How does Induction Sealing Work?
Once the container has been filled and a cap fitted with a foil liner is applied,
the container then moves under an induction sealer. A regulated electromagnetic field transfers energy to the foil liner in the lid as it goes under the sealer, producing heat. This heat melts the sealing material on the foil liner. The liner clings to the container’s neck once this sealant cools, making a stable but versatile hermetic seal. This airtight seal ensures the substance can’t leak out, and bacteria will not get in. It also offers interference and counterfeiting security.
Benefits of Induction sealing
Prevents leaks: In induction sealing, the technology used ensures airtight sealing that can withstand tremendous pressure. This means that during storage, the transportation phase, or until your customer is ready to use your product, your product would not leak.
Tamper evidence and counterfeit protection: Induction sealing will provide its users with tamper-proof as foils must be removed or damaged for the product to be accessed. For the protection and comfort of the end-users, this is especially necessary. The end-user realizes the item has not been interfered with and can be confident of its validity thanks to a secure seal.
Increased Productivity: When contrasted to other sealing methods, induction sealing technology is also lauded by users for increasing efficiency. Induction sealing machines can run at high speed and eliminate the need for the product to be touched or treated. They can be immediately and ready to use. Therefore, no time by long periods of warming up and cooling down, as encountered with conduction sealing, is essential to maintain proper sealing temperatures. It is also simpler to transfer induction sealers from one production line to another since they can easily position over a current conveyor section. No time is lost, and without further delay, production will go on.
Virtually no maintenance: To continue to operate effectively and reliably, the new range of air-cooled sealers needs virtually no maintenance or consumables. Some of our clients describe their 20-year-old computers as like new’. Unlike other sealing methods, since no interaction occurs between the sealer and the containers, an induction sealer does not need to be cleaned daily.
Eco-friendly: Induction sealing provides a solution that, compared to other sealing systems such as conduction, is more environmentally friendly as it consumes less energy. Many producers can lower the thickness of the foil and the quantity of plastic used in the seal and container by switching to induction sealing. With a tab for fast opening, the foils can be peelable, and the peel strength is variable and can be up to your desired strength.
Extend shelf life and maintain product freshness: Induction liners serve as hermetic seals that prevent the transfer of oxygen and moisture into the item. It helps protect the product and increase its shelf life by up to three months in some instances.
