One aspect of packaging that frequently gets overlooked is sealing. You can have the perfect design and label for your product but if your package isn’t sealed properly, it will all be nothing.

Induction Sealing Wad plays a significant role when it comes to a product’s packaging. It creates a hermetic seal through a closure that is lined with a heat-seal foil cover. The hermetic seal make sure the package is airtight and preserves the materials by keeping any contaminants from entering.

This type of sealing is used across numerous industries including –

  • Pharmaceutical
  • Nutraceutical
  • Automotive
  • Food and Beverage
  • Health and Beauty

An Induction sealing wad can be used in any industry that has a jar or bottle involved.

In recent times, there has been a heavy emphasis on using induction seals for products that are being sold and shipped through ecommerce. FedEx, UPS & Amazon are encouraging online retailers to use induction seals on their products to help protect them during shipping. Ensuring safer shipping is just one example of the advantages induction seals provide.

The Benefits of Using Induction Sealing Wad

The use of induction seals offers many benefits to companies that use this kind of sealing on their products’ packaging. Mainly, induction seals provide tamper evidence. Because there is a heat seal that offers a layer of safeguard, the seal providers a safe seal that allows tampering to easily be identified.

Secondly, they preserve the contents inside the packaging by preventing oxygen as well as moisture from entering the package. This extends a product’s shelf life & quality from production to consumption or use.

As mentioned earlier, another benefit of using induction seals is the prevention of leaks with packages that contain a liquid content. The seal provides additional strength and security to the package’s opening to prevent leaking whether it is being shipped or transported from the store to a consumer’s home.

How Induction Sealing Wad Work?

The anatomy of an induction seal is actually quite simple. The process of using an electromagnetic field when applying the seal to the package is where science plays an important role. Induction seals, in their most essential form, are made of three main layers:

  • FOIL

The layer closest to the opening is the heat seal that is fond of the package. Next, there is a layer of foil placed over the seal, which is followed by a backing that gives structure to the liner.

Since Induction Sealing Wad is a non-contact process, it is vital to understand how the process works without an individual essentially touching the package.

For this process to be successful, there are three key principles that require to take place:

  • Pressure
  • Heat
  • Time

To make sure the integrity of the induction sealing process, there has to be sufficient cap application torque. This torque allows caps to be put on with adequate pressure to complete the seal of the liner to the container. Without the right amount of pressure, the cap will not seal properly and this will result in leaks and other issues.

Using an induction sealing machine generates heat through an electromagnetic field, which interacts with as well as heats up the foil layer within the liner. This in turn melts the associated heat seal layer to bind the liner to the container. The heating stage in the induction seal process is what permits this to be done with no contact.
