sealer is a machine that uses inductive heating to seal containers. This type of machine is commonly used in the pharmaceutical, and food industries, as it provides a hermetic seal that can keep contents fresh for a longer period of time.

An induction sealer works by creating an electromagnetic field that generates heat when it comes into contact with a conductive material. When this happens, the heat creates a seal that bonds the lid to the container.

An Induction sealer is often used to seal containers that contain liquid or semi-solid contents. This type of seal is necessary in order to prevent leakage and maintain product freshness.

The Induction sealer is available in a variety of sizes and power levels. The size of the machine will depend on the size of the containers that need to be sealed. The power level will determine the speed at which the machine can seal containers.


Induction Sealer working

An induction sealer is a machine that uses induction heating to seal containers (usually bottles or cans) with aluminum foil or other materials.

Induction sealing is a non-contact heating process that uses electromagnetic induction to heat an inductor (coil) in close proximity to the container lid.

The inductor creates an oscillating magnetic field that induces an electric current in the conductive material of the container lid.

The electric current creates resistance heating that melts the aluminum foil, which then bonds to the container lip, creating a hermetic seal.

Induction sealers are used in a wide variety of industries, including food and beverage, pharmaceuticals, cosmetics, and chemicals.

They are also used for sealing containers that need to be sterile or have a tight seal, such as those used for medical purposes.


1KW Induction Sealer

Induction sealers are present in different sizes and shapes in the market. That is why there some components are different from each other.

But also, some components are common in very induction sealers. These common components are the main components of the machine. These are as follows:

Power Supply

The power supply provides the electricity that is needed to generate the magnetic field. At the very first it provides the electricity to the inverter from the wall socket.

After that, the inverter helps the machine seal all the bottles by transforming electricity into the machine and make usable for sealing purposes.

The demand for electricity is varied from one induction sealer to other. So, it is up to your which sealer you want you. You just have to keep in mind to confirm the power rating of induction the sealer.

Moreover, the manual induction sealer needs a power supply of approximately 1 kilowatt. So, it starts working on this power supply.

But on the other hand, the automatic induction sealer almost needs a 6-kilowatts power supply, which is much more than the manual one.

So, this is how the main power supply of induction sealer works.

Sealing Head


The second main component of the induction sealer is the sealing head. The size of the sealing head mainly depends on the number of bottles that are required for sealing. It can be small or big.

The Sealing head has a sealing coil. The coil creates the magnetic field that heats the foil. Also, the coil is a great conductor of metal. But the coverage of coil is mostly done with plastic.

There are also two types of coils present in the market. You can use any kind of coin for your induction sealer. These two designs of sealing coils are as follows:

  • Tunnel Coils
  • Flat Coils

Tunnel sealing coils are basically used for caps like flip-top, dispensing, or spouted ones. This type of coil is not considered as much suitable for sealing solid material.

The flat sealing coils are considered suitable for sealing the flat caps because they have inner sealers.

So, it is up to you what type of material you require for sealing, and choose the sealing coil according to that material.


The third main component of the induction sealer is the controller. The main working of the controller is that it regulates the power supply and controls the heating process.

The Controller is considered a very critical component of the induction seal. Because all the heating process depends on it.

Induction sealers have different types that are present in the market. These types are as follows:

Portable Sealers


Portable Induction Sealer

The very first type of induction sealing is portable sealers. The portable sealers have all the equipment that can be easily manipulated.

Also, this type of induction sealer is very flexible compared to the others. So, portable sealers are smaller and less expensive, but they’re still powerful enough for most sealing applications.

Portable induction sealers are easy to use. It has multi-functions in it. They can be easily moveable from one workplace to another.

These are also available in many designs in the market. Also, it is adjustable and very lightweight.



A basic portable induction sealer contains a liner which holds the adhesive foil layer in it. A heating induction heats the foil and a cap threading happen in which foil is sealed on top of the bottle mouth then the induction sealer puts the cap on it.


  • Easy to carry in light weight.
  • Less expensive and price efficient.
  • Reliable for small business use.


  • You will face difficulties working with large production sealing.
  • Sometimes it will cause unusual sealing because of high heating.

Working Components

Here are some working parts of the portable induction sealer.

Sealing Handle

Control Panel

You will see different buttons and a small display screen on the screen panel which gives you the power to perform multiple operations as well as give you visual display.

Tabletop Sealer


The second type of induction sealer is a tabletop sealer. Tabletop sealers are larger and more expensive than portable sealers, but they offer more power and features.

They are not easy to move as their size is larger. They are also easy to use.


Tabletop induction sealer works in a different way as compared to some other induction sealer. When the product comes on the conveyor the metallic rode on both sides hold the product in a desired position.

After which the sealing induction assembly from top comes down on to the bottle and then seal the bottles with a induction film and puts the cap and seal it by applying torque.


  • Beneficial to induction seal large size bottles.
  • Comes in a fully automation to achieve large production.
  • Fast, reliable and effective for business use with handy actions.


  • A little noisy and expensive so, not environment friendly that much.
  • Not reliable to work with metal caps induction sealing.


Here are some tabletop induction sealer machine common working components.

Conveyor Belt

Conveyor Belt

This moving component in the induction sealing machine covers the baseline of the tabletop induction sealer to help control the forward movement of the bottles.

Metal Bars

One of the basic components and very important one in tabletop induction these metal bars are present on both sides of the machine that helps in controlling the products on the conveyor.

As well as, these metal bars also controls the induction assembly by holding it on top of the conveyor.

Power Motor

A powerful part works to provide power as the name suggests. Because it will be hard to control the induction assembly manually so a power unit must need to exists.

Manual Induction Sealer


The next type is the manual induction sealer. It is a fully manually driven machine. This machine is mainly used in small-scale industries.

Although the price of this manual induction sealer is comparatively low as compared to the others.

But also, this machine is not suitable for extensive manufacturing. And seals very less bottles as compared to the others. You cannot seal a metallic bottle from it.

It is also in very small size and has very less weight. Easy to use but required a worker that manually seals the bottles from it.


Manual induction sealer

A manual induction sealer works just like a portable induction sealer which comes with a portable handle. The only difference is that you have to perform the induction process manually by using an induction handler.

You need to adjust some settings manually like heating temperature before induction sealing any product in this machine.


  • Very flexible and user friendly for induction sealing multiple size vials.
  • Hermatic seal in a perfect way with less errors chances.
